NOTICES
Important Note on Modifications
Intentional or unintentional changes or modifications to the equipment must not be made unless under the express consent of the party
responsible for compliance. Any such modifications could void the user’s authority to operate the equipment and will void the
manufacturer’s warranty.
U.S. Federal Communication Commision (FCC) and Industry Canada (IC) Notification
This device complies with part 15 of the U. S. FCC Rules and Regulations and with RSS-210 of Industry Canada. Operation is subject
to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference
received, including interference that may cause undesired operation. In Canada, users should be cautioned to take note that high power
radars are allocated as primary users (meaning they have priority) of 5250 – 5350 MHz and 5650 – 5850 MHz and these radars could
cause interference and/or damage to license-exempt local area networks (LELAN).
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the U.S. FCC
Rules and with RSS-210 of Industry Canada. These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in
accordance with these instructions, may cause harmful interference to radio communications. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment on and off, the user is encouraged to
correct the interference by one or more of the following measures:
Increase the separation between the affected equipment and the unit;
Connect the affected equipment to a power outlet on a different circuit from that which the receiver is connected to;
Consult the dealer and/or experienced radio/TV technician for help.

Canopy can be configured to operate at a range of frequencies, but at this time, only channels from 5745 MHz through 5805 MHz of the
5.7 GHz product have been tested for compliance with relevant EC directives. Before configuring equipment to operate outside this
range, please check with your regulator.
Exposure Note
A Canopy module must be installed to provide a separation distance of at least 20 cm (7.9 in) from all persons. When adding the Canopy
reflector dish, the reflector dish must be installed to provide a separation distance of at least 1.5m (59.1 in) from all persons. When so
installed, the module’s RF field is within Health Canada limits for the general population; consult Safety Code 6, obtainable from Health
Canada’s website http://www.hc-sc.gc.ca/rpb.
In both configurations the maximum RMS power does not exceed 340mW.
The applicable power density exposure limit is 10 Watt/m2, according to the FCC OET Bulletin 65, the ICNIRP guidelines, and the
Health Canada Safety Code 6. The corresponding compliance distances referenced above have been determined by assuming worst-case
scenarios. The peak power density (S) in the far-field of a radio-frequency source with rms transmit power P and antenna gain G at a
distance d is
S=
P ⋅G
4π d 2
In the case of the Canopy SM without reflector, the gain is 8 dBi (a factor of 6.3), so the peak power density equals the exposure limit at
a distance of 13 cm for 2.4 GHz product and 10 cm for 5.2 and 5.7 GHz product. A power compliance margin of over 2 is artificially
introduced by setting the distance to a consistent 20 cm across all modules, giving a power compliance margin of x2.4 for 2.4 GHz
modules and x4 for 5.2 and 5.7 GHz modules.
In the case of the Canopy SM with reflector, the gain depends on frequency and ranges from 19 dBi (a factor of 80) for 2.4 GHz modules
to 26 dBi (a factor of 400) for 5.2 GHz Extended Range and 5.7 GHz modules, so the peak power density equals the exposure limit at a
distance of 10 to 80 cm. A power compliance margin is artificially introduced by defining a consistent compliance distance of 1.5 m
across all modules with reflectors, giving a power compliance margin of x10 for 2.4 GHz modules, x220 for 5.2 GHz Extended Range
modules, and x3.5 for 5.7 GHz modules. The compliance distance is greatly overestimated in this case because the far-field equation
neglects the physical dimension of the antenna, which is modeled as a point-source.

PRODUCT DESCRIPTION
Canopy Backhaul
Backhaul links provide point-to-point connectivity either as a standalone link or feeding an Access
Point cluster as part of a Canopy network.
Backhaul modules are available in 2.4, 5.2, and 5.7 bands and in both 10 and 20 Mbps. 2.4 and
5.7 backhauls can be used with reflectors on either or both ends. Regular 5.2 backhauls cannot be
used with reflectors in the US or Canada due to regulatory agency restrictions. Extended Range
(ER) 5.2 Backhauls have very low transmit power and it is recommended to use reflectors at both
ends.
The following table shows typical ranges for each type of backhaul.

When using Backhauls in standalone links, the type of Backhaul is selected based on RF
environment, throughput, and range needed. When using Backhauls in a network and co-locating a
BH with Access Points, the type of backhaul is usually selected based on having the BH in a
different band than the APs. In other words, if the APs are 5700s, the BH could be a 5200 or a
2400. If the APs are 2400s, the BH could be a 5200 or a 5700. While distance separation of 100
vertical feet (30 m) on a tower can allow co-locating APs and BHs from the same band, choosing
cross-band APs and BHs is usually the better choice.

Backhaul User Manual Draft for Regulatory Review
Page 11 of 55
LNK: The link LED displays the status of the Ethernet link to the Canopy module. The LED will be
constantly lit if there is an Ethernet link present. The LED is colored green.
ACT/4: The activity LED displays the status of any data activity on the Ethernet link. The LED will
flash (at no particular speed) when data is being transferred on the Ethernet link. The LED is
colored orange.
GPS/3: If the module is a backhaul timing master the GPS LED displays the status of the sync
pulse and is lit constantly when the pulse is being received. If the module is a backhaul timing
slave this LED is not utilized. The LED is red.
SES/2: The session LED is not used on the access point module. The LED is green.
SYN/1: The sync LED displays sync status. In short, this LED will lit all the time on an access
point module. The LED is orange.
PWR: The power LED displays the status of power to the module. The LED will be constantly lit if
power is applied correctly. The LED is red.
If the module is a backhaul timing slave and is not registered to a backhaul timing master then the
SYN/1, SES/2, and GPS/3 LEDs will cycle on and off from left to right.
Alignment Mode
When a backhaul timing slave module is placed in Alignment Mode the LEDs take on an entirely
different purpose. The power LED will still indicate whether or not power is applied to the module.
The 6 LEDs and are turned into a 6-position bar graph. The more LEDs that are lit, the better the
RSSI and Jitter values the module is seeing. The colors of the LEDS have no particular meaning
other than to assist is distinguishing one position from the next. See Alignment section for more
information.

BACKGROUND INFORMATION ON NETWORKING
Computers are assigned IP addresses by network operators, which have two methods available,
static or dynamic IP addressing. The user of this document will need to understand how IP
addressing is done at their particular location.
All Canopy radio products (Subscriber Modules, Access Point Modules, and Backhaul Modules)
have the default IP address of 169.254.1.1. For a computer to talk to Canopy, as it comes from the
factory, either of the following conditions must be met:
•
•
If the computer is not configured for DHCP, then it has to have a static IP address on the
169.254 network (i.e. 169.254.1.5)
If the computer is configured for DHCP, then it will automatically obtain an IP address on
the 169.254 network after minute or two as long as it is not connected to the network.

SYSTEM OVERVIEW AND SITE PLANNING
Definitions:
Backhaul Timing Master – a module that is used in a point-to-point link. This module controls the
air protocol and configurations for the link.
Backhaul Timing Slave – a module that is used in a point-to-point link. This module accepts
configuration from the master module.
Cluster Management Module – a module that contains power, GPS timing, and networking for
backhaul timing master(s). Can also be utilized in conjunction with an access point cluster.
In the Canopy System, the point-to-point link is achieved utilizing backhaul modules in either the
2.4 GHz, 5.2 GHz, or 5.7 GHz band. The backhaul modules utilize passive reflector to achieve
distances of up to 35 miles (56 km). Note: Distances may vary based on terrain and other line of
sight issues.
In its basic form the point-to-point link is made up of a backhaul timing master and a backhaul
timing slave. The cluster management module is key to the operation of the Canopy System.
Backhaul timing masters must be connected to a cluster management module so that a GPS timing
pulse can synchronize their transmission cycles. If one backhaul timing master module were to not
be synchronized then it may be transmitting during a receive cycle of the other modules and cause
de-sense. This is also true of the Canopy access point modules.
The following are some simple network diagrams of the proper way to layout single and multihopped point-to-point links.
Example 1: The single hop.

