Release 8    Overview of Canopy Networks                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  101     8.2 BH-BH LINKS Canopy BHs communicate with each other using a point-to-point protocol. This point-to-point protocol uses a 2.5-msec frame. A BH link has higher throughput and lower latency (typically 5 msec, 2.5 msec in each direction) for two reasons:  ◦  Only two endpoints are involved. ◦  No bandwidth request and reservation process is involved.  For 10-Mbps BHs, the aggregate throughput on the channel is 7.5 Mbps. For 20-Mbps BHs, the aggregate throughput on the channel is 14 Mbps. If a BH is set to a downlink ratio of 50%, then the bandwidth in each direction is half of the total BH link bandwidth.

Such a key arrives from Motorola as a filename.url file. When you double-click on this file, your browser opens and the location bar is populated by a lengthy string. This URL string begins with http://<ModuleIPAddress>/. If you need to load a key into a module whose IP address has changed since Motorola issued the key, perform the following steps. Procedure 1: Modifying a fixed license key for a module IP address 1.  Right-click on the license key filename. 2.  Select Properties. 3.  Select the Web Document tab. 4.  At URL, substitute the current IP address for the original IP address in the URL. 5.  Click OK. 6.  Double-click on the license key filename. RESULT: The key loads into the module.

Open the Configuration web page of the module. 8.  Review parameter settings and enable the feature if you wish to do so at this time (see next section). =========================== end of procedure =========================== 10.2 ENABLING FEATURES A Canopy feature is enabled (functioning) if the feature is both active and enabled. For example, Transmit Frame Spreading is active (can be enabled) in any AP or BHM that operates on Release 8. However, Transmit Frame Spreading functions only if the Enable selection for the Transmit Frame Spreading parameter is checked in the Radio tab of the Configuration web page in the module.

Issue 2, November 2007  Draft 5 for Regulatory Review  117     11 ACQUIRING PROFICIENCIES Designing and operating a Canopy network requires fundamental knowledge of radio frequency transmission and reception, Internet Protocol addressing schemes, experimentation with Canopy equipment, and for most operators participation in some forms of Canopy training. 11.1 UNDERSTANDING RF FUNDAMENTALS Canopy training and user interfaces presume an understanding of RF fundamentals. Excellent written sources for these fundamentals are available. One such source is Deploying License-Free Wireless Wide-Area Networks by Jack Unger (ISBN 1-58705-069-2), published by Cisco Press. 11.2 UNDERSTANDING IP FUNDAMENTALS Canopy training and user interfaces also presume an understanding of Internet Protocol (IP) fundamentals. Excellent written sources for these fundamentals are available. One such source is Sams Teach Yourself TCP/IP in 24 Hours by Joe Casad  (ISBN 0-672-32085-1), published by Sams Publishing.

Issue 2, November 2007  Draft 5 for Regulatory Review  129     12 ENGINEERING YOUR RF COMMUNICATIONS Before diagramming network layouts, the wise course is to ◦  anticipate the correct amount of signal loss for your fade margin calculation (as defined below). ◦  recognize all permanent and transient RF signals in the environment. ◦  identify obstructions to line of sight reception. 12.1 ANTICIPATING RF SIGNAL LOSS The C/I (Carrier-to-Interference) ratio defines the strength of the intended signal relative to the collective strength of all other signals. Canopy modules typically do not require a C/I ratio greater than ◦  3 dB or less at 10-Mbps modulation and −65 dBm for 1X operation. The C/I ratio that you achieve must be even greater as the received power approaches the nominal sensitivity (−85 dBm for 1X operation). ◦  10 dB or less at 10-Mbps modulation and −65 dBm for 2X operation. The C/I ratio that you achieve must be even greater as the received power approaches the nominal sensitivity (−79 dBm for 2X operation). ◦  10 dB or less at 20-Mbps modulation.  12.1.1 Understanding Attenuation An RF signal in space is attenuated by atmospheric and other effects as a function of the distance from the initial transmission point. The further a reception point is placed from the transmission point, the weaker is the received RF signal. 12.1.2 Calculating Free Space Path Loss The attenuation that distance imposes on a signal is the free space path loss. PathLossCalcPage.xls calculates free space path loss. 12.1.3 Calculating Rx Signal Level The Rx sensitivity of each module is provided at http://motorola.canopywireless.com/prod_specs.php. The determinants in Rx signal level are illustrated in Figure 31.

