4 REALIZING A WIRELESS BACKHAUL NETWORK
Canopy backhaul modules (BHs) can connect Canopy access point clusters to the point
of presence or be the backbone of a Metro WiFi mesh network. In other applications,
the backhaul modules can be used to provide connectivity for
◦ cell sites, in lieu of leased T1/E1 telecommunications lines.
◦ buildings in corporate or institutional campuses.
◦ remote sites, including temporary sites set up for relief efforts.
These BHs are available in 10- or 20-Mbps modulation rates from the factory. The rate is
distinguished as BH10 or BH20 in the Software Version field of the General Status tab
(in the Home page) of the module GUI.
For these and any other backhaul networks, Table 6 provides a quick reference to
information that you would need to establish and maintain the Canopy wireless backhaul
network.

5 EXPLORING THE SCOPE OF SOLUTIONS
Canopy wireless broadband applications include:
◦ local area network (LAN) extensions
◦ Internet subscriber service
◦ high-bandwidth point-to-point connections
◦ multicast video (for instruction or training, for example)
◦ private branch exchange (PBX) extensions
◦ point-to-multipoint data backhaul
◦ redundant network backup
◦ video surveillance
◦ voice over IP (VoIP)
◦ TDM over Ethernet (for legacy voice and data)
5.1 COMPONENTS
Canopy networks use some or all of the following components. For the components that
provide a graphical user interface (GUI), access to the GUI is through a web browser. In
Release 8 and later, cascading style sheets (CSS) configure the GUI. Thus an operator is
able to customize the GUI by editing these style sheets.
5.1.1 Canopy Access Point Module and Canopy OFDM Access Point Module
The Canopy Access Point (AP) module provides broadband connectivity in a 60° sector.
The Canopy OFDM AP provides broadband connectivity in a 90° sector. Either supports
up to 200 subscribers and 4,096 MAC addresses, which may be directly-connected PCs,
IP appliances, gateways, Subscriber Modules (SMs), and the AP, except that no limit
applies behind subscriber network address translation (NAT) gateways. The AP is
configurable through a web interface. A Canopy AP can only communicate with a Canopy
SM, not also an Advantage SM or a Canopy Lite SM. A Canopy OFDM AP can only
communicate with a Canopy OFDM SM.
5.1.2 Advantage Access Point Module
The Canopy Advantage AP distributes services as broadly as the Canopy AP. However,
the Advantage AP provides greater throughput and less latency. Each tab in the GUI for
Canopy Advantage modules displays the distinctive branding shown in Figure 1.
Figure 1: Canopy Advantage Platform GUI logo
The Advantage AP communicates with all Canopy SMs in its frequency band range:
Canopy SMs, Advantage SMs, and Canopy Lite SMs.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 50
5.1.3 Canopy Access Point Cluster and Canopy OFDM Access Point Cluster
Figure 2: Pole-mounted AP cluster
An AP cluster covers as much as 360°.
The Canopy FSK AP cluster consists of
two to six APs that provide broadband
connectivity to 1,200 or fewer subscribers.
Each AP transmits and receives in a 60°
sector.
The Canopy OFDM AP cluster consists of
two to four APs that provide broadband
connectivity to 800 or fewer subscribers.
Each AP transmits and receives in a 90°
sector.
The variety of available APs, Advantage
APs, and OFDM APs in frequency band
range, power adjustability, and antenna
configuration is shown under Acquiring a
Canopy Demonstration Kit, beginning on
Page 117.
An AP cluster is pictured in Figure 2.
An OFDM AP, showing the antenna in front
and the radio attached to it, is pictured in
Figure 3.
Figure 3: OFDM AP - Antenna and
Radio
5.1.4 Canopy Subscriber Module
The Subscriber Module (SM) is a
customer premises equipment (CPE)
device that provides broadband
services through communication with
an AP. The SM is configurable
through a web interface.
The variety of available SMs,
Advantage SMs, and OFDM SMs in
frequency band range, power
adjustability, and antenna
configuration is shown under
Acquiring a Canopy Demonstration
Kit, beginning on Page 117.
Figure 4: Structure-mounted SM
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 51
A Canopy SM can communicate with
either a Canopy AP or an Advantage
AP. A Canopy OFDM SM can
communicate with only a Canopy
OFDM AP.
An SM mounted directly to a structure
is pictured in Figure 4.
An OFDM SM is shown in Figure 5 in
both front and side views.
Figure 5: OFDM SM, front and side
views
5.1.5 Advantage Subscriber Module
The Canopy Advantage SM provides the same configurability and services as the
Canopy SM. However, in a link with an Advantage AP, the Advantage SM provides
uncapped sustained 2X throughput. See 2X Operation on Page 89. An Advantage SM
can only communicate with an Advantage AP.
5.1.6 Canopy Lite Subscriber Module
Canopy Lite SMs cost less and provide less throughput than regular Canopy SMs. They
support the same radio frequencies, interference tolerance, and product reliability. They
give operators the additional option to serve cost-sensitive customers who want standard
services (web browsing, email, VoIP, and downloads), but do not require the higher
throughput that is available with a regular Canopy SM. Canopy Lite SMs support an
aggregate(uplink plus downlink) throughput of 512 kbps. Through purchased floating
licenses that Prizm manages, they are upgradeable to 1, 2, 4, or 7 Mbps aggregate
throughput. A Canopy Lite SM can communicate with only a Canopy Advantage AP.
A comparison of the Canopy Lite SM to the Canopy SM and Advantage SM is provided in
Table 25 on Page 100.

Issue 2, November 2007 Draft 5 for Regulatory Review 52
5.1.7 900-MHz AP and SM
Canopy 900 MHz AP and SM modules operate at a 3.3 Mbps carrier rate (compared to
10 Mbps for other Canopy frequency bands).
Figure 6: Examples of flat panel antennas with 900-MHz modules
These 900-MHz modules run the same software and provide the same parameters,
network features, and connections as all other Canopy APs and SMs. The physics of
longer-wavelength 900 MHz, the power allowed by regulatory authorities, and the low
required level of Canopy Carrier-to-Interference (C/I) ratio combine to support
◦ line of sight (LOS) range of up to 40 miles (over 64 km)
◦ increased non-line of sight (NLOS) range, depending on RF considerations such
as foliage, topography, and obstructions.
When collocated with a Canopy SM of another frequency band range, the 900-MHz AP
may serve, without a tower or BH, as a remote AP (see Deploying a Remote AP on
Page 147). 900-MHz AP/SM links are logical choices for extending radio networks where
you wish to
◦ add subscriber-handling capacity to a tower that is either
− fully used in the other frequency band ranges.
− not available to any other frequency band range.
◦ reach sparsely populated areas.
◦ penetrate foliage.
◦ add a remote AP behind an SM that operates in another frequency band range.