From these diagrams it can be seen that at each location there is only like kind backhaul modules.
In all cases where there is a cluster management module an access point cluster could be placed
also. In the case of Example 2, a cluster management module could be placed where the two
backhaul timing slaves are located to install an access point cluster; however the timing slaves do
not need to be connected to he CMM for timing purposes.
Site Selection Criteria
There are various issues that need to be taken into consideration when choosing a location for
the network infrastructure. The following is a list of those considerations. There may be others
as each site is unique.
•
Height is essential when installing a Canopy backhaul module. The Canopy backhaul
module must be mounted higher than other objects located immediately around it such as
trees, buildings, tower legs, etc.
•
There should be no obstructions that will interfere with the unit’s internal antenna. The area
immediately in front of an access point module must be clear of all obstructions.
•
Will the installation area change in the future? Will there be structures high enough to
Backhaul User Manual Draft for Regulatory Review
Page 15 of 55
interfere with the signal? Will trees grow into the line-of-sight path?
•
When possible, avoid high RF energy sites. Do not place Canopy equipment in the same
plane as other RF equipment.
•
The means used by the installer to attach the backhaul module to the tower, rooftop, or pole
should be rigid and should not move or flex due to wind or other vibrations.
•
Tower availability - will a tower have to erected?
•
There must be grounding systems available for protection of the Canopy equipment.
•
Lighting arrestors are required in installation area to transport lightning strikes away from
equipment.
Backhaul User Manual Draft for Regulatory Review
Page 16 of 55
General Considerations
•
Fresnel Loss - The Fresnel Zone is a theoretical area around the line of sight of an antenna
transmission that can affect the signal strength. Objects that penetrate the Fresnel Zone can
cause fading of the transmitted signal. This fading is caused by the cancellation of the signal
due to out-of-phase reflections. An unobstructed line of sight is important, but it is not the
only determination of an adequate placement. Even though the path has a clear line of
sight, if obstructions (such as terrain, vegetation, metal roofs, cars, etc.) penetrate the
Fresnel zone, there will be signal loss. The following illustrates a Fresnel zone.
Fresnel Zone
D1
Transmitter
•
•
•
D2
Receiver
Free Space Path Loss – As an RF signal travels through space, it is attenuated by the
distance from the initial transmission point. The farther away from the transmission point,
the weaker the RF signal.
Foliage Loss – Tree and plant foliage will cause additional signal loss. Seasonal density,
moisture content of the foliage, and other factors such as wind may change the amount of
loss. Caution should be used when a link may transmit though this type of environment.
Carrier to Interference – describes how much signal advantage must be engineered into
the radio link to tolerate an interfering transmission.
•
How many point-to-point links are being planned for deployment? Each backhaul timing
master will need to utilize a cluster management module for seamless operation within the
entire Canopy System.
•
How will the access point clusters be deployed relative to planned point-to-point links?
Backhaul User Manual Draft for Regulatory Review
Page 17 of 55
Channel Plans
Whether using 2.4, 5.2, or 5.7 GHz modules, frequencies should never be placed closer
than 20 MHz. 5.2 and 5.7 GHz modules allow the operator to chose frequencies every 5
MHz. 2.4 GHz modules allow the operator to chose frequencies every 2.5 MHz. This is
so that in the event of co-location with other equipment the operator can customize the
channel layout for interoperability.
Backhauls and APs operating in the same frequency band (within the 2.4 GHz band, within the 5.2
GHz band, or within the 5.7 GHz band) need 100 feet (30 m) of physical separation, as their
different transmit and receive frame structures otherwise would cause interference.
2.4 GHz Recommended Frequencies
The following are the 3 non-overlapping channels that are recommended by the Canopy team for
use with the backhaul module:
•
•
•
2.415 GHz
2.435 GHz
2.4575 GHz
Note this gives 20 MHz of separation between one pair of channels, and 22.5 MHz of separation
between the other pair. Depending on the RF environment you are operating in, you may want to
put the middle channel at 2.4375 GHz and give additional separation between it and the 2.435 GHz
channel, or move the top channel down to 2.455, or the bottom channel up to 2.4175, as long as
you maintain at least 20 MHz of separation between channels. You can use the Spectrum Analysis
feature in an SM or BHS, or a standalone spectrum analyzer, to help evaluate the RF environment
and guide you in site-specific frequency engineering.
5.2 GHz Recommended Frequencies
The following are the 3 non-overlapping channels that are recommended for use with the backhaul
module:
•
5.275 GHz
•
5.300 GHz
•
5.325 GHz
5.7 GHz Recommended Frequencies
The following are the 6 non-overlapping channels that are recommended for use with the backhaul
module when the ISM frequencies are available:
•
5.735 GHz
•
5.755 GHz
•
5.775 GHz
•
5.795 GHz
•
5.815 GHz
•
5.835 GHz
20 Mbps backhaul modules have less “margin” at the edges of their 20 MHz channel. When using
Backhaul User Manual Draft for Regulatory Review
Page 18 of 55
20 Mbps Backhauls, consider using 25 MHz spacing if site engineering allows it, especially if you
are engineering backhauls with less than 6° directional separation.
Backhaul User Manual Draft for Regulatory Review
Page 19 of 55
Networking Information
The Canopy access point module will each use an IP address on the operator’s network. It is
recommended that the access point modules never be placed directly onto the Internet. IP
addresses may be assigned sequentially clockwise around an access point cluster for easier
manageability. The operator will also need to identify the appropriate subnet mask and network
gateway each of the modules.
From the factory, each access point module is assigned a unique MAC address and the following
default networking information:
•
•
•
IP address of 169.254.1.1
Subnet mask of 255.255.0.0
Network gateway of 169.254.0.0
Lightning Protection
•
The Canopy access point module, cluster management module, and GPS antenna must
be mounted at least 2 feet below the highest point at the site for lightning strike mitigation.
It is highly recommended that the site have a lightning protection system installed.
•
Ensure the location is properly grounded for lightning protection according to all applicable
national and local codes.
•
To protect operator equipment from surges on the Ethernet cable that is connected to the
Canopy System, the Canopy surge suppressor must be used.
Electrical Requirements
•
Specifications for the voltages and distance can be found in the Specification section of
this manual.
•
Make certain the installation conforms to the National Electrical Code (NEC), country and
local codes. If uncertain of code requirements, obtain the services of a licensed
electrician.

Reflector dishes
The passive reflector arm is molded to receive the plastic housing of the backhaul module. Use
stainless steel hose clamps to secure the module to the arm. The module is now properly aligned
within the reflector. The following figure shows this installation.