Rx signal level, in turn, is a major factor in the system operating margin (fade margin), which is calculated as follows: system operating margin (fade margin) dB =Rx signal level dB  −  Rx sensitivity dB  Thus, fade margin is the difference between strength of the received signal and the strength that the receiver requires for maintaining a reliable link. A higher fade margin is characteristic of a more reliable link.
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  131     12.2 ANALYZING THE RF ENVIRONMENT An essential element in RF network planning is the analysis of spectrum usage and the strength of the signals that occupy the spectrum you are planning to use. Regardless of how you measure and log or chart the results you find (through the Spectrum Analyzer in SM and BHS feature or by using a spectrum analyzer), you should do so ◦  at various times of day. ◦  on various days of the week. ◦  periodically into the future.  As new RF neighbors move in or consumer devices in your spectrum proliferate, this will keep you aware of the dynamic possibilities for interference with your network. 12.2.1 Mapping RF Neighbor Frequencies Canopy modules allow you to ◦  use an SM or BHS (or a BHM reset to a BHS), or an AP that is temporarily transformed into an SM, as a spectrum analyzer. ◦  view a graphical display that shows power level in RSSI and dBm at 5-MHz increments throughout the frequency band range, regardless of limited selections in the Custom Radio Frequency Scan Selection List parameter of the SM. ◦  select an AP channel that minimizes interference from other RF equipment.  The SM measures only the spectrum of its manufacture. So if, for example, you wish to analyze an area for both 2.4- and 5.7-GHz activity, take both a 2.4- and 5.7-GHz SM to the area. To enable this functionality, perform the following steps:   CAUTION! The following procedure causes the SM to drop any active RF link. If a link is dropped when the spectrum analysis begins, the link can be re-established when either a 15-minute interval has elapsed or the spectrum analyzer feature is disabled.  Procedure 2: Analyzing the spectrum 1.  Predetermine a power source and interface that will work for the SM or BHS in the area you want to analyze. 2.  Take the SM or BHS, power source, and interface device to the area. 3.  Access the Tools web page of the SM or BHS. RESULT: The Tools page opens to its Spectrum Analyzer tab. An example of this tab is shown in Figure 137. 4.  Click Enable. RESULT: The feature is enabled. 5.  Click Enable again. RESULT: The system measures RSSI and dBm for each frequency in the spectrum.
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  132     6.  Travel to another location in the area. 7.  Click Enable again. RESULT: The system provides a new measurement of RSSI and dBm for each frequency in the spectrum. NOTE: Spectrum analysis mode times out 15 minutes after the mode was invoked. 8.  Repeat Steps 6 and 7 until the area has been adequately scanned and logged. =========================== end of procedure ======================  As with any other data that pertains to your business, a decision today to put the data into a retrievable database may grow in value to you over time.   RECOMMENDATION: Wherever you find the measured noise level is greater than the sensitivity of the radio that you plan to deploy, use the noise level (rather than the link budget) for your link feasibility calculations. 12.2.2 Anticipating Reflection of Radio Waves In the signal path, any object that is larger than the wavelength of the signal can reflect the signal. Such an object can even be the surface of the earth or of a river, bay, or lake. The wavelength of the signal is approximately ◦  2 inches for 5.2- and 5.7-GHz signals. ◦  5 inches for 2.4-GHz signals. ◦  12 inches for 900-MHz signals.  A reflected signal can arrive at the antenna of the receiver later than the non-reflected signal arrives. These two or more signals cause the condition known as multipath. When multipath occurs, the reflected signal cancels part of the effect of the non-reflected signal so, overall, attenuation beyond that caused by link distance occurs. This is problematic at the margin of the link budget, where the standard operating margin (fade margin) may be compromised. 12.2.3 Noting Possible Obstructions in the Fresnel Zone The Fresnel (pronounced fre·NEL) Zone is a theoretical three-dimensional area around the line of sight of an antenna transmission. Objects that penetrate this area can cause the received strength of the transmitted signal to fade. Out-of-phase reflections and absorption of the signal result in signal cancellation. The foliage of trees and plants in the Fresnel Zone can cause signal loss. Seasonal density, moisture content of the foliage, and other factors such as wind may change the amount of loss. Plan to perform frequent and regular link tests if you must transmit though foliage. 12.2.4 Radar Signature Detection and Shutdown With Release 8.1, Canopy meets ETSI EN 301 893 v1.2.3 for Dynamic Frequency Selection (DFS). DFS is a requirement in certain countries of the EU for systems like Canopy to detect interference from other systems, notably radar systems, and to avoid co-channel operation with these systems. All 5.4 GHz modules and all 5.7 GHz
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  133     Connectorized modules running Release 8.1 have DFS. Other modules running Release 8.1 do not. With Release 8.1, Canopy SMs and BHSs as well as Canopy APs and BHMs will detect radar systems. When an AP or BHM enabled for DFS boots, it receives for 1 minute, watching for the radar signature, without transmitting. If no radar pulse is detected during this minute, the module then proceeds to normal beacon transmit mode. If it does detect radar, it waits for 30 minutes without transmitting, then watches the 1 minute, and will wait again if it detects radar. If while in operation, the AP or BHM detects the radar signature, it will cease transmitting for 30 minutes and then begin the 1 minute watch routine. Since an SM or BHS only transmits if it is receiving beacon from an AP or BHM, the SMs in the sector or BHS are also not transmitting when the AP or BHM is not transmitting. When an SM or BHS with DFS boots, it scans to see if an AP or BHM is present (if it can detect a Canopy beacon). If an AP or BHM is found, the SM or BHS receives on that frequency for 1 minute to see if the radar signature is present. For an SM, if no radar pulse is detected during this 1 minute, the SM proceeds through normal steps to register to an AP. For a BHS, if no radar pulse is detected during this 1 minute, it registers, and as part of registering and ranging watches for the radar signature for another 1 minute. If the SM or BH does detect radar, it locks out that frequency for 30 minutes and continues scanning other frequencies in its scan list. Note, after an SM or BHS has seen a radar signature on a frequency and locked out that frequency, it may connect to a different AP or BHM, if color codes, transmitting frequencies, and scanned frequencies support that connection. For all modules, the module displays its DFS state on its General Status page. You can read the DFS status of the radio in the General Status tab of the Home page as one of the following: ◦ Normal Transmit ◦ Radar Detected Stop Transmitting for n minutes, where n counts down from 30 to 1. ◦ Checking Channel Availability Remaining time n seconds, where n counts down from 60 to 1. This indicates that a 30-minute shutdown has expired and the one-minute re-scan that follows is in progress.  DFS can be enabled or disabled on a module’s Radio page: Configuration > Radio > DFS. Operators in countries with regulatory requirements for DFS must not disable the feature and must ensure it is enabled after a module is reset to factory defaults. Operators in countries without regulatory requirements for DFS will most likely not want to use the feature, as it adds no value if not required, and adds an additional 1 minute to the connection process for APs, BHMs, and SMs, and 2 minutess for BHSs. −
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  134      RECOMMENDATION: Where regulations require that radar sensing and radio shutdown is enabled, you can most effectively share the spectrum with satellite services if you perform spectrum analysis and select channels that are distributed evenly across the frequency band range.  A connectorized 5.7-GHz module provides an Antenna Gain parameter. When you indicate the gain of your antenna in this field, the algorithm calculates the appropriate sensitivity to radar signals, and this reduces the occurrence of false positives (wherever the antenna gain is less than the maximum).  12.3 USING JITTER TO CHECK RECEIVED SIGNAL QUALITY (CANOPY FSK ONLY) The General Status tab in the Home page of the Canopy SM and BHS displays current values for Jitter, which is essentially a measure of interference. Interpret the jitter value as indicated in Table 29. Table 29: Signal quality levels indicated by jitter Correlation of Highest Seen  Jitter to Signal Quality Signal Modulation High Quality Questionable Quality Poor Quality 1X operation (2-level FSK) 0 to 4 5 to 14 15 2X operation (4-level FSK) 0 to 9 10 to 14 15  In your lab, an SM whose jitter value is constant at 14 may have an incoming packet efficiency of 100%. However, a deployed SM whose jitter value is 14 is likely to have even higher jitter values as interfering signals fluctuate in strength over time. So, do not consider 14 to be acceptable. Avoiding a jitter value of 15 should be the highest priority in establishing a link. At 15, jitter causes fragments to be dropped and link efficiency to suffer. Canopy modules calculate jitter based on both interference and the modulation scheme. For this reason, values on the low end of the jitter range that are significantly higher in 2X operation can still be indications of a high quality signal. For example, where the amount of interference remains constant, an SM with a jitter value of 3 in 1X operation can display a jitter value of 7 when enabled for 2X operation. However, on the high end of the jitter range, do not consider the higher values in 2X operation to be acceptable. This is because 2X operation is much more susceptible to problems from interference than is 1X. For example, where the amount of interference remains constant, an SM with a jitter value of 6 in 1X operation can display a jitter value of 14 when enabled for 2X operation. As indicated in Table 29, these values are unacceptable. Canopy OFDM uses a different modulation scheme and does not display a jitter value.
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  135     12.4 USING LINK EFFICIENCY TO CHECK RECEIVED SIGNAL QUALITY A link test, available in the Link Capacity Test tab of the Tools web page in an AP or BH, provides a more reliable indication of received signal quality, particularly if you launch tests of varying duration. However, a link test interrupts traffic and consumes system capacity, so do not routinely launch link tests across your networks.  12.4.1 Comparing Efficiency in 1X Operation to Efficiency in 2X Operation Efficiency of at least 98 to 100% indicates a high quality signal. Check the signal quality numerous times, at various times of day and on various days of the week (as you checked the RF environment a variety of times by spectrum analysis before placing radios in the area). Efficiency less than 90% in 1X operation or less than 60% in 2X operation indicates a link with problems that require action.  12.4.2 When to Switch from 2X to 1X Operation Based on 60% Link Efficiency In the above latter case (60% in 2X operation), the link experiences worse latency (from packet resends) than it would in 1X operation, but still greater capacity, if the link remains stable at 60% Efficiency. Downlink Efficiency and Uplink Efficiency are measurements produced by running a link test from either the SM or the AP. Examples of what action should be taken based on Efficiency in 2X operation are provided in Table 30. Table 30: Recommended courses of action based on Efficiency in 2X operation Module Types Further Investigation Result Recommended Action Check the General Status tab of the Advantage SM.1 See Checking the Status of 2X Operation on Page 91. Uplink and downlink are both ≥60% Efficiency.2 Rerun link tests. Advantage AP with Advantage SM Rerun link tests. Uplink and downlink are both ≥60% Efficiency. Optionally, re-aim SM, add a reflector, or otherwise mitigate interference. In any case, continue 2X operation up and down.

