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 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 Lever Ethernet Cable FIGURE 1 Remove the base cover as shown in FIGURE 1 to access the Ethernet connection and the Connection LED alignment indicators.
The diagnostic LEDs report information about the current status of the access point module. following descriptions explain the function of each LED. The Operational Mode 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.
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.
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.
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. 5.2 GHz Recommended Frequencies The following are the 3 non-overlapping channels that are recommended by the Canopy team for use with the backhaul module: • 5.275 GHz • 5.300 GHz • 5.
NETWORKING INFORMATION The Canopy access point module will each utilize 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 Canopy backhaul system can create a point-to-point links within the following distances: Configuration Distance Both ends of the link using the internal patch antennas 2 miles (3.2 km) One end of the link using a Canopy passive reflector 10 miles (16 km) Both ends of the link using Canopy passive reflectors 35 miles (56 km) 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.
ADVANCED FEATURES These features may be used in the Canopy System but are not required for basic operation. DES ENCRYPTION DES (Data Encryption Standard) is a secret key encryption scheme. The basics of DES are that it performs a series of bit permutations, substitutions, and recombination operations on blocks of data utilizing a secret key.
Telnet +> clearwebfile Telnet+> lsweb Flash Web files free directory entries: 32 free file space 64336 bytes SNMP Simple Network Management Protocol (SNMP) can be utilized to monitor the Canopy modules. The standard MIB-II (systems and interfaces) objects are programmed into the modules. For 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 backahaul 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 transporatation 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: “ , . ‘ { } / \ ; : [ ] ( ) ` ~ 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: 1. Lock down timing master module 2.
CABLING The following information describes the wiring standards for installing a Canopy system. All diagrams use the EIA/TIA 568B color standard. Currently shipping modules 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. Earlier modules did not auto-sense.

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.
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.