ADVANCED FEATURES
These features may be used in the Canopy System but are not required for basic operation.
Security - DES Encryption
Standard Canopy modules provide Data Encryption Standard (DES) encryption. DES is a secret
key encryption scheme using a 56 bit key. The basics of DES are that it performs a series of bit
permutations, substitutions, and recombination operations on blocks of data using a secret key.
On the Canopy system, encryption of the over the air link is enabled or disabled per Access Point
module or per Backhaul timing master module. The Canopy modules contain unique factory
programmed secret keys to establish the encrypted link. If an authentication key (must be the same
key on each end of the backhaul link) has been entered using the Backhaul Configuration page,
then that key is also used to establish the DES encryption key. Encryption does not affect the
performance or throughput of the system.
Security - AES Encryption
Motorola also offers Canopy products that provide Advanced Encryption Standard (AES)
encryption. Like DES, AES is a secret key encryption scheme, but AES uses the Rijndael algorithm
and 128 bit keys to establish a higher level of security than DES.
Due to the level of security provided by AES, the US government has established export controls
on communications products that use AES. These export controls may mean that outside of the US
AES products are only available in certain regions – check with your Canopy distributor or reseller
for availability in your area.
Canopy AES products run the same software as DES products, so the features available are the
same and work the same, The only exception is that the AES products provide AES instead of DES
encryption when enabled for encryption on the Configuration screen. All the interface screens,
Status pages, Configuration pages, etc. are identical. As new software features become available
on DES products, the same software and the same features will be available for AES products.
DES backhauls are available in both 10 Mbps and 20 Mbps signaling rates. AES backhauls are
only available with a 10 Mbps signaling rate.
Canopy DES products are not upgradeable to AES. To have the option of AES encryption, you
must purchase AES products.
Canopy AES products use a different FPGA load than DES products do. The AES FPGA will be
upgraded as needed to provide new features or services similar to the DES products.
The same as with DES, encryption of the over the air link is enabled or disabled per Access Point
module or per Backhaul timing master module. The Canopy modules contain unique factory
programmed secret keys to establish the encrypted link. If an authentication key (must be the same
key on each end of the backhaul link) has been entered using the Backhaul Configuration page,
then that key is also used to establish the AES encryption key.
Canopy AES products and DES products do not interoperate when enabled for encryption, as DES
and AES are different encryption schemes. An AES AP with encryption enabled can only
communicate with AES SMs, and similarly an AES Backhaul timing master module with encryption
enabled can only communicate with an AES Backhaul timing slave module. However, if encryption
Backhaul User Manual Draft for Regulatory Review
Page 22 of 55
is not enabled, AES modules can communicate with DES modules.
Branding
On each Canopy module, the web-based interface screens have a Canopy logo that can be
replaced with an operator’s company logo. The Canopy logo file is called canopy.jpg and the
replacement file must also be called canopy.jpg. The new file is transferred via FTP to the module
and then added to a special filesystem through a telnet session. The following command can be
used during a telnet session:
• addwebfile – add a custom logo file to the filesystem
• clearwebfile – clear the customer logo file from the filesystem
• lsweb – list the custom logo file and display the storage space available on the filesystem
The following is a sample FTP session:

INSTALLATION
The following steps are required to install the Canopy backhaul module:
•
Unpack the Canopy products
•
Configuration of the backhaul modules
•
Installation of the backhaul modules
•
Alignment
Unpack the Canopy Products
Upon receipt, carefully inspect all shipping boxes for signs of damage. If there is damage,
immediately notify the transportation company.
Unpack equipment, making sure that all ordered components have arrived. It is recommended that
you save all the packing materials. They can be used for transportation of the equipment to and
from installation sites.
Configuration of the Backhaul Modules
In all cases, when a configuration parameter is modified, the change must be saved and
the module must be rebooted.
All backhaul module, from the factory are configured as backhaul timing slaves. The following are
items that an operator will need to verify and/or configure for each module:
•
Will the module be a timing master or timing slave?
If it is a Timing Master
The are two methods that can be utilized to configure each of the backhaul timing masters. The
first method is to utilize the Quick Start feature of the product. For more information on Quick Start
see The Interface Screens. The second is to manually set each of the parameters.
•
Will the backhaul module need to generate its own sync pulse or will it receive it from the
cluster management module?
•
The operator will assign a RF frequency for the module to transmit.
•
The operator will assign an IP address to the module for the network it will be installed on
and assign an appropriate subnet mask and network gateway.
•
The operator must configure the appropriate color code on the backhaul timing master
module so that the backhaul timing slave module can register with it. The color codes
must match for registration.
If it is a Timing Slave
•
The backhaul timing slave module will utilize a network accessible IP address for its LAN
IP address. From the factory, the timing slave module is programmed to utilize an IP
address of 169.254.1.1. Continually, the appropriate subnet mask and default gateway
must be utilized for the operator network infrastructure.
•
The operator must configure the appropriate color code on the backhaul timing slave
Backhaul User Manual Draft for Regulatory Review
Page 25 of 55
module so that it can register with a backhaul timing master module. The color codes must
match.
The operator can prevent unauthorized users from connectig to the backhaul module’s web based
interface by assigning a password. There is no default password and password protection is turn
off is turn off from the factory.
Passwords can be from 1 to 16 characters. Any combination of characters is allowed, except for
these special characters: “ , . ‘ { } / \ ; : [ ] ( ) ` ~
NOTE: If the operator forgets either the password or the IP address for the module, a Canopy
default plug can be used to regain access. See Configuration for information on the default plug.
There are two types of passwords that can be configured: display-only or full-access. The displayonly password allows the operator to view the module’s current status. The full-access password
allows the operator to view the module’s current status and change its configuration. By viewing
the red lettering to the right of the entry fields, the operator can discern that a password is set.
The operator can enter in information about the Site Name, Location, and Contact. This is optional.
See the Access Point Cluster and Cluster Management Module user manual for details
on configuration and installation of a cluster management module.
Installation of the equipment
When power is applied to a Canopy module or the unit reset via the web-based interface, the
module will take approximately 25 seconds to boot up. During this boot up time, power on selftests and other diagnostics are being performed.
The following steps are needed to install the Canopy equipment:
•
Remove the base cover from all Canopy backhaul timing master modules to be installed.
•
Remove the GPS sync cable knockout from the base cover with needle-nose pliers.
•
Mount the backhaul modules:
•
•
The modules can be mounted in a variety of locations, choose the best location
for your particular application. Mounting can be done by utilizing stainless steel
hose clamps or another equivalent fastener.
Route the Ethernet cable from the backhaul module to the cluster management module.
The Ethernet cables use RJ-45 connectors (standard Ethernet) that connect to
matching ports within the cluster management module.
A total of 8 ports are available on the cluster management module, to
accommodate a combination of access point modules and backhaul timing master
modules.
Route the GPS sync (serial) cable from the backhaul timing master module to the cluster
management module.
The GPS sync cables use 6 conductor RJ-11 connectors that connect to matching
ports within the cluster management module.
Backhaul User Manual Draft for Regulatory Review
Page 26 of 55
•
Replace the base cover on all of the backhaul modules.
Alignment
•
If the backhaul modules are not utilizing passive reflectors, then visually align the units.
If the backhaul modules are utilizing passive reflectors then visually align if possible or utilize
compass headings and initiate step 1 in the following process
IF USING A 5.7 GHz SUBSCRIBER MODULE: the passive reflector will
change the radiated pattern to 6° horizontal by 6° vertical.
IIF USING A 2.4 GHz SUBSCRIBER MODULE: the passive reflector will
change the radiated pattern to 17° horizontal by 6° vertical.
1. Lock down timing master module
2. On the timing slave module, utilize RSSI only mode of alignment web page:
•
Choose the frequency to monitor from the pick list (this would be the same
frequency that the backhaul timing master module is transmitting on)
•
Click the radio button to highlight “Enable” on RSSI Only mode
•
Click “Enable Aiming Mode”
The module will now report back the level of RF energy present at that specific
frequency. To refresh the screen, click the Enable Aiming Mode button as appropriate
or configure the web page auto-refresh option. The minimum RSSI level for a link is
greater than 700.
3. When RSSI value is above minimum, disable RSSI Only mode and monitor the Status
web page:
a. Watch for “Syncing”, then “Registering”, then “Registered”. When the unit is
registered, move on to Step 4.
4. While monitoring RSSI and Jitter, at the incrementally move the timing slave module in
the vertical plane. Observe where the values are at their best and lock down the unit.
Now, incrementally move the timing slave module in the horizontal plane. Observe
where the values are at their best and lock down the unit. Alignment is complete when
reported values are at their best and the unit is registered.
5. If necessary, incrementally move the timing master module a couple (2-3) degrees and
go back to Step 1.