Uplink and downlink are both ≥60% Efficiency.2 Rerun link tests. Uplink and downlink are both ≥60% Efficiency. Optionally, re-aim SM, add a reflector, or otherwise mitigate interference. In any case, continue 2X operation up and down. Rerun link tests. Results are inconsistent and range from 20% to 80% Efficiency. Monitor the Session Status tab in the Advantage AP. Monitor the Session Status tab in the Advantage AP. Link fluctuates between 2X and 1X operation.3 Optionally, re-aim SM, add a reflector, or otherwise mitigate interference. Then rerun link tests. Rerun link tests. No substantial improvement with consistency is seen. On the General tab of the SM, disable 2X operation. Then rerun link tests. Advantage AP with Canopy SM Rerun link tests. Uplink and downlink are both ≥90% Efficiency. Continue 1X operation up and down. NOTES: 1.  Or check Session Status page of the Advantage AP, where a sum of greater than 7,000,000 bps for the up- and downlink indicates 2X operation up and down (for 2.4- or 5.x-GHz modules. 2.  For throughput to the SM, this is equivalent to 120% Efficiency in 1X operation, with less capacity used at the AP. 3.  This link is problematic.  12.5 CONSIDERING FREQUENCY BAND ALTERNATIVES For 5.2-, 5.4-, and 5.7-GHz modules, 20-MHz wide channels are centered every 5 MHz. For 2.4-GHz modules, 20-MHz wide channels are centered every 2.5 MHz. For Canopy OFDM, the operator can configure center channel frequencies of the 10 MHz channels with a granularity of 0.5 MHz.This allows the operator to customize the channel layout for interoperability where other Canopy equipment is collocated. Cross-band deployment of APs and BH is the recommended alternative (for example, a 5.2-GHz AP collocated with 5.7-GHz BH).  IMPORTANT! In all cases, channel center separation between collocated Canopy FSK modules should be at least 20 MHz for 1X operation and 25 MHz for 2X. For Canopy OFDM, channel center separation between collocated modules should be at least XX MHz for 1X operation, XX for 2 X operation, and XX for 3X operation.
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  137     12.5.1 900-MHz Channels 900-MHz AP Available Channels A 900-MHz AP can operate with its 8-MHz wide channel centered on any of the following frequencies: (All Frequencies in MHz) 906 909 912 915 918 922 907 910 913 916 919 923 908 911 914 917 920 924 900-MHz AP Cluster Recommended Channels Three non-overlapping channels are recommended for use in a 900-MHz AP cluster: (All Frequencies in MHz) 906 915 924  This recommendation allows 9 MHz of separation between channel centers. You can use the Spectrum Analysis feature in an SM, or use a standalone spectrum analyzer, to evaluate the RF environment. In any case, ensure that the 8-MHz wide channels you select do not overlap. 12.5.2 2.4-GHz Channels 2.4-GHz BHM and AP Available Channels A 2.4-GHz BHM or AP can operate with its 20-MHz wide channel centered on any of the following channels, which are separated by only 2.5-MHz increments. (All Frequencies in GHz) 2.4150 2.4275 2.4400 2.4525 2.4175 2.4300 2.4425 2.4550 2.4200 2.4325 2.4450 2.4575 2.4225 2.4350 2.4475  2.4250 2.4375 2.4500   The center channels of adjacent 2.4-GHz APs should be separated by at least 20 MHz. 2.4-GHz AP Cluster Recommended Channels Three non-overlapping channels are recommended for use in a 2.4-GHz AP cluster: (All Frequencies in GHz) 2.4150 2.4350 2.4575  This recommendation allows 20 MHz of separation between one pair of channels and 22.5 MHz between the other pair. You can use the Spectrum Analysis feature in an SM or BHS, or use a standalone spectrum analyzer, to evaluate the RF environment. Where spectrum analysis identifies risk of interference for any of these channels, you can compromise this recommendation as follows: ◦  Select 2.4375 GHz for the middle channel ◦  Select 2.455 GHz for the top channel ◦  Select 2.4175 GHz for the bottom channel

In this frequency band range, the possible sets of three non-overlapping channels are numerous. As many as 11 non-overlapping 20-MHz wide channels are available for 1X operation. Fewer 25-MHz wide channels are available for 2X operation, where this greater separation is recommended for interference avoidance.

Where regulations require you to have Dynamic Frequency Selection (DFS) enabled, analyze the spectrum, then spread your channel selections as evenly as possible throughout this frequency band range, appropriately sharing it with satellite services.   12.5.5 5.4-GHz OFDM Channels Channel selections for the Canopy OFDM AP in the 5.4-GHz frequency band range depend on whether the AP is deployed in cluster.  5.4-GHz BH and Single AP Available  OFDM modules are configured by the operator for channels, using the Configuration => Custom Frequencies page. The channels of adjacent APs should be separated by at least XX MHz, especially for APs to take advantage of 3X operation. 5.4-GHz AP Cluster Recommended Channels The fully populated cluster may be configured  for two or four channels. If configured for two channels, each channel is reused by the module that is mounted 180° opposed. The modules are pre-configured with channels which can be used as a starting point for selecting the two or four for use in a full 4 AP cluster. 12.5.6 5.7-GHz Channels Channel selections for the AP in the 5.7-GHz frequency band range depend on whether the AP is deployed in cluster.  5.7-GHz BH and Single AP Available Channels A BH or a single 5.7-GHz AP enabled for frequencies can operate in the following channels, which are separated by 5-MHz increments.

However,  25 MHz of separation is advised, especially for Advantage APs to take advantage of 2X operation. 5.7-GHz AP Cluster Recommended Channels Six non-overlapping channels are recommended for use in 5.7-GHz AP clusters: (All Frequencies in GHz) 5.735 5.775 5.815 5.755 5.795 5.835  The fully populated cluster requires only three channels, each reused by the module that is mounted 180° offset. The six channels above are also used for backhaul point-to-point links. As noted above, a 5.7-GHz AP can operate on a frequency as high as 5.840 GHz. Where engineering plans allow, this frequency can be used to provide an additional 5-MHz separation between AP and BH channels. 12.5.7 Channels Available for PTP 400 and PTP 600 radios Channel selections for radios in the PTP400 and PTP 600 series are quoted in the user guides that are dedicated to those products. However, these units dynamically change channels when the signal substantially degrades. Since the available channels are in the 5.4- and 5.7-GHz frequency band ranges, carefully consider the potential effects of deploying these products into an environment where traffic in this range pre-exists. 12.5.8 Example Channel Plans for AP Clusters Examples for assignment of frequency channels and sector IDs are provided in the following tables. Each frequency is reused on the sector that is at a 180° offset. The entry in the Symbol column of each table refers to the layout in Figure 32 on Page 142.

(Perform spectrum analysis.) ◦  whether available mounting positions exist near the lowest elevation that satisfies line of site, coverage, and other link criteria. ◦  whether you will always have the right to decide who climbs the tower to install and maintain your equipment, and whether that person or company can climb at any hour of any day. ◦  whether you will have collaborative rights and veto power to prevent interference to your equipment from wireless equipment that is installed at the site in the future. ◦  whether a pre-existing grounding system (path to Protective Earth  ) exists, and what is required to establish a path to it. ◦  who is permitted to run any indoor lengths of cable. 12.6.3 Assuring the Essentials In the 2.4-, 5.2-, 5.4-, and 5.7-GHz frequency band ranges, an unobstructed line of sight (LOS) must exist and be maintainable between the radios that are involved in each link. Line of Sight (LOS) Link In these ranges, a line of sight link is both ◦  an unobstructed straight line from radio to radio. ◦  an unobstructed zone surrounding that straight line. Fresnel Zone Clearance An unobstructed line of sight is important, but is not the only determinant of adequate placement.  Even where the path has a clear line of sight, obstructions such as terrain, vegetation, metal roofs, or cars may penetrate the Fresnel zone and cause signal loss. Figure 33 illustrates an ideal Fresnel zone.   Transmitteror Amplifier receivertransmitterFresnel zone
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  145     Figure 33: Fresnel zone  FresnelZoneCalcPage.xls calculates the Fresnel zone clearance that is required between the visual line of sight and the top of an obstruction that would protrude into the link path. Non-Line of Sight (NLOS) Link The Canopy 900-MHz modules have a line of sight (LOS) range of 40 miles (more than 64 km) and greater non-line of sight (NLOS) range than Canopy modules of other frequency bands. NLOS range depends on RF considerations such as foliage, topography, obstructions. 12.6.4 Finding the Expected Coverage Area The transmitted beam in the vertical dimension covers more area beyond than in front of the beam center. BeamwidthRadiiCalcPage.xls calculates the radii of the beam coverage area. 12.6.5 Clearing the Radio Horizon Because the surface of the earth is curved, higher module elevations are required for greater link distances. This effect can be critical to link connectivity in link spans that are greater than 8 miles (12 km). AntennaElevationCalcPage.xls calculates the minimum antenna elevation for these cases, presuming no landscape elevation difference from one end of the link to the other. 12.6.6 Calculating the Aim Angles The appropriate angle of AP downward tilt is derived from both the distance between transmitter and receiver and the difference in their elevations. DowntiltCalcPage.xls calculates this angle. The proper angle of tilt can be calculated as a factor of both the difference in elevation and the distance that the link spans. Even in this case, a plumb line and a protractor can be helpful to ensure the proper tilt. This tilt is typically minimal. The number of degrees to offset (from vertical) the mounting hardware leg of the support tube is equal to the angle of elevation from the lower module to the higher module (<B in the example provided in Figure 34).   LEGEND b  Angle of elevation. B  Vertical difference in elevation. A  Horizontal distance between modules.  Figure 34: Variables for calculating angle of elevation (and depression)
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  146      Calculating the Angle of Elevation To use metric units to find the angle of elevation, use the following formula: tan b  =  B1000A where B is expressed in meters A is expressed in kilometers. To use English standard units to find the angle of elevation, use the following formula: tan b  =  B5280A where B is expressed in feet A is expressed in miles. The angle of depression from the higher module is identical to the angle of elevation from the lower module. 12.7 COLLOCATING CANOPY MODULES A BH and an AP or AP cluster on the same tower require a CMM. The CMM properly synchronizes the transmit start times of all Canopy modules to prevent interference and desensing of the modules. At closer distances without sync from a CMM, the frame structures cause self interference. Furthermore, a BH and an AP on the same tower require that the effects of their differing receive start times be mitigated by either ◦  100 vertical feet (30 meters) or more and as much spectral separation as possible within the same frequency band range. ◦  the use of the frame calculator to tune the Downlink Data parameter in each, so that the receive start time in each is the same. See Using the Frame Calculator Tool (All) on Page 438.  Canopy APs and a BHS can be collocated at the same site only if they operate in different frequency band ranges. Where a single BH air link is insufficient to cover the distance from an AP cluster to your point of presence (POP), you can deploy two BHSs, connected to one another by Ethernet, on a tower that is between a BHM collocated with the AP cluster and another BHM collocated with the POP. This deployment is illustrated in Figure 35.

