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.
Module Description The base cover of your Canopy Backhaul is easily removed by depressing the release lever on the back of the cover. Base Cover Base Cover Release Ethernet Lever Cable FIGURE 1 Remove the base cover as shown in FIGURE 1 to access the Ethernet connection and the Connection LED alignment indicators. ♦ The RJ-45 connector is used to attach the Ethernet cable ♦ The RJ-11 connector is used to attach the GPS sync cable ♦ The LED’s indicate system status and are used for alignment.
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.
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.
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.
CMM Canopy Backhaul Master Canopy Backhaul Slaves CMM Canopy Backhaul Master Example 3: The multiple hop with the backhaul master modules in the middle of the link. Canopy Backhaul Slave CMM Canopy Backhaul Masters Canopy Backhaul Slave 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.
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.
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.
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.
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.
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.
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.
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.
specific information on this MIB see RFC 1213 for details.
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.

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
• 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.
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.

Site Name: enter information relating to a name given to the physical module.
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.
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.
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.
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.
ACCESSORIES The following accessories are available for use with the Canopy System. To purchase accessories, please contact an authorized Canopy dealer, unless otherwise noted. • Universal mounting bracket • Passive reflector dishes for use with 5.7 GHz subscriber modules. • 90-220V AC power supply (part number ACPSSW-01) Cable assemblies for the Canopy System can be ordered from Best-Tronics Manufacturing Inc. by going to their website at http://www.best-tronics.com/motorola.
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.