CABLING
It is strongly recommended to use shielded cable for all Canopy infrastructure cabling associated
with Backhauls, Access Points, and Cluster Management Modules. The environment these
modules operate in often has significant or unknown or varying RF energy, and experience has
been that the additional cost of shielded cabling is more than compensated by predictable
operation and reduced debugging and support costs.
The following information describes the wiring standards for installing a Canopy system. All
diagrams use the EIA/TIA 568B color standard.
Currently shipping modules and most modules in the field auto-sense the Ethernet cable type –
either RJ-45 straight-thru cable or RJ-45 crossover cable can be used to connect a network
interface card (NIC), hub, router, or switch to a module.
The following table shows MAC Addresses of Auto-sensing modules:
MAC Address (ESN)
Non-auto-sensing
Auto-sensing
2.4 Modules
All
5.2 Modules
≤ 0a003e0021c8
≥ 0a003e0021c9
5.7 Modules
≤ 0a003ef00f79
≥ 0a003ef00f7a
Very early modules did not auto-sense. In cases where older, non-auto-sensing
modules are used:
• When connecting a Canopy device directly to a network interface card (NIC)
use a RJ-45 straight-thru cable.
• When connecting a Canopy device directly to a hub, switch, or router use a
RJ-45 crossover cable.
When using the Canopy AC wall adapter the +V is +11.5VDC to +30VDC with a nominal value of
+24 VDC, and the maximum Ethernet cable run with the AC wall adapter is 328 feet (100 meters).

THE INTERFACE SCREENS
The Canopy backhaul module contains a series of web pages that are used to interface to the unit.
The following is a quick reference to interface screens. Note: These screens are subject to
change by subsequent software versions. To access the web based interface you first must be on
a computer that is in some way connected to the access point module. This can be done either
directly or through a network. Enter the IP address of the backhaul module (default is 169.254.1.1)
into the address bar of your browser and hit enter on your keyboard.
The backhaul module will have two different sets of interface screens, one for the timing master
and one for the timing slave. The master and slave’s interface screens are very similar to that of
the access point module and subscriber module respectively.
The following web based interface pages are accessible:

THE TIMING MASTER
Quick Start
The Canopy System consists of a family of highly flexible, fixed wireless access devices that can
be put into service quickly and with a minimal configuration. The Quick Start is a wizard that walks
the operator through that configuration. To place an access point module into operation, only three
parameters need to be configured:
•
•
•
RF Carrier Frequency
Synchronization
Network IP Address
Each of the pages in the Quick Start will explain a little about Canopy and ask the operator for a
choice that best addresses the network requirements. At the end, the operator will be given the
opportunity to review the configuration selected and save it to non-volatile memory. None of the
changes made prior to saving the configuration will affect the system so experimentation with the
interface is encouraged.
Backhaul User Manual Draft for Regulatory Review
Status Page
The Status page contains information on the operation of the product. It is the default web page.
The following parameters are displayed:
Device Type: displays the type of Canopy module that is currently being viewed. This field will let
the operator know the frequency band of the module, the protocol that it is utilizing, and the MAC
address of the module. The frequency band can either be in the 5.2 GHz or 5.7 GHz band.
Software Version: displays the version of the software that is currently loaded into the module.
Please make note of this information when obtaining technical support.
FPGA Version: displays the version of the FPGA (field programmable gate array) that is currently
loaded into the module. Please make not of this information when obtaining technical support.
Uptime: displays the length of time the module has been operating since power was applied.
System Time: displays the current time. If the access point module is connected to a Cluster
Management Module (CMM) then the time will be Greenwich Mean Time (GMT). Any subscriber
module that registers to the access point module will inherit the system time.
Ethernet Interface: displays the configuration of the Ethernet interface on the module.
Registered SM Count: displays the number of subscriber modules currently registered to the
access point module.
GPS Sync Pulse Status: displays the current status of the type of synchronization the access
point module is receiving. There are 3 values that could be displayed:
• Generating sync: If the module is set to generate its own sync pulse then this message will
be displayed.
• Receiving Sync: If the module is set to receive a sync pulse from an outside source (not
itself) and is actually receiving the pulse then this message will be displayed.
Backhaul User Manual Draft for Regulatory Review
•
ERROR: No Sync Pulse: If the module is set to receive a sync pulse from an outside
source (not itself) and it is currently not receiving the pulse this message will be displayed.
When this message is displayed the access point module will turn its transmitter off so as
to not create any self-interference within the Canopy System.
Radio Slicing Value: displays information to be used be Canopy technical support.
Radio Transmit Gain Setting: displays information to be used by Canopy technical support.
Site Name: displays information relating to the name of the physical module. This parameter can
be set by the operator on the Configuration web page. This information is set into the sysName
SNMP MIB-II object and can be polled via a SNMP management server.
Site Contact: displays contact information for the physical module. This parameter can be set by
the operator on the Configuration web page. This information is set into the sysContact SNMP MIBII object and can be polled via a SNMP management server.