The constraints for collocated modules in the same frequency band range are to avoid self-interference that would occur between them. Specifically, unless the uplink and downlink data percentages match, intervals exist when one is transmitting while the other is receiving, such that the receiving module cannot receive the signal from the far end.  The interference is less a problem during low throughput periods and intolerable during high. Typically, during low throughput periods, sufficient time exists for the far end to retransmit packets lost because of interference from the collocated module. 12.8 DEPLOYING A REMOTE AP In cases where the subscriber population is widely distributed, or conditions such as geography restrict network deployment, you can add a Remote AP to  ◦  provide high-throughput service to near LoS business subscribers. ◦  reach around obstructions or penetrate foliage with non-LoS throughput.  ◦  reach new, especially widely distributed, residential subscribers with broadband service. ◦  pass sync to an additional RF hop.  In the remote AP configuration, a Canopy AP is collocated with a Canopy SM. The remote AP distributes the signal over the last mile to SMs that are logically behind the collocated SM. A remote AP deployment is illustrated in Figure 36.

Base your selection of frequency band ranges on regulatory restrictions, environmental conditions, and throughput requirements.    IMPORTANT! Each relay hop (additional daisy-chained remote AP) adds latency to the link as follows:  ◦  approximately 6 msec where hardware scheduling is enabled. ◦ approximately 15 msec where software scheduling is enabled.  12.8.1 Remote AP Performance The performance of a remote AP is identical to the AP performance in cluster. Throughputs, ranges, and patch antenna coverage are identical. Canopy Advantage and Canopy modules can be deployed in tandem in the same sector to meet customer bandwidth demands. As with all equipment operating in the unlicensed spectrum, Motorola strongly recommends that you perform site surveys before you add network elements. These will indicate that spectrum is available in the area where you want to grow. Keep in mind that ◦  non-LoS ranges heavily depend on environmental conditions.  ◦  in most regions, not all frequencies are available.  ◦  your deployments must be consistent with local regulatory restrictions. 12.8.2 Example Use Case for RF Obstructions A remote AP can be used to provide last-mile access to a community where RF obstructions prevent SMs from communicating with the higher-level AP in cluster. For example, you may be able to use 900 MHz for the last mile between a remote AP and the outlying SMs where these subscribers cannot form good links to a higher-level 2.4-GHz AP. In this case, the short range of the 900-MHz remote AP is sufficient, and the ability of

One of the SMs in the sector is wired to a 900-MHz remote AP, which provides NLoS sustained aggregate throughput4 of  ◦  4 Mbps to 900-MHz SMs up to 2 miles away in the sector. ◦  2 Mbps to 900-MHz SMs between 2 and 4 miles away in the sector. 12.8.3 Example Use Case for Passing Sync All Canopy radios support the remote AP functionality. The BHS and the SM can reliably pass the sync pulse, and the BHM and AP can reliably receive it.

The sync is passed in a cable that connects Pins 1 and 6 of the RJ-11 timing ports of the two modules. When you connect modules in this way, you must also adjust configuration parameters to ensure that ◦  the AP is set to properly receive sync. ◦  the SM will not propagate sync to the AP if the SM itself ceases to receive sync.  Perform Procedure 35: Extending network sync on Page 367. 12.8.4 Physical Connections Involving the Remote AP The SM to which you wire a remote AP can be either an SM that serves a customer or an SM that simply serves as a relay. Where the SM serves a customer, wire the remote AP to the SM as shown in Figure 38.  Figure 38: Remote AP wired to SM that also serves a customer  Where the SM simply serves as a relay, you must use a straight-through RJ-45  female-to-female coupler, and wire the SM to the remote AP as shown in Figure 39.

For 2.4-GHz modules, 20-MHz wide channels are centered every 2.5 MHz. For 5.4-GHz OFDM modules, 10-MHz wide channels can be centered every 0.5 MHz. This allows you to customize the channel layout for interoperability where other Canopy equipment is collocated, as well as select channels with the least background interference level.  CAUTION! Regardless of whether 2.4-, 5.2-,  5.4-, or 5.7-GHz modules are deployed, channel separation between modules should be at least 20 MHz for 1X operation or 25 MHz for 2X.  Physical Proximity A BH and an AP on the same tower require a CMM. The CMM properly synchronizes the transmit start times of all Canopy modules to prevent interference and desensing of the modules. At closer distances without sync from a CMM, the frame structures cause self interference.

Issue 2, November 2007  Draft 5 for Regulatory Review  152     Furthermore, a BH and an AP on the same tower require that the effects of their differing receive start times be mitigated by either ◦  100 vertical feet (30 meters) or more and as much spectral separation as possible within the same frequency band range. ◦  the use of the frame calculator to tune the Downlink Data % parameter in each, so that the receive start time in each is the same. See Using the Frame Calculator Tool (All) on Page 438. Spectrum Analysis (Not available on Canopy OFDM modules) You can use an SM or BHS as a spectrum analyzer. See Mapping RF Neighbor Frequencies on Page 131. Through a toggle of the Device Type parameter, you can temporarily transform an AP into an SM to use it as a spectrum analyzer.  Power Reduction to Mitigate Interference Where any module (SM, AP, BH timing master, or BH timing slave) is close enough to another module that self-interference is possible, you can set the SM to operate at less than full power. To do so, perform the following steps.  CAUTION! Too low a setting of the Transmitter Output Power parameter can cause a link to a distant module to drop. A link that drops for this reason requires Ethernet access to the GUI to re-establish the link.  Procedure 3: Reducing transmitter output power 1.  Access the Radio tab of the module. 2.  In the Transmitter Output Power parameter, reduce the setting. 3.  Click Save Changes. 4.  Click Reboot. 5.  Access the Session Status tab in the Home web page of the SM. 6.  Assess whether the link achieves good Power Level and Jitter values. NOTE: The received Power Level is shown in dBm and should be maximized. Jitter should be minimized. However, better/lower jitter should be favored over better/higher dBm. For historical reasons, RSSI is also shown and is the unitless measure of power. The best practice is to use Power Level and ignore RSSI, which implies more accuracy and precision than is inherent in its measurement. 7.  Access the Link Capacity Test tab in the Tools web page of the module. 8.

Be especially cognitive of these symptoms for 900-MHz links. Where you see these symptoms, attempt the following remedies: ◦  Adjust the position of the SM. ◦  Deploy a band-pass filter at the AP. ◦  Consider adding a remote AP closer to the affected SMs. (See Deploying a Remote AP on Page 147.)  Certain other actions, which may seem to be potential remedies, do not resolve high noise level problems: ◦ Do not deploy an omnidirectional antenna. ◦ Do not set the antenna gain above the regulated level. ◦ Do not deploy a band-pass filter in the expectation that this can mitigate co-channel interference.
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  155     13 ENGINEERING YOUR IP COMMUNICATIONS 13.1 UNDERSTANDING ADDRESSES A basic understanding of Internet Protocol (IP) address and subnet mask concepts is required for engineering your IP network. 13.1.1 IP Address The IP address is a 32-bit binary number that has four parts (octets). This set of four octets has two segments, depending on the class of IP address. The first segment identifies the network. The second identifies the hosts or devices on the network. The subnet mask marks a boundary between these two sub-addresses.  13.2 DYNAMIC OR STATIC ADDRESSING For any computer to communicate with a Canopy module, the computer must be configured to either ◦  use DHCP (Dynamic Host Configuration Protocol). In this case, when not connected to the network, the computer derives an IP address on the 169.254 network within two minutes. ◦  have an assigned static IP address (for example, 169.254.1.5) on the 169.254 network.   IMPORTANT! If an IP address that is set in the module is not the 169.254.x.x network address, then the network operator must assign the computer a static IP address in the same subnet.  13.2.1 When a DHCP Server is Not Found To operate on a network, a computer requires an IP address, a subnet mask, and possibly a gateway address. Either a DHCP server automatically assigns this configuration information to a computer on a network or an operator must input these items.  When a computer is brought on line and a DHCP server is not accessible (such as when the server is down or the computer is not plugged into the network), Microsoft and Apple operating systems default to an IP address of 169.254.x.x and a subnet mask of 255.255.0.0 (169.254/16, where /16 indicates that the first 16 bits of the address range are identical among all members of the subnet).

