GETTING STARTED WELCOME Thank you for your purchase of a Motorola Canopy Backhaul module. This new technology is the latest innovation in high speed wireless networking. Some of the Canopy system features are: - Network speeds of 10/100 BaseT - Small compact design - No special set up on your PC. INTENDED USE This manual is intended to be used with Canopy software release version 3.x or greater. The intended audience for this manual is system operators and equipment installers.
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 both the 5.2 and 5.7 bands and in both 10 and 20 Mbps. 5.7 backhauls can be used with reflectors on either or both ends. 5.2 backhauls cannot be used with reflectors in the US or Canada due to regulatory agency restrictions. The following table shows typical ranges for each type of backhaul.

Canopy BH RJ11 Connector RJ45 Connector Connection LEDs Base Cover Ethernet Cable FIGURE 2 The diagnostic LEDs report information about the current status of the access point module.
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.
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.

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 5.2 GHz or 5.7 GHz modules, frequencies should never be placed closer than 20 MHz. The Canopy modules allow the operator to chose frequencies every 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 5.2 GHz band or within the 5.
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.
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: “ , .
• 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: 1. Lock down timing master module 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.

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.
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 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.
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.