Configuration
The Configuration web page contains information and configurable parameters pertaining to the
operation of the product. The first line of information on the Configuration screen is a repeat of the
Device Type from the Status web page. The following are the parameters and their descriptions.
Timing Mode: choose whether this module will be a timing master or a timing slave. If the
operator is changing this mode, change only this parameter, save the changes and reboot. Upon
reboot different set of web based interface pages will present themselves and offer the operator
different manageable as well as configurable features.
Sync Input: choose the type of synchronization that this access point module will utilize. If “Sync
to Received Signal” is chosen, then it is assumed that:
• this access point module it connected to a Cluster Management Module and will be
receiving a sync pulse via GPS
• this access point module is connected to another access point module that is generating its
own sync pulse.
If “Generate Sync Signal” is chosen then it is assumed that:
• this access point module is a stand-alone module with no other access point modules
within a 5 mile radius.
• this access point module is generating the sync pulse for a cluster of access point modules
and there are no other access point modules within a 5 mile radius.
Link Negotiation Speeds: choose the type of link speed desired for the Ethernet connection. The
default for this parameter is for all the choices to be checked.
RF Frequency Carrier: choose the frequency that the module will transmit on. The default from
the factory is to have this parameter set to none.
Downlink Data: choose the percentage of the aggregate throughput that is needed for the
downlink (i.e going from the backhaul timing master to the backhaul timing slave). For example, if
the aggregate throughput on the backhaul master is 6 Mbits, then configuring this parameter for
75% will allocate 4.5 Mbits for the downlink and 1.5 Mbits for the uplink. The default for this
parameter is 50%.
Backhaul User Manual Draft for Regulatory Review
LAN 1 IP: enter in the IP address that will be associated with the Ethernet connection on this
module. The default address is 169.254.1.1. If the IP address is forgotten, the operator will need
physical access to the module and will need to create a Canopy “default plug”. See steps at the
end of this section for use of a default plug.
LAN1 Subnet Mask: enter in an appropriate subnet mask for the module to “talk” on the network.
The default value for this parameter is 255.255.255.0
Default Gateway: enter in the appropriate gateway for the module to “talk” on the network. The
default for this parameter is 169.254.1.1.
Private IP: the default for this parameter is 192.168.101.1. It is recommended that the operator
not change this parameter. A flat, class C subnet is used to communicate with each of the
subscriber modules that have registered. The access point utilizes a combination of the private IP
and the logical unit ID (LUID) of the subscriber module.
For example, if there are two subscriber modules (LUID 2 and LUID 3) registered to an access
point module, then the access point uses the following to communicate to each:
Unit
access point module
subscriber module 1
subscriber module 2
LUID
Private IP
192.168.101.1
192.168.101.2
192.168.101.3
If the private IP address is changed then it must designate a Class C subnet that s not utilized for
anything else and the address must be in the form of xxx.xxx.xxx.1, where 1 is the last octet of the
address.
Color Code: enter in a value (0-254). The color code on the subscriber module and the access
point module must match in order for registration to occur. Color code is not a security feature. It
is a means for the Canopy System operator to segregate an individual network or neighbor Canopy
networks. Also, color code can be used to force a subscriber module to only register to a specific
access point module even though the subscriber module may be able to see multiple access point
modules. The default value for this parameter is 0 on all Canopy modules.
Sector ID: choose an ID number to give to this access point module. This parameter does not
affect the operation of the module in any way. Its purpose is just another means to identify the
access point module. When observing a subscriber module’s AP Eval Data web page, the sector
ID is one of the distinguishing fields present to help the operator understand what access point
module is seen. It is recommended that when constructing an access point cluster (2-6 modules)
that each sector be given a different ID and that the pattern be repeated throughout the entire
Canopy System for manageability.
Display-Only Access: enter the same password in both fields for verification. The display-only
password, when used, will allow only view activities to the module. When the display-only
password is set and not the full-access password, the display-only password will be tied to telnet
and FTP sessions to the module. If the full-access password is also set then it has precedence on
the telnet and FTP sessions. If the password is forgotten, the operator will need physical access to
the module and will need to create a Canopy “default plug” to override the unit. See steps at end of
section for use and creation of a default plug.
Full Access: enter the same password in both fields for verification. The full-access password,
Backhaul User Manual Draft for Regulatory Review
when used, will allow view and change activities to the module. When the full-access password is
set, the password will also be tied to telnet and FTP sessions to the module. When prompted for
the password via the web-based interface, there is no username required; however when prompted
for the password via a telnet or FTP session, the user that MUST be used is “root”. If the password
is forgotten, the operator will need physical access to the module and will need to create a Canopy
“default plug” to override the unit. See steps at end of this section for use of a default plug.
Webpage Auto Update: enter time period (in seconds) desired to have the web browser refresh
the web-based interface. The default setting is 0, which will cause the web-based interface to
never refresh.
Airlink Security: choose the type of air link security that is to be utilized on this access point
module. There are two choices:
• Normal: If utilizing this mode there is no encryption on the air link. This is the default
operation.
• DES: If utilizing this mode the air link is encrypted using single DES.
Bridge Entry Timeout: choose the appropriate bridge timeout for correct network operation with
existing network infrastructure. It is important that this parameter be set for a longer time period
than the ARP (address resolution protocol) cache timeout of the router being used to feed the
network. Note: Failure to properly configure this may lead to temporary loss of
communication to specific end users.
AP Background BER Mode: choose to have this feature turned on or off. Bit Error Rate (BER)
mode will allow an operator another means to verify the functionality of a link. When BER mode is
turn on a bit error rate can be read on the subscriber side to determine the quality of a registered
link. If the access point module is in a cluster with other modules then this parameter on all units
must be set exactly the same. Continually, when this feature is on the aggregate available
bandwidth will decrease by ~200 Kbps.
Community String: enter a string that will allow a SNMP management server accessibility to the
SNMP information. There must not be any spaces in the community string. The default for this
parameter is “Canopy”.
Accessing Subnet: enter the network that will be allowed to access SNMP information from the
canopy module. There are two pieces of information needed:
• The network in the form of xxx.xxx.xxx.xxx
• The CIDR (Classless Interdomain Routing) prefix length in the form of /xx
An example would be 198.32.0.0/16 where /16 is a subnet mask of 255.255.0.0. An Internet
search on Classless Interdomain Routing will provide greater detail on this subject for the
inexperienced network operator. The default is to allow all networks access.
Trap Address: enter in an IP address (xxx.xxx.xxx.xxx) of an SNMP management server where
trap information can be sent. A trap is a way for the module to tell the monitoring system that
something has happened. The following are scenarios where traps would be sent:
• after a reboot of the module
• if a SNMP management server tried to access agent information and supplied the wrong
community string, wrong SNMP version number, or came from the wrong accessing
subnet.
Site Name: enter information relating to a name given to the physical module. This parameter will
set the supplied information into the sysName SNMP MIB-II object and can be polled by a SNMP
Backhaul User Manual Draft for Regulatory Review
management server. The buffer size for this field is 128 characters.
Site Contact: enter contact information relating to the module. This parameter will set the
supplied information into the sysContact SNMP MIB-II object and can be polled by a SNMP
management server. The buffer size for this field is 128 characters.
Site Location: enter information relating to the physical location of the module. This parameter
will set the supplied information into the sysLocation SNMP MIB-II object and can be polled by a
SNMP management server. The buffer size for this field is 128 characters.
Save Changes: by clicking on this button, any changes that have been made on the Configuration
page will be committed to flash memory and will take effect after the next module reboot.
Undo Save Changes: by clicking on this button, any changes that have been made and not
committed through a reboot of the module.
Set to Factory Defaults: depressing this button will change all of the configurable parameters (all
of which are contained on the Configuration page) back to their factory settings.
Reboot: depressing this button will reboot the module.
Canopy Default Plug
When inserted, the default plug brings the module up with a default configuration. This allows the
operator to regain control of a module, which may be using an IP address and/or password that
has been forgotten. The default plug will also override the passwords for access and change
control and set the LAN1 IP address back to 169.254.1.1. This does not, by itself, change any
configuration, rather, it allows the operator to attach to the module using the default configuration
so that they can read the actual non-default values and set them accordingly.
The following steps outline the creation of a default plug (this plug can also be purchase for a
nominal fee at http://www.best-tronics.com/motorola):
•
•
Obtain a RJ-11, 6-pin connector and a small length of CAT 5 cable.
Pin-out all 6-pins according the following diagram and then short (i.e. solder) together
pins 4 and 6 on the other end. Remaining wires should not be connected to anything.
The following diagram shows the wiring of a default plug:
•
pin 1 →
pin 2 →
pin 3 →
pin 4 →
pin 5 →
pin 6 →
white / orange
white / green
white / blue
green
blue
orange
solder to orange
solder to green
Insert “default plug” in the GPS sync port of the module and apply power to the module
via its Ethernet cable.
When the module is booted up (power applied) it will be in default mode where the IP address will
be 169.254.1.1 and the passwords will be blank. All other configurations will have been preserved.