Issue 2, November 2007 Draft 5 for Regulatory Review 53
5.1.8 Canopy
5.1.9 Backhaul Module
A pair of Backhaul Modules (BHs) provide point-to-point
connectivity as either
◦ a standalone link
◦ a link through a cluster management module to an
AP cluster.
You must configure a BH as either a timing master (BHM)
or timing slave (BHS). The BHM provides synchronization
signal (sync) to the BHS.
A BH mounted to a passive reflector dish is pictured in
Figure 7. Carrier applications for these modules include
reaching remote AP clusters, interconnecting campus
buildings or remote branch offices, extending private
branch exchange (PBX) circuits, backhauling cell sites, and
extending central office T1s/E1s.
These BHs are supported by this user guide. See Realizing
a Wireless Backhaul Network on Page 47.
Figure 7: Dish-mounted
10- or 20-Mbps BH
5.1.10 Radio Adjustable Power Capabilities
Canopy offers adjustable power radios in all frequency bands.See Adjusting Transmitter
Output Power on Page 326 to ensure that your radios do not exceed the maximum
permitted EIRP.
5.1.11 Cluster Management Module-2 (Part 1008CK-2)
The Cluster Management Module-2 (CMM2) provides power, GPS timing from an
antenna that is included, and networking connections for an AP cluster. The CMM2 can
also connect to a BH, in which case the CMM2 is the central point of connectivity for the
entire site. The CMM2 can connect as many as eight collocated modules—APs, BHMs,
BHSs—and an Ethernet feed.
The CMM2 requires two cables for each connected module:
◦ One provides Ethernet communications and power. This cable terminates in an
RJ-45 connector.
◦ The other provides synchronization (sync), GPS status, and time and date in a
serial interface. This cable terminates in an RJ-11 connector.
A CMM2 is pictured in Figure 8. A CMM2 as part of a mounted Canopy system is
pictured in Figure 9.

Figure 9: CMM2 pole-mounted
5.1.12 Cluster Management Module micro (Part 1070CK)
The Cluster Management Module micro (CMMmicro) provides power, GPS timing, and
networking connections for an AP cluster. Unlike the CMM2, the CMMmicro is
configurable through a web interface.
The CMMmicro contains an 8-port managed switch that supports Power over Ethernet
(PoE) on each port and connects any combination of APs, BHMs, BHSs, or Ethernet
feed. Canopy PoE differs from 803.3af PoE, and the two should not be intermixed. The
CMMmicro can auto-negotiate speed to match inputs that are either
100Base-TX or 10Base-T, and either full duplex or half duplex, where the connected
device is set to auto-negotiate. Alternatively, these parameters are settable.
A CMMmicro requires only one cable, terminating in an RJ-45 connector, for each
connected module to distribute
◦ Ethernet signaling.
◦ power to as many as 8 collocated modules—APs, BHMs, or BHSs. Through a
browser interface to the managed switch, ports can be powered or not.
◦ sync to APs and BHMs. The CMMmicro receives 1-pulse per second timing
information from Global Positioning System (GPS) satellites through an antenna
(included) and passes the timing pulse embedded in the 24-V power to the
connected modules.
GPS status information is available at the CMMmicro, however
◦ CMMmicro provides time and date information to BHMs and APs if both the
CMMmicro is operating on CMMmicro Release 2.1 or later and the AP/BHM is
operating on Canopy System Release 4.2 or later.
See Time Tab of the AP on Page 191.
◦ CMMmicro does not provide time and date information to BHMs and APs if either
the CMMmicro is operating on a release earlier than CMMmicro Release 2.1 or
the AP/BHM is operating on a release earlier than Canopy System Release 4.2.

5.1.13 GPS Antenna
The Motorola GPS antenna provides either
◦ timing pulses to the CMMmicro.
◦ timing pulses and positioning information to
the CMM2.
The GPS antenna is pictured in Figure 10.
Figure 10: Motorola GPS antenna
5.1.14 Surge Suppressor (Part 600SS)
The 600SS Surge Suppressor provides a path to
ground (Protective Earth
) that reduces the risk to
persons, buildings, and inside equipment from
over-currents and over-voltages associated with
lightning strikes. A 600SS is pictured in Figure 11.

Passive Reflector Dish Assembly
A 27RD Passive Reflector Dish on both ends of
a BH link extends the distance range of the link
and provides a narrower beam width, which
can reduce both received and transmitted
interference. A 27RD on an SM extends the
distance range in some bands (notably 5.7-
GHz and 2.4-GHz) and can reduce both
received and transmitted interference in all
bands. An SMMThe module support tube
provides the proper offset focus angle. See
Figure 14.
For 5.x-GHz radios, the reflector gain is 18dB
and the 3 dB beam width is 6° in both azimuth
and elevation. For 2.4-GHz radios, the reflector
gain is 11dB and the 3 dB beam width is 17° in
both azimuth and elevation.

Module Support Brackets
The SMMB1 support bracket facilitates
mounting the SM to various surfaces of a
structure and has slots through which chimney
straps can be inserted. An SMMB1 is pictured
in Figure 15.
The SMMB2 is a heavy duty mounting bracket
that comes with the 900-MHz integrated SM or
AP, and with the 27D passive reflector. It is
also available separately for use with 900-MHz
connectorized SMs and APs, other
connectorized modules, and OFDM SMs.
The BH1209 is a pole-mount bracket kit for
Canopy backhaul modules.
Figure 15: SMMB1 SM support bracket
Cables
Canopy modules that are currently or recently sold can auto-sense whether the Ethernet
cable is wired as straight-through or crossover. Some modules that were sold earlier
cannot. The MAC address, visible on the module, distinguishes whether the module can.
All CMMmicros can auto-sense the cable scheme.
Where a non auto-sensing module is deployed
◦ a straight-through cable must be used for connection to a network interface card
(NIC).
◦ a crossover cable must be used for connection to a hub, switch, or router.
Canopy-recommended Ethernet and sync cables can be ordered in lengths up to 328 ft
(100 m) from Best-Tronics Manufacturing, Inc. at
http://www.best-tronics.com/motorola.htm. These cables are listed in Table 8 and

Alignment Headset
The ACATHS-01 Alignment Headset facilitates the
operation of precisely aiming an SM toward an AP (or
a BHS toward a BHM). This device produces infinitely
variable
◦ pitch, higher when the received signal is
stronger.
◦ volume, louder when jitter is less.
An ACATHS-01 is pictured in Figure 16.
Pinouts for an alternative listening device are provided
under Alignment Tone—Technical Details on
Page 184.

Module Housing
The HSG-01 Canopy Plastic Housing is available for
replacement of a damaged housing on a module that is
otherwise functional. The HSG-01 is pictured in
Figure 17.
The HSG-01 and all module housings of this design
provide clearances for cable ties on the Ethernet and sync
cables.
RECOMMENDATION:
Use 0.14” (40-lb tensile strength) cable ties
to secure the Ethernet and sync cables to
the cable guides on the module housing.
For the Ethernet cable tie, the Ethernet cable groove is
molded lower at the top edge. For the sync cable tie,
removal of a breakaway plug provides clearance for the
sync cable, and removal of two breakaway side plates
provides clearance for the sync cable tie.