Issue 2, November 2007  Draft 5 for Regulatory Review  156     13.3  NETWORK ADDRESS TRANSLATION (NAT) 13.3.1 NAT, DHCP Server, DHCP Client, and DMZ in SM The Canopy system provides NAT (network address translation) for SMs in the following combinations of NAT and DHCP (Dynamic Host Configuration Protocol): ◦  NAT Disabled (as in earlier releases) ◦  NAT with DHCP Client and DHCP Server ◦  NAT with DHCP Client ◦  NAT with DHCP Server ◦  NAT without DHCP NAT NAT isolates devices connected to the Ethernet/wired side of an SM from being seen directly from the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic (separate from its address for management), terminates transport traffic, and allows you to assign a range of IP addresses to devices that are connected to the Ethernet/wired side of the SM.  In the Canopy system, NAT supports many protocols, including HTTP, ICMP (Internet Control Message Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN) implementation, L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) is supported, but PPTP (Point to Point Tunneling Protocol) is not supported. See NAT and VPNs on Page 161. DHCP DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP addresses, and allows modules to be moved to a different network within the Canopy system. In conjunction with the NAT features, each SM provides ◦  a DHCP server that assigns IP addresses to computers connected to the SM by Ethernet protocol. ◦  a DHCP client that receives an IP address for the SM from a network DHCP server. DMZ In conjunction with the NAT features, a DMZ (demilitarized zone) allows the assignment of one IP address behind the SM for a device to logically exist outside the firewall and receive network traffic. The first three octets of this IP address must be identical to the first three octets of the NAT private IP address.

Figure 44: NAT without DHCP implementation  13.3.2 NAT and VPNs VPN technology provides the benefits of a private network during communication over a public network. One typical use of a VPN is to connect remote employees, who are at home or in a different city, to their corporate network over the public Internet. Any of several VPN implementation schemes is possible. By design, NAT translates or changes addresses, and thus interferes with a VPN that is not specifically supported by a given NAT implementation. With NAT enabled, SMs support L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) VPNs, but do not support PPTP (Point to Point Tunneling Protocol) VPNs. With NAT disabled, SMs support all types of VPNs. 13.4 DEVELOPING AN IP ADDRESSING SCHEME Canopy network elements are accessed through IP Version 4 (IPv4) addressing.  A proper IP addressing method is critical to the operation and security of a Canopy network.
Release 8    Planning Guide                  March 200                  Through Software Release 6.   Issue 2, November 2007  Draft 5 for Regulatory Review  162     Each Canopy module requires an IP address on the network. This IP address is for only management purposes. For security, you should either ◦  assign an unroutable IP address. ◦  assign a routable IP address only if a firewall is present to protect the module.   You will assign IP addresses to computers and network components by either static or dynamic IP addressing. You will also assign the appropriate subnet mask and network gateway to each module.  13.4.1 Address Resolution Protocol As previously stated, the MAC address identifies a Canopy module in ◦  communications between modules. ◦  the data that modules store about each other. ◦  the data that BAM or Prizm applies to manage authentication and bandwidth.  The IP address is essential for data delivery through a router interface. Address Resolution Protocol (ARP) correlates MAC addresses to IP addresses. For communications to outside the network segment, ARP reads the network gateway address of the router and translates it into the MAC address of the router. Then the communication is sent to MAC address (physical network interface card) of the router. For each router between the sending module and the destination, this sequence applies. The ARP correlation is stored until the ARP cache times out. 13.4.2 Allocating Subnets The subnet mask is a 32-bit binary number that filters the IP address. Where a subnet mask contains a bit set to 1, the corresponding bit in the IP address is part of the network address.    Example IP Address and Subnet Mask In Figure 45, the first 16 bits of the 32-bit IP address identify the network:  Octet 1 Octet 2 Octet 3 Octet 4 IP address 169.254.1.1 10101001 11111110 00000001 00000001 Subnet mask 255.255.0.0 11111111 11111111 00000000 00000000 Figure 45: Example of IP address in Class B subnet  In this example, the network address is 169.254, and 216 (65,536) hosts are addressable.  13.4.3 Selecting Non-routable IP Addresses The factory default assignments for Canopy network elements are ◦  unique MAC address ◦  IP address of 169.254.1.1, except for an OFDM series BHM, whose IP address is 169.254.1.2 by default ◦  subnet mask of 255.255.0.0

Issue 2, November 2007  Draft 5 for Regulatory Review  163     ◦  network gateway address of 169.254.0.0  For each Canopy radio and CMMmicro, assign an IP address that is both consistent with the IP addressing plan for your network and cannot be accessed from the Internet. IP addresses within the following ranges are not routable from the Internet, regardless of whether a firewall is configured: ◦  10.0.0.0 – 10.255.255.255 ◦  172.16.0.0 – 172.31.255.255 ◦  192.168.0.0 – 192.168.255.255  You can also assign a subnet mask and network gateway for each CMMmicro.

Issue 2, November 2007  Draft 5 for Regulatory Review  165     14 ENGINEERING VLANS Canopy radios support VLAN functionality as defined in the 802.1Q (Virtual LANs) specification, except for the following aspects of that specification: ◦  the following protocols: −  Generic Attribute Registration Protocol (GARP) GARV −  Spanning Tree Protocol (STP) −  Multiple Spanning Tree Protocol (MSTP) −  GARP Multicast Registration Protocol (GMRP) ◦  priority encoding (802.1P) before Release 7.0 ◦  embedded source routing (ERIF) in the 802.1Q header ◦  multicast pruning ◦  flooding unknown unicast frames in the downlink  As an additional exception, the Canopy AP does not flood downward the unknown unicast frames to the Canopy SM. A VLAN configuration in Layer 2 establishes a logical group within the network. Each computer in the VLAN, regardless of initial or eventual physical location, has access to the same data. For the network operator, this provides flexibility in network segmentation, simpler management, and enhanced security.  14.1 SM MEMBERSHIP IN VLANS With the supported VLAN functionality, Canopy radios determine bridge forwarding on the basis of not only the destination MAC address, but also the VLAN ID of the destination. This provides flexibility in how SMs are used: ◦  Each SM can be a member in its own VLAN. ◦  Each SM can be in its own broadcast domain, such that only the radios that are members of the VLAN can see broadcast and multicast traffic to and from the SM. ◦  The network operator can define a work group of SMs, regardless of the AP(s) to which they register.  Canopy point-to-multipoint modules provide the VLAN frame filters that are described in Table 36.

When the high-priority channel is enabled on an SM, regardless of whether VLAN is enabled on the AP for the sector, packets received with a priority of 4 through 7 in the 802.1p field are forwarded onto the high-priority channel. VLAN settings in a Canopy module can also cause the module to convert received non-VLAN packets into VLAN packets. In this case, the 802.1p priority in packets leaving the module is set to the priority established by the DiffServ configuration. If you enable VLAN, immediately monitor traffic to ensure that the results are as desired. For example, high-priority traffic may block low-priority. For more information on the Canopy high priority channel, see High-priority Bandwidth on Page 86.

Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  169     15 AVOIDING HAZARDS Use simple precautions to protect staff and equipment. Hazards include exposure to RF waves, lightning strikes, and power surges. This section specifically recommends actions to abate these hazards.  15.1 EXPOSURE SEPARATION DISTANCES To protect from overexposure to RF energy, install Canopy radios so as to provide and maintain the minimum separation distances from all persons shown in Table 37.  Table 37: Exposure separation distances Module Type Separation Distance from Persons Canopy Module, FSK or OFDM At least 20 cm (approx 8 in) Canopy Module with Reflector Dish At least 1.5 m (approx 60 in or 5 ft) Canopy Module with LENS At least 0.5 m (approx 20 in) Antenna of connectorized 5.7 GHz AP At least 30 cm (approx 12 in) Antenna of connectorized or integrated 900 MHz module At least 60 sm (24 in) Indoor 900 MHz SM At least 10 cm (4 in)  Section 15.1.1 and Table 38 give details and discussion of the associated calculations. 15.1.1 Details of Exposure Separation Distances Calculations and Power Compliance Margins Limits and guidelines for RF exposure come from: ◦  US FCC limits for the general population. See the FCC web site at http://www.fcc.gov, and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of Federal Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC OET Bulletin 65.  ◦  Health Canada limits for the general population. See the Health Canada web site at http://www.hc-sc.gc.ca/rpb and Safety Code 6. ◦  ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the general public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields.  The applicable power density exposure limits from the documents referenced above are   ◦  6 W/m2 for RF energy in the 900-MHz frequency band in the US and Canada. ◦  10 W/m2 for RF energy in the 2.4-, 5.2-, 5.4-, and 5.7-GHz frequency bands.  Peak power density in the far field of a radio frequency point source is calculated as follows:

They are also chosen so that a given item (bare module, reflector, or LENS) always has the same distance, regardless of frequency band, to simplify following exposure distances in the field. These are conservative distances: ◦  They are along the beam direction (the direction of greatest energy). Exposure to the sides and back of the module will be significantly less. ◦  They meet sustained exposure limits for the general population (not just short term occupational exposure limits), with considerable margin. ◦  In the reflector cases, the calculated compliance distance d is greatly overestimated because the far-field equation models the reflector as a point source and neglects the physical dimension of the reflector.  15.2 GROUNDING CANOPY EQUIPMENT Effective lightning protection diverts lightning current safely to ground, Protective Earth (PE)  . It neither attracts nor prevents lightning strikes.  WARNING! Lightning damage is not covered under the Canopy warranty. The recommendations in Canopy guides give the installer the knowledge to protect the installation from the harmful effects of ESD and lightning. These recommendation must be thoroughly and correctly performed. However, complete protection is neither implied or possible. 15.2.1 Grounding Infrastructure Equipment To protect both your staff and your infrastructure equipment, implement lightning protection as follows: ◦  Observe all local and national codes that apply to grounding for lightning protection. ◦  Before you install your Canopy modules, perform the following steps: −  Engage a grounding professional if you need to do so.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  172     −  Install lightning arrestors to transport lightning strikes away from equipment. For example, install a lightning rod on a tower leg other than the leg to which you mount your module. −  Connect your lightning rod to ground. −  Use a Canopy 600SS Surge Suppressor on the Ethernet cable where the cable enters any structure. (Instructions for installing a Canopy 600SS Surge Suppressor are provided in Procedure 28 on Page 344.) ◦  Install your modules at least 2 feet (0.6 meters) below the tallest point on the tower, pole, or roof. 15.2.2 Grounding SMs This section provides lightning protection guidelines for SMs to satisfy the National Electrical Code (NEC) of the United States. The requirements of the NEC focus on the safety aspects of electrical shock to personnel and on minimizing the risk of fire at a dwelling. The NEC does not address the survivability of electronic products that are exposed to lightning surges. The statistical incidence of current levels from lightning strikes is summarized in  Table 39. Table 39: Statistical incidence of current from lightning strikes Percentage of all strikes Peak Current (amps)   <2    >140,000   25      >35,000 >50      >20,000 >80        >8,500   At peak, more than one-half of all surges due to direct lightning strikes exceed 20,000 amps. However, only one-quarter exceed 35,000 amps, and less than two percent exceed 140,000 amps. Thus, the recommended Surge Suppressor (300SS) provides a degree of lightning protection to electronic devices inside a dwelling. Summary of Grounding Recommendations Motorola recommends that you ground each SM as follows: ◦  Extend the SM mounting bracket extend to the top of the SM or higher. ◦  Ground the SM mounting bracket via a 10-AWG (6 mm2) copper wire connected by the most direct path either to an eight foot-deep ground rod or to the ground bonding point of the AC power service utility entry. This provides the best assurance that  −  lightning takes the ground wire route −  the ground wire does not fuse open −  your grounding system complies with NEC 810-15.  ◦  Ground the Canopy Surge Suppressor 300SS or 600SS ground lug to the same ground bonding point as above, using at least a 10-AWG (6 mm2) copper wire. This provides the best assurance that your grounding system complies with  NEC 810-21.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  173     Grounding Scheme The proper overall antenna grounding scheme per the NEC is illustrated in Figure 128 on Page 345. In most television antenna or dish installations, a coaxial cable connects the outdoor electronics with the indoor electronics. To meet NEC 810-20, one typically uses a coaxial cable feed-through block that connects the outdoor coax to the indoor coax and also has a screw for attaching a ground wire. This effectively grounds the outer shield of the coax. The block should be mounted on the outside of the building near the AC main panel such that the ground wire of the block can be bonded to the primary grounding electrode system of the structure. For residential installs, in most cases an outdoor rated unshielded twisted pair (UTP) cable is sufficient. To comply with the NEC, Motorola provides the antenna discharge unit, 300SS or 600SS, for each conductor of the cable. The surge suppressor must be  ◦  positioned −  outside the building. −  as near as practicable to the power service entry panel of the building and attached to the AC main power ground electrode, or attached to a grounded water pipe.5  −  far from combustible material. ◦  grounded in accordance with NEC 810-21, with the grounding wire attached to the screw terminal.  The metal structural elements of the antenna mast also require a separate grounding conductor. Section 810-15 of the NEC states:  Masts and metal structures supporting antennas shall be grounded in accordance with Section 810-21. As shown in Figure 128 on Page 345, the Motorola recommendation for grounding the metal structural element of the Canopy mounting bracket (SMMB1) is to route the grounding wire from the SMMB1 down to the same ground attachment point as is used for the 300SS discharge unit. Use 10-AWG (6 mm2) Copper Grounding Wire According to NEC 810-21 3(h), either a 16-AWG copper clad steel wire or a 10-AWG copper wire may be used. This specification appears to be based on mechanical strength considerations and not on lightning current handling capabilities.  For example, analysis shows that the two wire types are not equivalent when carrying a lightning surge that has a 1-microsecond rise by 65-microsecond fall:  ◦  The 16-AWG copper clad steel wire has a peak fusing current of 35,000 amps and can carry 21,000 amps peak, at a temperature just below the ignition point for paper (454° F or 234° C).  ◦  The 10-AWG copper wire has a peak fusing current of 220,000 amps and can carry 133,000 amps peak, at the same temperature.                                                         5 It is insufficient to merely use the green wire ground in a duplex electrical outlet box for grounding of the antenna discharge unit.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  174     Based on the electrical/thermal analysis of these wires, Motorola recommends 10-AWG copper wire for all grounding conductors. Although roughly double the cost of 16-AWG copper clad steel wire, 10-AWG copper wire handles six times the surge current from lightning. Shielding is not Grounding In part, NEC 810-21 states: A lightning arrester is not required if the lead-in conductors are enclosed in a continuous metal shield, such as rigid or intermediate metal conduit, electrical metallic tubing, or any metal raceway or metal-shielded cable that is effectively grounded. A lightning discharge will take the path of lower impedance and jump from the lead-in conductors to the metal raceway or shield rather than take the path through the antenna coil of the receiver. However, Motorola does not recommend relying on shielded twisted pair cable for lightning protection for the following reasons: ◦  Braid-shielded 10Base-T cable is uncommon, if existent, and may be unsuitable anyway. ◦  At a cost of about two-thirds more than 10-AWG copper UTP, CAT 5  100Base-TX foil-shielded twisted pair (FTP) cable provides a 24-AWG drain wire. If this wire melts open during a lightning surge, then the current may follow the twisted pair into the building.  More than 80 percent of all direct lightning strikes have current that exceeds 8,500 amps (see Table 39 on Page 172). A 24-AWG copper wire melts open at 8,500 amps from a surge that has a 1-microsecond by 70-microsecond waveform. Hence, reliance on 24-AWG drain wire to comply with the intent of NEC 810-21 is questionable. Shielded twisted pair cable may be useful for mitigation of interference in some circumstances, but installing surge suppressors and implementing the ground recommendations constitute the most effective mitigation against lightning damage.