Sessions
The Session web page contains information on each of the subscriber modules that has registered
to the access point module. For each of the subscriber modules certain bits of information are
shown on this web page. An example of such information is:
LUID: 002 : MAC: 0a-00-3e-00-02-2f State: IN SESSION
Software Version : CANOPY 3.1 Aug 21 2002 13:52:12
FPGA Version : 08200207
Session Timeout: 7, AirDelay 5
Session Count: 2, Reg Count 2, Re-Reg Count 2
Average RSSI: 1842, Last RSSI: 1873
Average Jitter: 6, Last Jitter: 5
Descriptions of the parameters that are useful for managing and troubleshooting a Canopy System
are:
LUID: displays the logical unit ID of the subscriber module. As each subscriber module registers
to the access point module it is assigned a LUID. The LUID range starts at 2. If a subscriber
module were to lose its registration with the access point and then regain the registration it will
retain the same LUID, as long power has not cycled on the access point module.
MAC: displays the MAC address (or electronic serial number) of the subscriber module.
State: displays the current status of the subscriber module. There are two states:
• IN SESSION: the subscriber module is currently registered to the access point module.
• IDLE: the subscriber module was registered to the access point module at one time, but is
not currently.
Software Version: displays the version of software that is running on the subscriber module. If
this parameter is not present, then a software version prior to release version 3.1 is on that module.
FPGA Version: displays the version of FPGA that is running on the subscriber module. If this
parameter is not present, then a FPGA version prior to release version 082002 is on the module.
AirDelay: displays the distance of the subscriber module from the access point module. The
number presented needs to be multiplied by 49 to convert the number to feet.
Session Count: displays the number of sessions that this subscriber module has had with the
access point module. If this value is excessive large compared to other subscriber modules
registered with this access point, there may be an issue with the installation of the subscriber.
Reg Count: displays the number of registration request messages the access point module has
seen from the subscriber module. If this value is excessive large compared to other subscriber
modules registered with this access point, there may be an issue with the installation of the
subscriber.
Re-Reg Count: displays the number of registration request messages the access point module
has seen from the subscriber module that is already in session. If this value is excessive large
compared to other subscriber modules registered with this access point, there may be an issue
with the installation of the subscriber.
Average RSSI: displays the average RSSI value for the subscriber module.
Last RSSI: displays the last RSSI value for the subscriber module.
Backhaul User Manual Draft for Regulatory Review
Average Jitter: displays the average Jitter value for the subscriber module.
Last Jitter: displays the last Jitter value for the subscriber module.
GPS Status
The GPS Status web page displays information about latitude, longitude, height, satellites seen
and tracked when the access point module is configured to sync to received signal and is
connected to a Cluster Management Module.
Ethernet Stats
The Packet Stats web page reports TCP throughput and error information for the Ethernet
connection of the subscriber module. The following definitions are available:
inoctets count: displays the total number of octets received on the interface, including framing
characters.
inucastpkts count: displays the total number of subnetwork-unicast packets delivered to a higher
layer protocol
innucastpkts count: displays the total number of non-unicast (i.e. subnetwork-broadcast or
subnetwork-multicast) packets delivered to a higher layer protocol.
indiscards count: displays the total number of inbound packets which were chosen to be
discarded even though no errors had been detected to prevent their be deliverable to higher layer
protocol. One possible reason to discard could be to free up buffer space.
inerrors count: displays the total number of inbound packets that contained errors preventing
them from being delivered to a higher layer protocol.
inunknownprotos count: displays the total number of packets received via the interface which
were discards because of an unknown or unsupported protocol.
outoctets count: displays the total number of octets transmitted out of the interface, including
framing characters.
outucastpkts count: displays the total number of packets that higher-level protocols requested be
transmitted to a subnetwork-unicast address, including those that were discarded or not sent.
outnucastpkts count: displays the total number of packets that higher-level protocols requested
be transmitted to a non-unicast (i.e. subnetwork-broadcast or subnetwork-multicast) address,
including those that were discarded or not sent.
outdiscards count: displays the total number of outbound packets which were chosen to be
discarded even though no errors had been detected to prevent their being transmitted. One
possible reason for discarding such a packet could be to free up buffer space.
outerrrors count: displays the total number of outbound packets that could not be transmitted
because of errors.
RxBabErr: displays the total number of receiver babble errors.
Backhaul User Manual Draft for Regulatory Review
EthBusErr: displays the total number of Ethernet bus errors on the Ethernet controller.
CRCError: displays the total number of CRC errors on the Ethernet controller.
RxOverrun: displays the total number of receiver-overrun errors on the Ethernet controller.
Late Collision: displays the total number of late collisions on the Ethernet controller. A normal
collision occurs during the first 512 bits of the frame transmission. If a collision occurs after the 512
bit times, then it is considered a late collision. A late collision should be taken as a serious network
problem, since it causes the frame being transmitted to be discarded. The most common cause of
late collisions is a mismatch between duplex configurations at each end of a link segment.
RetransLimitExp: displays the total number of retransmit limit expirations.
TxUnderrun: displays the total number of transmission-underrun errors on the Ethernet controller.
CarSenseLost: displays the total number of carrier sense lost errors occurred on the Ethernet
controller.
Expanded Stats
Clicking on the Expanded Stats link will display a number of pages of statistics that are maintained
by the Canopy module. Canopy Technical Support may ask the operator for specific information in
this section when troubleshooting an issue.

THE TIMING SLAVE
Status
The Status page contains information on the operation of the product. It is the default web page.
The following parameters are displayed:
Device Type: displays the type of Canopy module that is currently being viewed. This field will let
the operator know the frequency band of the module, the protocol that it is utilizing, and the MAC
address of the module. The frequency band can either be in the 5.2 GHz or 5.7 GHz band. The
protocol for a subscriber module must be multipoint. The MAC address will be in the following
format, 0a-00-3e-xx-xx-xx.
Software Version: displays the version of the software that is currently loaded into the module.
Please make note of this information when obtaining technical support.
FPGA Version: displays the version of the FPGA (field programmable gate array) that is currently
loaded into the module. Please make not of this information when obtaining technical support.
Uptime: displays the length of time the module has been operating since power was applied.
System Time: displays the current time, which is inherited from the Canopy System via the
registration to an access point module. When the module is registered to a Canopy System where
a Cluster Management Module (CMM) is being utilized the time is displayed in Greenwich Mean
Time (GMT).
Ethernet Interface: displays the configuration of the Ethernet interface on the module.
Session Status: displays the current session state the module is in. There are four (5) options
that will display in this field, scanning, syncing, registering, registered, and alignment
•
Scanning – module is cycling through the RF frequencies that it is configured to scan and looking for

an access point module.
Syncing – module is attempting to synchronize timing to a single access point module
Registering – module sent a request for registration and is awaiting a response
Registered – module is locked on to a specific access point module and ready to transmit and
receive data packets
Alignment – module is in alignment mode
RSSI: displays the current value for the Radio Signal Strength Indicator. This parameter will only
display information when the module is registered to an access point module and the value is only
updated by either refreshing the web browser screen or configuring the Canopy module to autorefresh (see Configuration web page.) An acceptable RSSI value for a registered link is greater
than 700; however it is important to view this value in conjunction with the Jitter value.
Jitter: displays the current value for the quality of the received signal. This parameter will only
display information when the module is registered to an access point module and the value is only
updated by either refreshing the web browser screen or configuring the Canopy module to autorefresh (see Configuration web page.) The value range for Jitter is 5-15, with the quality being
better on the low end of the scale. Jitter must be below 9 for a link to be of acceptable quality.
Air Delay: display the distance from the subscriber module to the registered access point module.
At close range, 0-200 feet, the distance will not report accurately.
Radio Slicing Value: displays information to be used be Canopy technical support.
Radio Transmit Gain Setting: displays information to be used by Canopy technical support.
Site Name: displays information relating to the name of the physical module. This parameter can
be set by the operator on the Configuration web page. This information is set into the sysName
SNMP MIB-II object and can be polled via a SNMP management server.
Site Contact: displays contact information for the physical module. This parameter can be set by
the operator on the Configuration web page. This information is set into the sysContact SNMP MIBII object and can be polled via a SNMP management server.