5.2 FREQUENCY BAND RANGES
In the 2.4-, 5.2-, 5.1-, 5.4-, and 5.7-GHz frequency band ranges, Canopy APs, SMs, and
BHs are available. Additionally, in the 900-MHz frequency band range, Canopy APs and
SMs are available. National restrictions may apply. See Regulatory and Legal Notices on
Page 487.
To avoid self-interference, a Canopy network typically uses two or more of these ranges.
For example, where properly arranged, all AP clusters and their respective SMs can use
the 2.4-GHz range where the BH links use the 5.7-GHz range. In this scenario,
subscriber links can span as far as 5 miles (8 km) with no reflector dishes, and the BH
links can span as far as 35 miles (56 km) with reflector dishes on both ends.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 60
Within this example network, wherever the 2.4-GHz module is susceptible to interference
from other sources, AP clusters and their linked SMs may use the 5.2-GHz range to span
as far as 2 miles (3.2 km) with no reflector dishes. The network in this example takes
advantage of frequency band range-specific characteristics of Canopy modules as
follows:
◦ The 900-MHz modules cover a larger area, albeit with lower throughput, than
modules of the other frequency bands. The 900-MHz modules can be used to
− penetrate foliage
− establish links that span greater distances
− add subscribers
− add overall throughput where modules of other frequency bands cannot be
used (such as where interference would result or space on a tower is
limited).
◦ The 2.4-GHz frequency band range supports AP/SM links of greater than 2-mile
spans (with no reflectors).
◦ The 5.7-GHz frequency band range supports BH links that span as far as 35
miles.

NOTES:
1. National or regional regulations may limit EIRP to the same as without a reflector, and therefore
require Transmit Output Power to be reduced. In these cases
◦ the reflector used with an SM reduces beamwidth to reduce interference, but does not increase
the range of the link.
◦ the reflector on both ends of a BH link reduces beamwidth to reduce interference and also
increases the range of the link.

NOTES:
2. In Europe, 2.4-GHz ETSI and 5.4-GHz SMs can have a reflector added to focus the antenna pattern and reduce
interference, but transmit output power must be reduced to maintain the same EIRP as without a reflector, so
the throughput and range specs for PTMP links remain the same.
3. In the USA and Canada, the use of a reflector with a full power radio in the 5.2-GHz frequency band is not
allowed.
4. These values assume a hardware series P9 AP running hardware scheduler. When running software scheduler
on a series P7, P8, or P9 AP, aggregate throughput drops to 6.2 Mbps, and only 4 Mbps is available to any one
SM. (Series P7 and P8 APs can only run software scheduler.)
5. All 900-MHz APs are Advantage APs.
GENERAL NOTES:
Range is affected by RF conditions, terrain, obstacles, buildings, and vegetation.
An Advantage AP in other than 900 MHz has an aggregate (sum of uplink plus downlink) throughput or capacity of
14 Mbps, if RF conditions, range, and SM hardware version permit.
An Advantage SM in other than 900 MHz has an aggregate sustained throughput of 14 Mbps if RF conditions and
range permit.
A regular SM can burst to 14 Mbps if RF conditions and range permit, then run at 7 Mbps sustained throughput.
An OFDM SM has an aggregate throughput or capacity of XX Mbps, if RF conditions and range permit.d

5.4 ANTENNAS FOR CONNECTION TO 900-MHz MODULES
Like the 2.4-, 5.2-, 5.4-, and 5.7-GHz module, the 900-MHz connectorized module has
◦ the same housing.
◦ a covered Ethernet port.
◦ a utility port for alignment headset, sync cable to CMM2, or override plug.
The 900-MHz AP or SM is available either
◦ as a connectorized unit with a 16-inch (approximately 40-cm) cable with a male
N-type connector for connection to the antenna.
◦ with an integrated horizontally-polarized antenna in a different form factor.
5.4.1 Certified Connectorized Flat Panel Antennas
Motorola has certified four connectorized flat panel antenna options. Motorola resells one
of these, whose attributes include
◦ gain—10 dBi
◦ dimensions—8.8 x 8.1 x 1.6 inches (22.4 x 20.6 x 4.06 cm)
◦ weight—1.2 lbs (0.54 kg)
◦ polarization—vertical or horizontal
◦ cable—12-inch (30.5 cm)
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 65
◦ connector—female N-type
◦ beamwidth—approximately 60° vertical and 60° horizontal at 3 dBm
Motorola has certified three other antennas, which are available through Canopy
resellers. The attributes of one of these other certified antennas include
◦ gain—10 dBi
◦ dimensions—12 x12 x 1 inches (30.5 x 30.5 x 2.5 cm)
◦ weight—3.3 lbs (1.5 kg)
◦ polarization—vertical or horizontal
◦ connector—female N-type
◦ beamwidth—approximately 60° vertical and 60° horizontal at 3 dBm
Examples of these antennas are pictured in Figure 6 on Page 52.

5.6 BANDWIDTH AND AUTHENTICATION MANAGER
Canopy Bandwidth and Authentication Manager (BAM) software allows you to use
◦ a primary server to distribute bandwidth resources per subscriber, require SMs to
authenticate per AP, and deny service to unauthorized SMs.
◦ a secondary server to redundantly store identical SM bandwidth and
authentication data and become governing if the primary server goes out of
service.
◦ an optional tertiary server to do the same if both the primary and secondary
servers go out of service.
In BAM Release 2.1, subscriber administration for an SM or batch of SMs is performed
as follows:
◦ Insert the ESNs.
◦ Specify MIR and Security attributes.
◦ Specify CIR attributes.
◦ Specify whether BAM should send its stored CIR attributes.
◦ Specify VLAN attributes.
◦ Specify whether BAM should send its stored VLAN attributes.
◦ Specify VLAN IDs to associate with the SM(s).
This product is supported by the dedicated document Canopy Bandwidth and
Authentication Manager Release 2.1 User Guide and associated release notes.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 67
The upgrade path from BAM Release 2.1 is Prizm Release 2.0. See Motorola Canopy
Prizm User Guide, Issue 3, and Motorola Canopy Prizm Release 2.0 Release Notes.
5.7 Prizm
The product name PrizmEMS is changed to Prizm in Release 2.0 and later, to reflect that
the product capabilities are expanded beyond those of the element management system
(EMS). Throughout this user guide, the name change applies to text for Release 2.0 and
for multiple releases that include 2.0. It does not apply to text that is for a previous
release. Case by case, software elements such as the GUI in the client application and
XML files on the server may retain the PrizmEMS syntax.
5.7.1 Network Definition and Element Discovery
Prizm allows the user to partition the entire Canopy network into criteria-based subsets
that can be independently managed. To assist in this task of defining networks, Prizm
auto discovers Canopy network elements that are in
◦ user-defined IP address ranges
◦ SM-to-AP relationships with APs in the user-defined range
◦ BHS-to-BHM relationships with BHMs in the user-defined range.
◦ PLV Modem-to-PLV Bridge relationships with PLV Bridges in the user-defined
range.
For a Canopy AP, SM, BHM, BHS, PLV Bridge, PLV Modem, or CMMmicro, Prizm
◦ auto discovers the element to the extent possible.
◦ includes the element in the network tree.
◦ shows general information.
◦ shows Canopy information.
◦ supports Canopy-specific operations.
For a generic element, Prizm
◦ auto discovers the element as only a generic network element.
◦ includes the element in the network tree.
◦ shows general information.
◦ shows events and alerts.
◦ charts port activity.
For passive elements (such as CMM2 or a non-manageable switch or hub), Prizm allows
you to enter into the network tree a folder/group with name, asset/owner information, and
descriptive information.