If you are uncertain of code requirements, engage the services of a licensed electrician. 15.4 PROTECTING CABLES AND CONNECTIONS Cables that move in the wind can be damaged, impart vibrations to the connected device, or both. At installation time, prevent these problems by securing all cables with cable ties, cleats, or PVC tape.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  175     Over time, moisture can cause a cable connector to fail. You can prevent this problem by ◦  using cables that are filled with a dielectric gel or grease. ◦  including a drip loop where the cable approach to the module (typically a CMM2 or CMMmicro) is from above. ◦  wrapping the cable with weather-resistant tape.  On a module with an external antenna, use accepted industry practices to wrap the connector to prevent water ingress. Although the male and female N-type connectors form a gas-tight seal with each other, the point where the cable enters each connector can allow water ingress and eventual corrosion. Wrapping and sealing is critical to long-term reliability of the connection.  Possible sources of material to seal that point include ◦  the antenna manufacturer (material may have been provided in the package with the antenna). ◦  Universal Electronics (whose web site is http://www.coaxseal.com), who markets a weather-tight wrap named Coax-Seal.  Perform the following steps to wrap the cable. Procedure 4: Wrapping the cable 1.  Start the wrap on the cable 0.5 to 2 inches (about 1.5 to 5 cm) from the connection. 2.  Wrap the cable to a point 0.5 to 2 inches (about 1.5 to 5 cm) above the connection.  3.  Squeeze the wrap to compress and remove any trapped air.  4.  Wrap premium vinyl electrical tape over the first wrap where desired for abrasion resistance or appearance. 5.  Tie the cable to minimize sway from wind. =========================== end of procedure ======================
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  177     16 TESTING THE COMPONENTS The best practice is to connect all components—BHs, APs, GPS antenna, and CMM2 or CMMmicro—in a test setting and initially configure and verify them before deploying them to an installation. In this way, any configuration issues are worked out before going on-site, on a tower, in the weather, where the discovery of configuration issues or marginal hardware is more problematic and work-flow affecting. 16.1 UNPACKING COMPONENTS When you receive Canopy products, carefully inspect all shipping boxes for signs of damage. If you find damage, immediately notify the transportation company. As you unpack the equipment, verify that all the components that you ordered have arrived. Save all the packing materials to use later, as you transport the equipment to and from installation sites. 16.2 CONFIGURING FOR TEST You can use either of two methods to configure an AP or BHM: ◦  Use the Quick Start feature of the product. For more information on Quick Start, see Quick Start Page of the AP on Page 185. ◦  Manually set each parameter.  After you change configuration parameters on a GUI web page: 1.  Before you leave a web page, click the Save button to save the change(s). 2.  After making change(s) on multiple web pages, click the Reboot button to reboot the module and implement  the change(s). 16.2.1 Configuring the Computing Device for Test If your computer is configured for Dynamic Host Configuration Protocol (DHCP), disconnect the computer from the network. If your computer is instead configured for static IP addressing ◦  set the static address in the 169.254 network ◦  set the subnet mask to 255.255.0.0.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  178     16.2.2 Default Module Configuration From the factory, the Canopy AP, SM, and BH are all configured to not transmit on any frequency. This configuration ensures that you do not accidentally turn on an unsynchronized module. Site synchronization of modules is required because ◦  Canopy modules −  cannot transmit and receive signals at the same time. −  use TDD (Time Division Duplexing) to distribute signal access of the downlink and uplink frames.  ◦  when one module transmits while an unintended module nearby receives signal, the transmitting module may interfere with or desense the receiving module. In this context, interference is self-interference (within the same Canopy network). 16.2.3 Component Layout As shown in Figure 46, the base cover of the module snaps off when you depress a lever on the back of the base cover. This exposes the Ethernet and GPS sync connectors and diagnostic LEDs.

Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  182     16.2.7 Standards for Wiring Canopy modules automatically sense whether the Ethernet cable in a connection is wired as straight-through or crossover. You may use either straight-through or crossover cable to connect a network interface card (NIC), hub, router, or switch to these modules. For a straight-through cable, use the EIA/TIA-568B wire color-code standard on both ends. For a crossover cable, use the EIA/TIA-568B wire color-code standard on one end, and the EIA/TIA-568A wire color-code standard on the other end. Where you use the Canopy AC wall adapter ◦  the power supply output is +24 VDC. ◦  the power input to the SM is +11.5 VDC to +30 VDC.  ◦  the maximum Ethernet cable run is 328 feet (100 meters). 16.2.8 Best Practices for Cabling The following practices are essential to the reliability and longevity of cabled connections: ◦  Use only shielded cables to resist interference. ◦  For vertical runs, provide cable support and strain relief. ◦  Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermal expansion and contraction and to facilitate terminating the cable again when needed. ◦  Include a drip loop to shed water so that most of the water does not reach the connector at the device. ◦  Properly crimp all connectors. ◦  Use dielectric grease on all connectors to resist corrosion. ◦  Use only shielded connectors to resist interference and corrosion. 16.2.9 Recommended Tools for Wiring Connectors The following tools may be needed for cabling the AP: ◦  RJ-11 crimping tool ◦  RJ-45 crimping tool ◦  electrician scissors ◦  wire cutters ◦  cable testing device. 16.2.10 Wiring Connectors The following diagrams correlate pins to wire colors and illustrate crossovers where applicable. Location of Pin 1 Pin 1, relative to the lock tab on the connector of a straight-through cable is located as shown below.

Unless you save a configuration and reboot the AP after you save the configuration, none of the changes are effected. 16.3.2 Time Tab of the AP To proceed with the test setup, click the Configuration link on the left side of the General Status tab. When the AP responds by opening the Configuration page to the General tab, click the Time tab. An example of this tab is displayed in Figure 57.   Figure 57: Time tab of AP, example  To have each log in the AP correlated to a meaningful time and date, either a reliable network element must pass time and date to the AP or you must set the time and date whenever a power cycle of the AP has occurred. A network element passes time and date in any of the following scenarios: ◦  A connected CMM2 passes time and date (GPS time and date, if received).  ◦  A connected CMMmicro passes the time and date (GPS time and date, if received), but only if both the CMMmicro is operating on CMMmicro Release 2.1 or later release. (These releases include an NTP server functionality.) ◦  A separate NTP server is addressable from the AP.  If the AP should obtain time and date from either a CMMmicro or a separate NTP server, enter the IP address of the CMMmicro or NTP server on this tab. To force the AP to