Configuration Page
The Configuration web page contains information and configurable parameters pertaining to the
operation of the product. The first line of information on the Configuration screen is a repeat of the
Device Type from the Status web page. The following are the parameters and their descriptions.
Timing Mode: choose whether this module will be a timing master or a timing slave. If the
operator is changing this mode, change only this parameter, save the changes and reboot. Upon
reboot different set of web based interface pages will present themselves and offer the operator
different manageable as well as configurable features.
Link Negotiation Speeds: choose the type of link speed desired for the Ethernet connection. The
default for this parameter is for all the choices to be checked.
Custom RF Frequency Scan Selection (SM) List: Choose the frequencies that the subscriber
module will scan when looking for a Backhaul – timing master. For 5.2 and 5.7 GHz modules, 20
MHz wide channels are centered every 5 MHz. The default for this parameter for 5.2 and 5.7 GHz
modules is to scan all available frequencies – all check boxes are selected by default, For 2.4 GHz
modules, 20 MHz wide channels are centered every 2.5 MHz. The default for this parameter for 2.4
GHz modules is to scan 2415 MHz, 2435 MHz, and 2457.5 Mhz – only those 3 check boxes are
selected by default.
Select 2.4 GHz scan frequencies at least 5 MHz apart. Do not simply select all
frequencies by checking every box, like you might do with the 5.2 and 5.7 GHz SMs.
Canopy gives you checkboxes in the 2.4 GHz band for channels centered every 2.5
MHz, so you have flexibility for RF engineering based on your local RF environment.
However, if you select scan frequencies only 2.5 MHz apart (in other words, if you check two boxes
in sequence), there is potential for the BHS to successfully register to an BHM that is actually
transmitting at a frequency 2.5 MHz higher as it scans up the selected frequencies. Registration
may be successful, but the link is not as good as if it had registered 2.5 MHz higher, on the actual
BHM frequency. The 5 MHz spacing for channels on 5.2 and 5.7 GHz BHSs are far enough apart
Backhaul User Manual Draft for Regulatory Review
this doesn’t happen.
LAN1 IP: enter in the IP address that will be associated with the Ethernet connection on this
module. The default address is 169.254.1.1.
The radio buttons to the right of the IP address field offer the ability to make the LAN 1 IP either a
local or publicly accessible address. If the address is designated a local address it will only be
accessible via the host computer (network) that is connected to the module via the Ethernet cable.
If the address is designated a public address it will be accessible network-wide. The default for this
feature is for the address to be local. If the IP address is forgotten, the operator will need physical
access to the module and will need to create a Canopy “default plug”. See steps to create and use
a default plug in the section on the Timing Master.
LAN1 Subnet Mask: enter in an appropriate subnet mask for the module to “talk” on the network.
The default value for this parameter is 255.255.255.0
Default Gateway: enter in an appropriate gateway address for the module. The default value for
this parameter is 169.254.0.0.
Color Code: enter in a value (0-254). The color code on the subscriber module and the access
point module must match in order for registration to occur. Color code is not a security feature. It
is a means for the Canopy System operator to segregate an individual network or neighbor Canopy
networks. Also, color code can be used to force a subscriber module to only register to a specific
access point module even though the subscriber module may be able to see multiple access point
modules. The default value for this parameter is 0 on all Canopy modules.
Display-Only Password: enter the same password in both fields for verification. The display-only
password, when used, will allow only view activities to the module. When the display-only
password is set and not the full-access password, the display-only password will be tied to telnet
and FTP sessions to the module. If the full-access password is also set then it has precedence on
the telnet and FTP sessions. If the password is forgotten, the operator will need physical access to
the module and will need to create a Canopy “default plug” to override the unit. See steps to create
and use a default plug in the section on the Timing Master.
Full-Access Password: enter the same password in both fields for verification. The full-access
password, when used, will allow view and change activities to the module. When the full-access
password is set, the password will also be tied to telnet and FTP sessions to the module. When
prompted for the password via the web-based interface, there is no username required; however
when prompted for the password via a telnet or FTP session, the user that MUST be used is “root”.
If the password is forgotten, the operator will need physical access to the module and will need to
create a Canopy “default plug” to override the unit. See steps to create and use a default plug in
the section on the Timing Master.
Webpage Auto Update: enter time period (in seconds) desired to have the web browser refresh
the web-based interface. The default setting is 0, which will cause the web-based interface to
never refresh.
SM Power Up Mode with No 802.3 Link: choose which mode the module will default to when
there is no Ethernet connection sensed by the module. There are two modes available, the first is
Alignment mode and the second is Operational mode. Operational mode is the default setting.
Bridge Timeout Entry: choose the appropriate bridge timeout for correct network operation with
Backhaul User Manual Draft for Regulatory Review
existing network infrastructure. It is important that this parameter be set for a longer time period
than the ARP (address resolution protocol) cache timeout of the router being used to feed the
network.
Authorization Key: each module ships with a unique, pre-programmed authorization key to be
used when an operator configures the Canopy System for DES encryption.
Site Name: enter information relating to a name given to the physical module. This parameter will
set the supplied information into the sysName SNMP MIB-II object and can be polled by a SNMP
management server. The buffer size for this field is 256 characters.
Site Contact: enter contact information relating to the module. This parameter will set the
supplied information into the sysContact SNMP MIB-II object and can be polled by a SNMP
management server. The buffer size for this field is 256 characters.
Site Location: enter information relating to the physical location of the module. This parameter
will set the supplied information into the sysLocation SNMP MIB-II object and can be polled by a
SNMP management server. The buffer size for this field is 256 characters.
Save Changes: by clicking on this button, any changes that have been made on the Configuration
page will be committed to flash memory and will take effect after the next module reboot.
Undo Save Changes: by clicking on this button, any changes that have been made and not
committed through a reboot of the module.
Set to Factory Defaults: depressing this button will change all of the configurable parameters (all
of which are contained on the Configuration page) back to their factory settings.
Reboot: depressing this button will reboot the module.