5.7.2 Monitoring and Fault Management
Prizm receives the traps that Canopy elements send and generates an alert for each of
these. Prizm also allows the user to establish sets of criteria that would generate other
alerts and trigger email notifications. Optionally, the user can specify a trap template. In
this case, Prizm receives traps for non-Canopy elements in the network.
For any individual element that the user selects, Prizm offers text and graphed displays of
element configuration parameters and performance statistics from an interval that the
user specifies.
5.7.3 Element Management
Prizm allows the user to perform any of the following operations on any specified element
or group of elements:
◦ Manage
− large amounts of SNMP MIB data.
− module passwords.
− IP addresses.
− other communications setup parameters.
− site information: Site Name, Site Location, and Site Contact parameters.
◦ Reset the element.
5.7.4 BAM Subsystem in Prizm
Prizm Release 2.0 and later integrates Canopy Bandwidth and Authentication Manager
(BAM) functionality and supports simple migration of a pre-existing BAM data into the
Prizm database. These releases also support the maintenance of authentication and
bandwidth data on a RADIUS server, to the same extent that BAM Release 2.1 (the final
release of BAM) did.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 69
Either of the following modes is available for the Prizm server, subject to licensing:
◦ BAM-only functionality, which manages only
− authentication, bandwidth service plans, and VLAN profiles of SMs.
− authentication of Powerline LV modems.
◦ Full Prizm functionality, which manages attributes for all elements and
authentication of SMs and Powerline LV modems.
One difference between a service plan (or VLAN profile) and a configuration template
that has the identical set of attributes is that the former is a long-term association
whereas the latter is a one-time push to the element. When a service plan or VLAN
profile is modified, the change is automatically applied to all elements that have the
association. Another difference is that a configuration template cannot overwrite any
values that a service plan or VLAN profile has set in an element.
5.7.5 Northbound Interface
In Release 1.1 and later, Prizm provides three interfaces to higher-level systems:
◦ a Simple Network Management Protocol (SNMP) agent for integration with a
network management system (NMS).
◦ a Simple Object Access Protocol (SOAP) XML-based application programming
interface (API) for web services that supports integration with an operations
support systems (OSS) such as a customer relationship management (CRM),
billing, or provisioning system.
◦ console automation that allows such higher-level systems to launch and
appropriately display the Prizm management console in GUI that is custom
developed, using the PrizmEMS™ Software Development Kit (SDK), which
Canopy provides for this purpose.
Together these interfaces constitute the Northbound Interface feature. Prizm server
administrator tasks and GUI developer information are provided in the PrizmEMS™
Software Development Kit (SDK). This SDK also describes the how to define new
element types and customize the Details views.
All other features of the Prizm product are supported by the dedicated document
Motorola Canopy Prizm User Guide and associated release notes.
5.8 LICENSE MANAGEMENT
Under the original licensing regime for Canopy networks, licenses were permanently tied
to the Media Access Control (MAC) address of the equipment that was licensed or that
used the licensed feature. Thus, they were not transferable. Under server-based license
management, for some functionalities, Canopy offers licenses that
◦ float upon demand within the network.
◦ are tied to only the osted (MAC address) of the license management server for
which they were ordered.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 70
In Release 4.2.3 and later, server-based license management adds flexibility and makes
available licenses that previously would have been held by de-commissioned equipment.
License management technology from Macrovision, based on a FLEXnet™ Publisher
license management model, provides the platform for Canopy server-based licensing.
Canopy capabilities that are authorized by licenses on this platform are FLEXenabled
products.
In this platform, the license management server checks and then either assigns or
declines to assign a license in real time. See the Canopy Networks License Manager
User Guide.
The total number of floating license keys that you need for any feature is the highest
number that you will ever want to have simultaneously in use. The proper placement of
these keys and the number and placement of fixed Canopy licenses are listed in
Table 17.

6 DIFFERENTIATING AMONG COMPONENTS
6.1 INTERPRETING MODEL (PART) NUMBER
The part number of a module typically represents
◦ the model number, which may indicate
− radio frequency band range.
− link distance range.
− whether the module is Canopy Advantage.
− the factory-set encryption standard.
◦ the module type.
◦ whether the reflector dish is included.
◦ the antenna scheme of the module.
◦ whether adjustable power in the module is preset to low.
◦ the modulation capability.
Radio Frequency Band Range
The leading digits usually indicate the frequency band range in which the module can
operate. For example, if the part number is 5700BH, then the frequency band range of
the module is 5.7 GHz.
↓

7
0

B
H
An exception to this general rule is that the leading digits in the part number of 5.1-GHz
modules are 52. These modules are differentiated from 5.2-GHz modules by the leading
four digits (5202 for 5.1 GHz, 5200 for 5.2 GHz).
You cannot change the frequency band range of the module.
Link Distance Range or Canopy Advantage
The third digit in the part number may indicate whether the module is an extended range,
Canopy Advantage, or Canopy model. 1 indicates extended range. For example, if the
part number is 5210BH, then the module is an extended range module. If the part
number is 5200BH, then the module is not an extended range model.

6 in the third position (5760SM, for example) indicates Canopy Lite. 5 in the third position
(5250AP, for example) indicates that the module is Canopy Advantage. 0 in the third
position (5200AP, for example) indicates that the module is Canopy. However, part
numbering for 900-MHz APs and SMs differs from this general rule. All APs and SMs in
this frequency band range are Canopy Advantage, but none of their part numbers use 5
in the third position.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 76
You cannot change the link distance range of the module. However, you can license a
Canopy SM to uncap its aggregate throughput (a capability of the Advantage SM).
Encryption Standard or Frequency Band Range
The fourth digit in the part number usually indicates the encryption standard that was
preset at the factory. 1 indicates the Advanced Encryption Standard (AES). 0 indicates
the Data Encryption Standard (DES) standard. For example, if the part number is
5201BH, then transmissions from the module are encrypted according to AES. If the part
number is 5200BH, then transmissions from the module are encrypted according to DES.

An exception to this general rule is that the fourth digit in the part number of 5.1-GHz
modules is 2. These modules are differentiated from 5.2-GHz modules by the leading
four digits (5202 for 5.1 GHz, 5200 for 5.2 GHz).
You cannot change the encryption basis (from DES to AES, for example), but you can
enable or disable the encryption.
Module Type
The next two alpha characters indicate the module type. For example, CK indicates that
the module is a Cluster Management Module.

The module type cannot be changed.
Reflector Added
In specifications tables and price lists, the trailing characters RF or RF20 indicate that the
associated information applies to the module being
◦ mounted to the 27RD Passive Reflector Dish, in the case of specifications.
◦ ordered with the 27RD Passive Reflector Dish, in the case of price lists.

An F in this position indicates that the module has an internal antenna with a band-pass
filter (for example, 9000APF).
You cannot transform a module from connectorized to internal antenna or from internal
antenna to connectorized, but you may have flexibility in what external antenna you
deploy with it.
Adjustable Power Preset to High or Low
A trailing WL can indicate that the module had adjustable power that is preset to low.

However, the 5700SMC and 5700APC are connectorized, but also have adjustable
power preset to low. No special designation is made for adjustable power that is set to
high (no trailing letters are used; for example, 5252AP).
You can reset power to higher in a module with adjustable power that is preset to low, but
you are constrained by applicable regulations in your region and or nation.
Modulation Capability
A trailing 20 indicates that the module is capable of being set to either
◦ 20-Mbps modulation (aggregate throughput of 14 Mbps)
◦ 10-Mbps modulation (aggregate throughput of 7 Mbps).

