  • Page 9: Product Description, Canopy Backhaul, Module Description

    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.

    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.

  • Page 12: Background Information On Networking

    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.

  • Page 13

    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.

  • Page 14: Site Selection Criteria

    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.

  • Page 15

    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.

  • Page 16: General Considerations

    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.

  • Page 17: Channel Plans, Ghz Recommended Frequencies

    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.

  • Page 18: Networking Information, Lightning Protection, Electrical Requirements

    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.

    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. Stainless steel hose clamps Reflector dish arm...

  • Page 20: Advanced Features, Security - Des Encryption, Security - Aes Encryption

    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.

    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 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.

  • Page 25: Alignment

    • 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.

  • Page 26: Cabling

    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.

  • Page 28: The Interface Screens

    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.

  • Page 29: The Timing Master, Quick Start

    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.