Descriptions of the parameters that can be useful for managing and troubleshooting a Canopy
System are:
Index: each access point module that a subscriber module can see is assigned an index value for
purposes of this web page only. The index number starts with 0 and increases by 1. This index is
used to tell the operator which access point module the subscriber is currently registered to. For
Backhaul User Manual Draft for Regulatory Review
example, the first line of text on the web page says “Current entry index: 5”, the operator would
then scroll down the list of access point modules to the module with “Index: 5” to view information
about the link.
Frequency: displays the transmit frequency of the access point module.
ESN: displays the electronic serial number (MAC address) of the access point module.
Jitter: displays the last jitter value captured between the subscriber and access point module.
Range: displays the distance (in feet) between the subscriber and access point module. This
parameter will only be valid when observing the data for the access point module that the
subscriber is currently registered to.
Session Count: displays the number of times the subscriber module has gone in and out of
session with the access point. If this number is particularly large, it typically signifies that there is
some sort of issue with the link (i.e. non line of sight, interferers, etc.)
Out of Range: displays a counter for the number of times the access point module has seen a
subscriber module who has attempted to register and has been farther away than the max range
parameter on the access point.
Sector ID: displays the sector ID of the access point module.
Color Code: displays the color code of the access point module.
Sector User Count: displays the numbers of registered subscriber modules on the access point.
Rescan APs: click on this button to force the subscriber module to redo the scanning process.
The subscriber module will scan, through the frequencies checked on the Configuration web page,
for all available access point modules and register to the one that provides the best results for
RSSI, Jitter, and number of registered users.
Ethernet Stats
See the Backhaul Timing Master section. The information is exactly the same.
Expanded Stats
Clicking on the Expanded Stats link will display a number of pages of statistics that are maintained
by the Canopy module. Canopy Technical Support may ask the operator for specific information in
this section when troubleshooting an issue. There are 3 areas in the Expanded Stats that an
operator can use for managing and troubleshooting a Canopy System. Those 3 areas are:
• Link Test
• Alignment
• BER Display
Backhaul User Manual Draft for Regulatory Review
Link Test
The Link Test is a test for measuring the throughput and efficiency of the RF link between two
Canopy modules.
To perform a link test enter a number into the field labeled “Duration”. The duration is the number
of seconds the RF link will be tested. Start the link test by clicking the “Start Test” button. The test
will now run for the set duration. If the web page is not set to automatically refresh, click the
“Refresh Display” button to see the results. For a Canopy System link to be considered acceptable
it is necessary for the efficiencies of the link test to be greater than 90% in both the uplink and
downlink direction. It is recommended that when a new link is installed that a link test be executed
to ensure that the efficiencies are within recommended guidelines.
The key fields are:
• Downlink RATE, bits per second
• Uplink RATE, bits per second
• Downlink Efficiency, percent
• Uplink Efficiency, percent

Alignment
The Alignment web page contains tools to assist in the alignment of a subscriber module to an
access point module. There are two modes that can be utilized when aligning a module: 1) RSSI
only and 2) normal alignment mode.
RSSI Only is a mode where the module will report the signal strength based on the amount of
energy present at a selected frequency. The subscriber module does not have to be registered to
an access point module for information on signal strength to be reported back. This can simplify the
aiming process for long links when the Canopy passive reflector (5.7GHz band only) is being used.
To utilize RSSI only mode:
•
•
•
Choose the frequency to monitor from the pick list (this would be the same
frequency that the backhaul timing master module is transmitting on)
Click the radio button to highlight “Enable” on RSSI Only mode
Click “Enable Aiming Mode”
The module will now report back the level of RF energy present at that specific frequency. To
refresh the screen, click the Enable Aiming Mode button as appropriate or configure the web page
auto-refresh option.
The normal operation of alignment mode will report information as it relates to the RSSI level and
Jitter value. To utilize normal alignment mode, ensure that the Disabled radio button is checked
and then click Enable Aiming Mode button. As with the previous mode to refresh the mode either
continue clicking the Enable Aiming Mode button or configure the auto-refresh option. Also, during
normal alignment mode the LEDs on the outside of the Canopy module will report back information
on the performance of the link. There are 6 LEDs and when in alignment mode the LEDs are
turned into a 6-position bar graph. The more LEDs that are lit, the better the RSSI and Jitter values
the module is seeing. The colors of the LEDS have no particular meaning other than to assist is
distinguishing one position from the next.
The minimum values that are needed for an acceptable link are RSSI this above 700, Jitter that is
between 5 and 9, and link efficiencies that are greater than 90% in both the up and down link. If
any one of these criteria are not met the link may still be operational but may have issues time to
time.
Note: If a Canopy module is placed into Alignment Mode it will automatically drop into
Operational Mode after 15 minutes.
BER Display
Backhaul User Manual Draft for Regulatory Review
Bit Error Rate (BER) Display is utilized by the operator to measure the amount bit errors present in
a link. BER Display will only work if the access point module is configured to send the BER stream.
**IMPORTANT** If one access point module in a cluster is set to send a BER stream then all
other access point modules in that cluster must be configured in the same fashion.
The field, Measured Bit Error Rate, will display a value that corresponds to the BER at the moment
of web browser refresh. An acceptable link will have a BER that is less than 10-4. If the BER is
greater than 10-4 then the operator needs to evaluate the subscriber and/or access point module
installation for potential issues. To refresh the screen, click the Refresh Display button as
appropriate or configure the web page auto-refresh option.

APPENDIX
There are two basic concepts that are needed for a basic understanding of networking, IP
addresses and subnet masks. IP addresses are 32-bit binary numbers that have two
corresponding parts or sub-addresses, the first part identifying the network and the second part
identifying the hosts on the network. An imaginary boundary separates the first part from the
second. This imaginary boundary is marked by way of the subnet mask. The subnet mask is
another 32-bit binary number the acts like a filter on the IP address. When a subnet mask has a bit
set to 1, the corresponding bit in the IP address is part of the network address. A subnet is
classified as either a class A, class B, or class C network. The following table shows the common
subnet mask classes:
Class
Network Portion
Host Portion
11111111
00000000 00000000 00000000
11111111 11111111
00000000 00000000
11111111 11111111 11111111
00000000
For example, if you have an IP address of 169.254.1.1 and a subnet mask of 255.255.0.0, then the
first 16-bits of the 32-bit IP address identify the network.
10101001 11111110 00000001 00000001
11111111 11111111 00000000 00000000
IP address
Subnet Mask
There are 216 (65,536) addressable hosts in this example and 169.254 is the network. There is one
last piece of information that is needed here. Subnet masks are not shipped around in the IP
packet, the packet only contains the 32-bit IP address of the destination. So without this valuable
piece of information devices have no idea what portion of the IP address is part of the network and
which is part of the host address. How does data know where it is supposed to go? IP systems
developed a unique form of logic to make this determination. Class A network addresses always
have the first bit of their IP address set to 0. Class B network addresses always have their first bit
set to 1 and their second bit set to 0. Class C network addresses always have their first two bits
set to 1 and the third bit set to 0. By examining these first bits of the IP address a device can
determine what subnet mask should be applied to the IP address and determine where to route the
data.
The following is a synopsis of an Internet Draft (http://www.ietf.org/internet-drafts/draft-ietfzeroconf-ipv4-linklocal-05.txt) that describes how Microsoft and Apple operating systems react
when a DHCP server is not found on the network. In general, a computer needs certain
configuration information to operate on a network. Those configurations are an IP address, a
subnet mask, and possibly a gateway address. A DHCP server will automatically assign this
configuration information to a computer on a network or an operator is required to manually input
these configurable items. When a computer is brought online and a DHCP server is not accessible
(i.e. server is down or the computer is not plugged into the network) Microsoft and Apple operating
systems will default to an IP address and subnet mask of 169.254.x.x and 255.255.0.0
(169.254/16).