6.3 INTERPRETING ELECTRONIC SERIAL NUMBER (ESN)
Canopy module labels contain a product serial number that could be significant in your
dealings with Motorola or your supply chain. This is the electronic serial number (ESN),
also known as the Media Access Control (MAC) address, of the module. This
hexadecimal number identifies the module in
◦ communications between modules.
◦ the data that modules store about each other (for example, in the Registered To
field).
◦ the data that the BAM software applies to manage authentication and bandwidth.
◦ Prizm auto discovery of SMs through the AP (or BHS through the BHM).
◦ software upgrades performed by the Canopy Network Updater Tool (CNUT).
◦ information that CNUT passes to external tools.
6.4 FINDING THE MODEL (PART) NUMBER AND ESN
The labels and locations of Canopy module model (part) numbers and ESNs are shown

7 CANOPY LINK CHARACTERISTICS
7.1 UNDERSTANDING BANDWIDTH MANAGEMENT
7.1.1 Downlink Frame Contents
The AP broadcasts downlink frames that contain control information, allocating slots in
succeeding or future uplink frames to SMs that have requested service. The downlink
frame also contains a beacon frame, control information, and data that specific SMs have
requested. Each SM
◦ examines the downlink frame to distinguish whether data is addressed to
that SM.
◦ retrieves data addressed to that SM.
◦ directs such data to the appropriate end user.
7.1.2 Uplink Frame Contents
Uplink frames contain control information from each SM that request service on
succeeding uplink frames. SMs insert data into the uplink frames in an amount that the
AP has established.
Optionally, you can configure the AP to change the source MAC address in every packet
it receives from its SMs to the MAC address of the SM that bridged the packet, before
forwarding the packet toward the public network. If you do, then
◦ not more than 10 IP devices at any time are valid to send data to the AP from
behind the SM.
◦ the AP populates the Translation Table tab of its Statistics web page, displaying
the MAC address and IP address of all the valid connected devices.
◦ each entry in the Translation Table is associated with the number of minutes that
have elapsed since the last packet transfer between the connected device and
the SM.
◦ if 10 are connected, and another attempts to connect
− and no Translation Table entry is older than 255 minutes, the attempt is
ignored.
− and an entry is older than 255 minutes, the oldest entry is removed and the
attempt is successful.
◦ the Send Untranslated ARP parameter in the General tab of the Configuration
page can be
− disabled, so that the AP will overwrite the MAC address in Address
Resolution Protocol (ARP) packets before forwarding them.
− enabled, so that the AP will forward ARP packets regardless of whether it
has overwritten the MAC address.
This is the Translation Bridging feature, which you can enable in the General tab of the
Configuration web page in the AP. When this feature is disabled, the setting of the Send
Untranslated ARP parameter has no effect, because all packets are forwarded
untranslated (with the source MAC address intact).
See Address Resolution Protocol on Page 162.