Procedure 9: Retrying to establish a point-to-multipoint link 1.  More finely aim the SM or SMs toward the AP. 2.  Recheck the Session Status tab of the AP for the presence of LUIDs. 3.  If still no LUIDs are reported on the Session Status tab, click the Configuration button on the left side of the Home page. RESULT: The AP responds by opening the AP Configuration page. 4.  Click the Radio tab. 5.  Find the Color Code parameter and note the setting. 6.  In the same sequence as you did for the AP directly under Configuring a Point-to-Multipoint Link for Test on Page 184, connect the SM to a computing device and to power. 7.  On the left side of the SM Home page, click the Configuration button.  RESULT: The Configuration page of the SM opens.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  194     8.  Click the Radio tab. 9.  If the transmit frequency of the AP is not selected in the Custom Radio Frequency Scan Selection List parameter, select the frequency that matches. 10.  If the Color Code parameter on this page is not identical to the Color Code parameter you noted from the AP, change one of them so that they match.  11.  At the bottom of the Radio tab for the SM, click the Save Changes button. 12.  Click the Reboot button. 13.  Allow several minutes for the SM to reboot and register to the AP. 14.  Return to the computing device that is connected to the AP. 15.  Recheck the Session Status tab of the AP for the presence of LUIDs. =========================== end of procedure ===========================  The Session Status tab provides information about each SM that has registered to the AP. This information is useful for managing and troubleshooting a Canopy system. All information that you have entered in the Site Name field of the SM displays in the Session Status tab of the linked AP.  The Session Status tab also includes the current active values on each SM (LUID) for MIR, CIR, and VLAN, as well as the source of these values (representing the SM itself, BAM, or the AP and cap, if any—for example, APCAP as shown in Figure 58 above). L indicates a Canopy Lite SM, and D indicates from the device. As an SM registers to the AP, the configuration source that this page displays for the associated LUID may change. After registration, however, the displayed source is stable and can be trusted.  The Session Status tab of the AP provides the following parameters. LUID This field displays the LUID (logical unit ID) of the SM. As each SM registers to the AP, the system assigns an LUID of 2 or a higher unique number to the SM. If an SM loses registration with the AP and then regains registration, the SM will retain the same LUID.   NOTE: The LUID association is lost when a power cycle of the AP occurs. MAC This field displays the MAC address (or electronic serial number) of the SM. State This field displays the current status of the SM as either ◦ IN SESSION to indicate that the SM is currently registered to the AP. ◦ IDLE to indicate that the SM was registered to the AP at one time, but now is not.  This field also indicates whether the encryption scheme in the module is enabled.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  195     Site Name This field indicates the name of the SM. You can assign or change this name on the Configuration web page of the SM. This information is also set into the sysName SNMP MIB-II object and can be polled by an SNMP management server. Software Version This field displays the software release that operates on the SM, the release date and time of the software. Software Boot Version This field indicates the CANOPYBOOT version number. FPGA Version This field displays the version of FPGA that runs on the SM. Session Timeout This field displays the timeout in seconds for management sessions via HTTP, telnet, or ftp access to the SM. 0 indicates that no limit is imposed. AirDelay This field displays the distance of the SM from the AP. To derive the distance in meters, multiply the displayed number by 0.3048. At close distances, the value in this field is unreliable. Session Count This field displays how many sessions the SM has had with the AP. Typically, this is the sum of Reg Count and Re-Reg Count. However, the result of internal calculation may display here as a value that slightly differs from the sum.  If the number of sessions is significantly greater than the number for other SMs, then this may indicate a link problem or an interference problem. Reg Count When an SM makes a registration request, the AP checks its local data to see whether it considers the SM to be already registered. If the AP concludes that the SM is not, then the request increments the value of this field. Re-Reg Count When an SM makes a registration request, the AP checks its local data to see whether it considers the SM to be already registered. If the AP concludes that the SM is not, then the request increments the value of this field. Typically, a Re-Reg is the case where both ◦  an SM attempts to reregister for having lost communication with the AP. ◦  the AP has not yet observed the link to the SM as being down.  A high number in this field is often an indication of link instability or interference problems. RSSI, Jitter, and Power Level (Avg/Last) The Session Status tab shows the received Power Level in dBm and Jitter. Proper alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you should favor lower jitter over higher dBm. For example, if coarse alignment gives an SM a power level of −75 dBm and a jitter measurement of 5, and further refining
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  196     the alignment drops the power level to −78 dBm and the jitter to 2 or 3, use the refined alignment, with the following caveats: ◦  When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with desired jitter between 0 and 4.  ◦  When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with desired jitter between 0 and 9.  The Session Status tab also shows a historical RSSI, a unitless measure of power. Use Power Level and ignore RSSI. RSSI implies more accuracy and precision than is inherent in its measurement. Sustained Uplink Data Rate This field displays the value that is currently in effect for the SM, with the source of that value in parentheses. This is the specified rate at which each SM registered to this AP is replenished with credits for transmission. The configuration source of the value is indicated in parentheses. See  ◦ Maximum Information Rate (MIR) Parameters on Page 84 ◦ Interaction of Burst Allocation and Sustained Data Rate Settings on Page 86 ◦ Setting the Configuration Source on Page 292.

Low Priority Downlink CIR This field displays the value that is currently in effect for the SM, with the source of that value in parentheses. The configuration source of the value is indicated in parentheses. See  ◦ Committed Information Rate on Page 86 ◦ Setting the Configuration Source on Page 292. Rate This field displays whether the high-priority channel is enabled in the SM and the status of 1X or 2X operation in the SM. See Checking the Status of 2X Operation on Page 91. 16.3.4 Beginning the Test of Point-to-Multipoint Links To begin the test of links, perform the following steps: 1.  In the Session Status tab of the AP, note the LUID associated with the MAC address of any SM you wish to involve in the test.  2.  Click the Remote Subscribers tab. 16.3.5 Remote Subscribers Tab of the AP An example of a Remote Subscribers tab is displayed in Figure 59.  Figure 59: Remote Subscribers tab of AP, example
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  198     This tab allows you to view the web pages of registered SMs over the RF link. To view the pages for a selected SM, click its link. The General Status tab of the SM opens. 16.3.6 General Status Tab of the SM An example of the General Status tab of an SM is displayed in Figure 60.  Figure 60: General Status tab of SM, example  The General Status tab provides information on the operation of this SM. This is the tab that opens by default when you access the GUI of the SM. The General Status tab provides the following read-only fields. Device Type  This field indicates the type of the Canopy module. Values include the frequency band of the SM, its module type, and its MAC address. Software Version This field indicates the Canopy system release, the time and date of the release, and whether communications involving the module are secured by DES or AES encryption (see Encrypting Canopy Radio Transmissions on Page 369). If you request technical support, provide the information from this field.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  199     Software BOOT Version This field indicates the version of the CANOPYBOOT file. If you request technical support, provide the information from this field.  Board Type This field indicates the series of hardware. See Designations for Hardware in Radios on Page 365. FPGA Version This field indicates the version of the field-programmable gate array (FPGA) on the module.  When you request technical support, provide the information from this field. Uptime This field indicates how long the module has operated since power was applied. System Time This field provides the current time. Any SM that registers to an AP inherits the system time, which is displayed in this field as GMT (Greenwich Mean Time). Ethernet Interface This field indicates the speed and duplex state of the Ethernet interface to the SM.  Session Status This field displays the following information about the current session: ◦ Scanning indicates that this SM currently cycles through the radio frequencies that are selected in the Radio tab of the Configuration page. ◦ Syncing indicates that this SM currently attempts to receive sync.  ◦ Registering indicates that this SM has sent a registration request message to the AP and has not yet received a response. ◦ Registered indicates that this SM is both −  registered to an AP. −  ready to transmit and receive data packets. ◦ Alignment indicates that this SM is in an aiming mode. See Table 41 on Page 179. Registered AP This field displays the MAC address of the AP to which this SM is registered. RSSI, Power Level, and Jitter The General Status tab shows the received Power Level in dBm and Jitter. Proper alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you should favor lower jitter over higher dBm. For example, if coarse alignment gives an SM a power level of −75 dBm and a jitter measurement of 5, and further refining the alignment drops the power level to −78 dBm and the jitter to 2 or 3, use the refined alignment, with the following caveats: ◦  When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with desired jitter between 0 and 4.
Release 8    Installation and Configuration Guide   Issue 2, November 2007  Draft 5 for Regulatory Review  200     ◦  When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with desired jitter between 0 and 9.  For historical relevance, the General Status tab also shows the RSSI, the unitless measure of power. Use Power Level and ignore RSSI. RSSI implies more accuracy and precision than is inherent in its measurement.   NOTE: Unless the page is set to auto-refresh, the values displayed are from the instant the General Status tab was selected. To keep a current view of the values, refresh the browser screen or set to auto-refresh.  Air Delay This field displays the distance in feet between this SM and the AP. To derive the distance in meters, multiply the value of this parameter by 0.3048. Distances reported as less than 200 feet (61 meters) are unreliable. Site Name This field indicates the name of the physical module. You can assign or change this name in the SNMP tab of the SM Configuration page. This information is also set into the sysName SNMP MIB-II object and can be polled by an SNMP management server.   Site Contact This field indicates contact information for the physical module. You can provide or change this information in the SNMP tab of the SM Configuration page. This information is also set into the sysName SNMP MIB-II object and can be polled by an SNMP management server. Site Location This field indicates site information for the physical module. You can provide or change this information in the SNMP tab of the SM Configuration page. Maximum Throughput This field indicates the limit of aggregate throughput for the SM and is based on the default (factory) limit of the SM and any floating license that is currently assigned to it. 16.3.7 Continuing the Test of Point-to-Multipoint Links To resume the test of links, perform the following steps. Procedure 10: Verifying and recording information from SMs 1.  Verify that the Session Status field of the General Status tab in the SM  indicates REGISTERED.  2.  While you view the General Status tab in the SM, note (or print) the values of the following fields: ◦ Device type ◦ Software Version ◦ Software BOOT Version