March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 82
7.1.3 Default Frame Structures
With a 64-byte slot size, the default Canopy frame in hardware scheduling consists of
◦ variable numbers of uplink and downlink data slots, subject to the following
factors:
− Maximum range decreases the number of available slots to 32.
− Background bit error rate (BER) mode decreases the number of available
data slots by one (and bandwidth by 200 kbps).
− Every two control slots that are allocated decrease the number of available
data slots by one.
◦ 0 to 10 control slots, subject to operator setting
◦ 0 to 9 downlink acknowledgement slots, dynamically assigned
◦ 0 to 9 uplink acknowledgement slots, dynamically assigned
◦ 1 uplink schedule slot
◦ 1 beacon slot, which identifies the
− timing and distribution for the SMs
− ratio of uplink to downlink allocation
− ESN of the AP
− color code
− protocol (point-to-point or point-to-multipoint)
− number of registered SMs
− frame number
− control slot information
◦ air delay, subject to the value of the Max Range parameter in the AP
Control Slots
The Radio tab of the Configuration web page in the AP displays the total of control slots
(default 3, maximum 7 in the 900-MHz frequency band range2 and 16 in all others).
These control slots are contention slots. If too many SMs contend for these slots, then
the number of control slots may be increased.
Frame Scheduling
When an SM boots, the following sequence occurs:
1. The SM finds this beacon slot from an AP.
2. The SM synchronizes with the AP.
3. If BAM is configured on the AP and the AP is licensed for authentication, then
a. the AP sends a Registration Request message to Prizm for authentication.
b. following a successful challenge, Prizm returns an Authentication Grant
message to the AP.
c. the AP sends a Registration Grant to the SM.
2 In the 900-MHz frequency band range, the frame size is 16,667 bits. In all others, the frame size
is 25,000 bits. The smaller frame does not provide enough space to allocate more than 7 control
slots.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 83
If BAM is not configured on the AP or the AP is not licensed for authentication,
then the AP simply returns the Registration Grant to the SM.
This Registration Grant includes the distance between the AP and SM. The SM uses the
distance to distinguish when to transmit data in the uplink frame. The AP performs
advance scheduling of up to 1024 frames that each SM will be permitted to use in the
uplink frame.
7.1.4 Media Access Control and AP Capacity
Regardless of whether the maximum number of SMs (200) all request service at the
same time, the reservation Media Access Control (MAC) system allows the AP to give a
reservation slot to each SM that requests service.
Regardless of the distance between any SM and the AP, the reservation MAC system
ensures that all SM data slots are free of contention. For this reason
◦ all SMs are equally able to compete for uplink and downlink bandwidth.
◦ the capacity of the AP is not degraded by distance from the SMs.
7.1.5 Canopy Slot Usage
The frame illustrated in Figure 18 shows both packet fragments (yellow) and unused slot
space (red) typical of uplink traffic. Packet sizes smaller than 64 bytes cause unused slot
spaces.
Figure 18: Uplink data slot usage
The following statistics apply to Canopy frame slot usage:
◦ Slot capacity is 64 bytes.
◦ The optimum Ethernet packet size is 1518 bytes.
◦ The maximum downlink throughput for one AP to one SM is 1800 packets per
second (pps).
◦ The maximum uplink throughput for one AP to one SM is 300 pps.
◦ The maximum backhaul throughput is 3000 pps.
7.1.6 Data Transfer Capacity
Canopy modules use Time Division Duplex (TDD) on a common frequency to divide
frames for uplink (orange) and downlink (green) usage, as shown in Figure 19.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 84
Figure 19: TDD dividing Canopy frames
7.1.7 Maximum Information Rate (MIR) Parameters
Canopy point-to-multipoint links use the following four MIR parameters for bandwidth
management:
◦ Sustained Uplink Data Rate (kbps)
◦ Uplink Burst Allocation (kb)
◦ Sustained Downlink Data Rate (kbps)
◦ Downlink Burst Allocation (kb)
You can independently set each of these parameters per AP or per SM.
Token Bucket Algorithm
The Canopy software uses a token bucket algorithm that
◦ stores credits (tokens) for the SM to spend on bandwidth for reception or
transmission.
◦ drains tokens during reception or transmission.
◦ refills with tokens at the sustained rate set by the network operator.
For each token, the SM can send toward the network in the uplink (or the AP can send
toward the SM in the downlink) an equivalent number of kilobits. Two buckets determine
the permitted throughput: one in the SM for uplink and one in the AP for downlink.
The applicable set of Uplink Burst Allocation and Downlink Burst Allocation
parameters determine the number of tokens that can fill each bucket. When the SM
transmits (or the AP transmits) a packet, the equivalent number of tokens is removed
from the uplink (or downlink) bucket.
Except when full, the bucket is continuously being refilled with tokens at rates that the
applicable set of Sustained Uplink Data Rate and Sustained Downlink Data Rate
parameters specify. The bucket often drains at a rate that is much faster than the
sustained data rate but can refill at only the sustained data rate. Thus, the effects of the
allocation and rate parameters on packet delay are as follows:
◦ the burst allocation affects how many kilobits are processed before packet delay
is imposed.
◦ the sustained data rate affects the packet delay that is imposed.
Which set of these MIR parameters are applicable depends on the interactions of other
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 85
parameter values. These interactions are described under Setting the Configuration
Source on Page 292. Also, where the Configuration Source parameter setting in the AP
specifies that BAM values should be used, they are used only if Prizm is configured to
send the values that it stores for the MIR parameters.
MIR Data Entry Checking
Uplink and downlink MIR is enforced as shown in Figure 20.
NOTE:
In these figures, entry refers to the setting in the data rate parameter, not the
burst allocation parameter.
uplink cap enforced =
uplink entry x aggregate cap for the SM
uplink entry + downlink entry
downlink cap enforced =
downlink entry x aggregate cap for the SM
uplink entry + downlink entry
Figure 20: Uplink and downlink rate caps adjusted to apply aggregate cap
For example, in the Canopy SM, if you set the Sustained Uplink Data Rate parameter to
2,000 kbps and the Sustained Downlink Data Rate parameter to 10,000 kbps, then the
uplink and downlink MIR that will be enforced for the SM can be calculated as shown in
Figure 21.
uplink cap enforced =
2,000 kbps x 7,000 kbps
2,000 kbps + 10,000 kbps
= 1,167 kbps
downlink cap enforced =
10,000 kbps x 7,000 kbps
2,000 kbps + 10,000 kbps
= 5,833 kbps
Figure 21: Uplink and downlink rate cap adjustment example
In this example case, the derived 1,167-kbps uplink and 5,833-kbps downlink MIR sum to
the fixed 7,000-kbps aggregate cap of the Canopy SM.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 86
7.1.8 Committed Information Rate
The Committed Information Rate (CIR) capability feature enables the service provider to
guarantee to any subscriber that bandwidth will never decrease to below a specified
minimum, unless CIR is oversubscribed. Bandwidth can be, and typically will be, higher
than the minimum, but this guarantee helps the WISP to attract and retain subscribers.
In BAM Release 2.1 and in Prizm Release 2.0, CIR configuration is supported as follows:
◦ The GUI allows you to view and change CIR configuration parameters per SM.
◦ When an SM successfully registers and authenticates, if BAM or Prizm has CIR
configuration data for the SM, then messages make the CIR configuration
available to the SM, depending on the Configuration Source setting. (See Setting
the Configuration Source on Page 292.)
◦ The operator can disable the CIR feature in the SM without deleting the CIR
configuration data.
7.1.9 Bandwidth from the SM Perspective
In the Canopy SM, normal web browsing, e-mail, small file transfers, and short streaming
video are rarely rate limited with practical bandwidth management (QoS) settings. When
the SM processes large downloads such as software upgrades and long streaming video
or a series of medium-size downloads, the bucket rapidly drains, the burst limit is
reached, and some packets are delayed. The subscriber experience is more affected in
cases where the traffic is more latency sensitive.
Example download times for various arbitrary tiers of service are shown in Table 56 on
Page 382 and Table 57 on Page 383.
7.1.10 Interaction of Burst Allocation and Sustained Data Rate Settings
If the Burst Allocation is set to 1200 kb and the Sustained Data Rate is set to 128 kbps, a
data burst of 1000 kb is transmitted at full speed because the Burst Allocation is set high
enough. After the burst, the bucket experiences a significant refill at the Sustained Data
Rate. This configuration uses the advantage of the settable Burst Allocation.
If both the Burst Allocation and the Sustained Data Rate are set to 128 kb, a burst is
limited to the Burst Allocation value. This configuration does not take advantage of the
settable Burst Allocation.
If the Burst Allocation is set to 128 kb and the Sustained Data Rate is set to 256 kbps, the
actual rate will be the burst allocation (but in kbps). As above, this configuration does not
take advantage of the settable Burst Allocation.
7.1.11 High-priority Bandwidth
To support low-latency traffic such as VoIP (Voice over IP) or video, the Canopy system
implements a high-priority channel. This channel does not affect the inherent latencies in
the Canopy system but allows high-priority traffic to be immediately served. The high-
priority pipe separates low-latency traffic from traffic that is latency tolerant, such as
standard web traffic and file downloads.
A Canopy module prioritizes traffic by
◦ reading the Low Latency bit (Bit 3) in the IPv4 Type of Service (ToS) byte in a
received packet.
◦ reading the 802.1p field of the 802.1Q header in a received packet, where VLAN
is enabled on the module.

◦ comparing the 6-bit Differentiated Services Code Point (DSCP) field in the ToS
byte of a received packet to a corresponding value in the DiffServe tab of the
Configuration page of the module.
Low Latency Bit
Bit 3 is set by a device outside the Canopy system. In the uplink frame, the SM monitors
Bit 3. If this bit is set, then
◦ the SM prioritizes this traffic in its high-priority queue according to AP
configuration settings for the high-priority channel.
◦ the system sends the packet on the high-priority channel and services this
channel before any normal traffic.
802.1P Field
See Priority on VLANs (802.1p) on Page 166.
DSCP Field
Like Bit 3 of the original IPv4 ToS byte, the DSCP field (Bits 0 through 5) in the redefined
ToS byte is set by a device outside the Canopy system. A packets contains no flag that
indicates whether the encoding is for the Low Latency bit or the DSCP field. For this
reason, you must ensure that all elements in your trusted domain, including routers and
endpoints, set and read the ToS byte with the same scheme.
Canopy modules monitor ToS bytes with DSCP fields, but with the following differences:
◦ The 6-bit length of the field allows it to specify one of 64 service differentiations.
◦ These correlate to 64 individual (CodePoint) parameters in the DiffServe tab of
the Configuration page.
◦ Per RFC 2474, 3 of these 64 are preset and cannot be changed. (See
http://www.faqs.org/rfcs/rfc1902.html.)
◦ For any or all of the remaining 61 CodePoint parameters, you can specify a value
of
− 0 through 3 for low-priority handling.
− 4 through 7 for high-priority handling.
RECOMMENDATION:
Ensure that your Differentiated Services domain boundary nodes mark any
entering packet, as needed, so that it specifies the appropriate Code Point for
that traffic and domain. This prevents theft of service level.
An example of the DiffServe tab in the Configuration page and parameter descriptions
are provided under DiffServe Tab of the AP on Page 256. This tab and its rules are
identical from module type to module type in Canopy. However, any of the 61
configurable Code Points can be set to a different value from module to module, thus
defining unique per-hop behavior for some traffic.
This tab in the AP and BHM sets the priorities for the various packets in the downstream
(sent from the public network). This tab in the SM and BHS sets the priorities for the
various packets in the upstream (sent to the public network).
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 88
Typically in the Canopy network, some SMs attach to older devices that use the ToS byte
as originally formatted, and others to newer devices that use the DSCP field. The default
values in the DiffServe tab allow your modules to prioritize traffic from the older devices
roughly the same as they traditionally have. However, these default values may result in
more high-priority traffic as DSCP fields from the newer devices are read and handled.
So, after making any changes in the DiffServe tab, carefully monitor the high-priority
channel for high packet rates
◦ in SMs that you have identified as those to initially set and watch.
◦ across your Canopy network when you have broadly implemented Code Point
values, such as via SNMP.

7.1.12 Hardware Scheduling
Canopy Release 8 supports only hardware scheduling. Hardware scheduling always
sends high-priority traffic first, even to the exclusion of other traffic.
IMPORTANT!
The number of channels available to the AP is reduced by the number of SMs
configured for the high-priority channel. With this feature enabled on all SMs, an
AP can support 100 SMs (instead of 200).
Canopy Release 8 requires APs, BHs, and AES SMs to be Series P9 or later hardware.3
The characteristics of hardware scheduling in a Canopy sector are summarized in
Table 22.

Power requirements for modules that run hardware scheduling affect the
recommended maximums for power cord length feeding the CMMmicro. See
Table 51 on Page 342. However, the requirements do not affect the maximums
for the CMM2.
Packets that have a priority of 4 to 7 in either the DSCP or a VLAN 802.1p tag are
automatically sent on the high-priority channel, but only where the high-priority channel is
enabled.
7.1.13 2X Operation
A General tab option in both Advantage SMs and hardware series P9 and greater
Canopy SMs provides double the aggregate throughput for SMs that are nearer than half
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 90
of the maximum typical range from the AP. The requirements of this feature are as
follows:
◦ The AP must be an Advantage AP.
◦ The SM must be near the AP, roughly half the range of 1X.
◦ The SM must be of the P9 hardware series or later and enabled for hardware
scheduling. See Designations for Hardware on Page 365.
◦ The 2X Rate parameter in the SM must be set to enabled. This is the default
setting.
◦ The amount of noise and multipath must be low enough to allow the receiver in
the 6 dB less sensitive (2X) state to maintain a high carrier-to-interference (C/I)
ratio.
The flexibility of this feature is as follows:
◦ At the time of registration, signaling is at the 1X rate. However, if the above
requirements are all met, then the SM switches to 2X.
◦ Thereafter, whenever RF conditions are unfavorable for 2X operation, the SM
switches to 1X. When favorable RF conditions allow, the SM switches back to
2X, if user data is present at that time.
◦ Similarly, whenever no user data is present, the SM switches to 1X. When user
data flow resumes, the SM switches back to 2X, if RF conditions allow.
◦ Both links for the SM (uplink and downlink) are independent for this feature.
(One can be operating at 2X operation while the other is operating at 1X.)
◦ Other SMs in the sector can be communicating with the AP at the other
modulation rate.
◦ Although subscribers with Canopy SMs realize higher bursts, and subscribers
with Advantage SMs realize both higher burst and higher sustained throughput,
the network operator realizes higher sector throughput capacity in the AP.
The effect of 2X operation on aggregate throughput for the SM is indicated in Table 23.

Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 91
Competition for Bandwidth
When multiple SMs vie for bandwidth, the AP divides its bandwidth among them,
considering their effective CIR and MIR values. However, 2X operation uses bandwidth
twice as efficiently as 1X, even where MIR values apply. This is because, in 2X
operation, the modules transmit their data in 4-level frequency shift keying (FSK), not
2-level as they would in 1X operation. This moves twice the data per slot. Thus, for the
sum of all bandwidth that 2X-eligible customers use, the bandwidth available to the
remaining customers increases by half of that sum when these eligible customers are
transmitting and receiving in 2X operation.
Engineering for 2X Operation
The following priorities should guide your implementation of 2X operation:
◦ In the near half of the distance range of the AP
− identify the customers who use the most bandwidth.
− enable their SMs first for 2X operation.
◦ When you have deployable Canopy P7 and P8 SMs, do not deploy Canopy
Advantage SMs or Canopy P9 SMs beyond half the distance range of the AP.
At this distance, steady and reliable 2X operation typically is not achievable.
Deploy the Canopy P7 and P8 SMs here.
◦ Wherever practical, implement 25 MHz of channel separation for 2X operation.
Checking Link Efficiencies in 2X Operation
Unlike in 1X operation, efficiencies below 90% on the Link Capacity Test tab in the Tools
web page of the SM may be acceptable for stable operation. An efficiency of 60% in 2X
operation is equivalent to an efficiency of 120% in 1X. If you read efficiency between 60%
and 90%, check the status of 2X operation (as described below) to confirm that the link is
operating at 2X.
Since received signal strength typically varies over time, you should perform link tests at
various times of day and on various days of the week. Efficiencies should consistently be
60% or greater for 2X operation. You may be able to achieve better efficiencies by re-
aiming the SM, mounting it elsewhere, or adding a reflector dish.
Checking the Status of 2X Operation
The Session Status tab in the Home page of the AP provides operation status information
about each SM-to-AP link. Under the MAC address of each SM, the data in this tab
includes a line such as the following:
RATE : VC 19 Rate 2X/2X VC 255 Rate 2X/1X
Interpret this information is as follows:
◦ VC means virtual channel. If one VC is displayed, the high-priority channel is
disabled. If two are displayed, the high-priority channel is enabled and is using
the higher number VC (255 in the above example).
◦ 2X/2X indicates that the SM-to-AP link is in 2X operation.
◦ 2X/1X indicates that the SM is capable of 2X operation but the SM-to-AP link is in
1X operation. This can be for either of the following reasons:
− The SM has not sent data on the channel yet.
− The received signal does not support 2X operation.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 92
◦ 1X/1X indicates that the SM is capable of only 1X operation. This can be for
either of the following reasons:
− The SM does not support 2X operation (SM is of the hardware series P7
or P8).
− The 2X Rate parameter is disabled in the General tab of the Configuration
page in the SM or the AP.
CAUTION!
2X operation requires approximately 3 to 5% more power than 1X operation.
This additional power affects the recommended maximum for power cord length
feeding the CMMmicro. See Table 51 on Page 342. However, 2X operation
does not affect the maximums for the CMM2.
Disabling 2X Operation
Disabling 2X operation for an SM can be helpful for alignment, troubleshooting, or
preventing frequent automatic switches between 2X and 1X, where RF conditions are
only marginally favorable to 2X. The ability to disable 2X for an SM is inherent since the
2X Operation feature was introduced.
Disabling 2X operation for a sector can be helpful for identifying a baseline for 1X-to-2X
comparison, broader troubleshooting activities, or forcing all SMs to 1X rather than
disabling 2X in each SM. Release 8 provides a 2X Rate parameter in the General tab of
the Configuration page in the AP:
◦ If you click Disable, then Save Changes and Reboot, 2X operation is disabled
for the sector, regardless of the 2X Rate setting in each SM.
◦ If you later click Enable, then Save Changes and Reboot, 2X operation is
enabled in the sector for SMs with 2X Rate enabled on their
Configuration>General page. SMs with 2X Rate disabled on their
Configuration>General page (or P7 or P8 SMs that don’t support 2X Rate) will
only operate at 1X.
7.1.14 3X Operation (Canopy OFDM modules only)
Canopy OFDM modules offer an additional modulation scheme that provides 3X
operation in addition to 1X and 2X operation. In clear space, 3X operation is possible
over half the range of 2X (which means it is possible over ¼ the range of 1X). However,
in NLOS installations (typical for Canopy OFDM), multipathing may be the predominant
RF issue, not free-space attenuation, so the relationship between 1X, 2X, and 3X range
may differ from clear space situations.
3X operation is configured on a Canopy OFDM module’s Configuration => General page
using the Dynamic Rate Adapt pop-up under Mac Control Parameters.
7.2 UNDERSTANDING SYNCHRONIZATION
The system usesTime Division Duplexing (TDD) - one channel alternately transmits and
receives - rather than using one channel for transmitting and a second channel for
receiving. To accomplish TDD, the AP must provide sync to its SMs – it must keep them
in sync. Furthermore, collocated APs must be synced together - an unsynchronized AP
that transmits during the receive cycle of a collocated AP can prevent that second AP
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 93
from being able to decode the signals from its SMs. In addition, across a geographical
area, APs that can “hear” each other benefit from using a common sync to further reduce
self-interference within the network.
7.2.1 GPS Synchronization
The Navigation Satellite Timing and Ranging (NAVSTAR) Global Positioning System
(GPS) uses 24 satellites to relay information for precise derivation of position and time.
The Canopy Cluster Management Module (CMM) contains a Motorola Oncore GPS
Receiver. The CMM is a critical element in the operation of the Canopy system. At one
AP cluster site or throughout an entire wireless system, the CMM provides a GPS timing
pulse to each module, synchronizing the network transmission cycles.
The Oncore GPS Receiver tracks eight or more satellites. The CMM uses the signal from
at least four of these satellites to generate a one-second interval clock that has a rise
time of 100 nsec. This clock directly synchronizes APs and BHMs which, in turn,
synchronize the SMs and BHSs in the Canopy network.
The Oncore GPS Receiver also provides
◦ the latitude and longitude of the GPS antenna (collocated with the CMM)
◦ the number of satellites that are being tracked
◦ the number of satellites that are available
◦ the date
◦ the time in Universal Coordinated Time (UCT)
◦ the altitude of the GPS antenna
◦ other information that can be used to diagnose network problems.
Alternative to GPS Sync
A Canopy link can operate without GPS sync, but cannot operate without sync. The
alternative to GPS sync is to configure the AP or BHM in the link to generate a sync pulse
to pass to the SM or BHS, respectively. Depending on the RF environment in which the
link operates, this latter alternative may or may not be plausible.
For example, in Figure 23, AP4
◦ is not synchronized with any of the other APs.
◦ is transmitting nearby the other APs while they are expecting to receive SM
transmissions from a maximum distance.
Release 8 Overview of Canopy Networks
March 200 Through Software Release 6.
Issue 2, November 2007 Draft 5 for Regulatory Review 94
Figure 23: One unsynchronized AP in cluster
The result is self-interference. In this scenario, the self-interference can be avoided only
by synchronizing the TDD transmit cycles of all APs that operate in the same frequency
band.
An AP that is isolated by at least 5 miles (8 km) from any other Canopy equipment, or a
BHM in an isolated standalone BH link can generate and pass sync pulse without GPS
timing and not risk that interference will result from the generated sync. In any other type
of Canopy link, sync should be derived from GPS timing.
NOTE:
The OFDM Series BHMs generate their own sync. For more information about
these modules, see the user guides that support them. Titles are listed under
Products Not Covered by This User Guide on Page 34.
Advantage of GPS Sync
Although the embedded timing generation capability of the Canopy AP and BHM keeps a
precise clock, no trigger exists to start the clock at the same moment in each AP of a
cluster. So, the individual AP can synchronize communications between itself and
registered SMs, but cannot synchronize itself with other Canopy modules, except by GPS
timing (shown in Figure 24).

7.2.2 Passing Sync in a Single Hop
Network sync can be passed in a single hop in the following network designs:
◦ Design 1
1. A CMM provides sync to a collocated AP.
2. This AP sends the sync over the air to SMs.
◦ Design 2
1. A CMM provides sync to a collocated BH timing master.
2. This BH timing master sends the sync over the air to a BH timing slave.
7.2.3 Passing Sync in an Additional Hop
Network sync can be extended by one additional link in any of the following network
designs:
NOTE:
In each of these following designs, Link 2 is not on the same frequency band as
Link 4. (For example, Link 2 may be a 5.2-GHz link while Link 4 is a 5.7- or 2.4-
GHz link.)
◦ Design 3
1. A CMM provides sync to a collocated AP.
2. This AP sends the sync over the air to an SM.
3. This SM delivers the sync to a collocated AP.
4. This AP passes the sync in the additional link over the air to SMs.
This design is illustrated in Figure 25.

Wiring and configuration information for this sync extension is described under Wiring to
Extend Network Sync on Page 367.
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. (The sync
cable is described under Cables on Page 57.) 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.

8 MEETING LINK REQUIREMENTS
8.1 AP-SM LINKS
APs communicate with SMs using a point-to-multipoint protocol. An AP-SM link has lower
throughput and higher latency than a backhaul link for two reasons:
◦ Many endpoints are involved.
◦ The bandwidth request and reservation process consumes bandwidth.
In the 900-MHz frequency band range, round-trip latency is typically
◦ 40 msec with software scheduling.
◦ 15 msec with hardware scheduling.
In all other Canopy frequency band ranges, round-trip latency is typically
◦ 15 msec with software scheduling.
◦ 6 msec with hardware scheduling.
At range settings of greater than 40 miles (64 km) in the 900-MHz AP, more time elapses
between transmit and receive cycles to compensate for greater air delay. In each frame,
this reduces the number of data slots, which slightly reduces the aggregate throughput of
the link. However, the throughput is as predictable as in other Canopy point-to-multipoint
links.
Throughput is a factor of the Max Range parameter in the AP and is effective for all SMs,
regardless of their distance from the AP. Throughput includes all downlink data to all SMs
and all uplink data from all SMs that link to the AP. For throughput with hardware
scheduling, see Table 13 on Page 62.
End user perspective of throughput is based on both bandwidth in the sending direction
and the return of TCP acknowledgement packets in the other. Where sufficient downlink
bandwidth exists to support downlink traffic and overhead, transient traffic congestion in
the uplink can cause some TCP acknowledgement packets to be dropped, and the end
user to perceive a reduction in throughput. This can also occur with sufficient uplink
bandwidth and dropping acknowledgment packets in the downlink.
However, a Canopy network operator can optionally enable the Prioritize TCP ACK
parameter in the AP and BHM, giving these packets priority over other packet types.
This results in fewer of them being dropped.
The effects of changing network conditions on PTMP throughput are indicated in
Table 24.

NOTES:
1. For non 900-MHz APs, the AP accepts a Max Range value of up to 30
miles (48 km). See Max Range on Page 242.
2. To avoid a decrease of unnecessary proportion, set to not much further
than the distance between the AP and the furthest SM that registers in
the AP.
