GETTING STARTED WELCOME Thank you for your purchase of a Motorola Canopy Access Point cluster and/or Cluster Management 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.
OPERATION The Canopy Access Point module’s simple design allows for deployment ease. The Canopy Cluster Management Module provides everything necessary to make a system of single or multiple Canopy Access Point modules operational. It provides power, GPS synchronization and Ethernet connectivity. CONFIGURATION Access Point Module As shown below, the base cover of the module snaps off to expose the Ethernet and GPS sync connectors as well as diagnostic LEDs.
Cluster Management Module generation II There are four major assemblies contained inside the Cluster Management Module. They are the Ethernet switch, the power transformer, the interconnect board and the GPS receiver.
Earlier units had four openings on the bottom of the Cluster Management Module as shown in the following figure. Currently shipping units have two additional Ethernet cable and GPS sync cable openings, to allow use of thicker, shielded cables. N-connector to GPS antenna GPS sync cables Network feed Power feed Ethernet cables Figure 3: Bottom view of Cluster Management Module, Installed Mains AC power feed should be either 12 AWG or 14 AWG (4 mm2 or 2.
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: Access Point Module – one (1) module that is used to distribute Internet services in a 60-degree sector of up to 200 subscribers. Access Point Cluster – two (2) to six (6) Access Point modules used to distribute Internet service to a community of up to 1200 subscribers. Each Access Point module will cover a 60-degree sector for a total of up to 360 degrees.

There are 2 cables, Ethernet and GPS sync, that would connect each sector unit to the AP Installation kit.
• Lighting arrestors are required in installation area to transport lightning strikes away from 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 and absorption of the signal.
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.
Single Access Point Module A single Access Point module can use any of the frequency channels that are available. Single Access Point Cluster Use the following table as a recommendation to assign frequency channels and sector IDs (see section on Configuration interface screen for information on sector IDs). Each frequency is reused on the sector that is at a 180-degree offset. Symbol refers to the layout in the diagram below (Figure 6). 2.

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.
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.
BANDWIDTH MANAGEMENT Subscriber Module bandwidth management is set per Access Point. All Subscriber Modules which register to an Access Point module will receive and use the same bandwidth management information. The software uses “token buckets” to manage each subscriber’s bandwidth. Each subscriber’s bucket (actually two buckets, one for uplink and one for downlink) is constantly being filled with tokens at the Sustained rate, up to the Burst size (the size of their bucket).
The DAcks (Downlink ACK) Reserved High parameter describes the number of slots used to acknowledge high priority data that is received by an Access Point module. The Canopy team recommends that this parameter be set to 3 and NumDAckSlots parameter should be set to 6. The NumCtrlSlots Reserved High parameter describes the number of slots used to send control messages to an Access Point module. The Canopy team recommends that this parameter be set to 3 and the NumCtlSlots parameter should be set to 6.
Telnet +> clearwebfile Telnet+> lsweb Flash Web files free directory entries: 32 free file space 64336 bytes SNMP Simple Network Management Protocol (SNMP) can be used 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. With Canopy Release 3.2, the Canopy Enterprise MIB is available for additional information reporting and control. Consult the Release 3.
INSTALLATION The following steps are required to install the Canopy Access Point module(s), the Cluster Management Module, and the GPS antenna: • Unpack the Canopy products • Configuration of the Access Point modules • Configuration of the Cluster Management Module • Installation of the Access Point modules, Cluster Management Module, and GPS antenna • Verification UNPACK THE CANOPY PRODUCTS Upon receipt, carefully inspect all shipping boxes for signs of damage.
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. For details, see the section on the default plug under Interface Screens. - There are two types of passwords that can be configured: display-only or full-access.

The strain relief plugs on the CMM already have precut holes. Each hole of the strain relief is designed to hold two CAT 5 UTP cables, or one if it is shielded cable. - The Ethernet cables use RJ-45 connectors (standard Ethernet) that connect to matching ports within the Cluster Management Module. The ports are labeled with a “J3”.
Figure 10: Port indicator LED on Ethernet switch • • • Verify that all of the Access Point modules are reliably connected to the Ethernet switch by observing that each port indicator LED on the Ethernet switch is lit. Replace the base cover on all of the Access Point modules. Close and lock the Cluster Management Module. All Canopy modules connected to the Cluster Management Module must be configured to “Sync to Received Signal”. Otherwise GPS timing pulse will not be transmitted to the modules.
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 INTERFACE SCREENS The Canopy Access Point 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 Access Point module (default is 169.254.1.
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.
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.
CONFIGURATION Figure 13: Configuration web 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. Sync Input: choose the type of synchronization that this Access Point module will use.
cluster with other modules then this parameter on all units must be set exactly the same. The default for this parameter is 75%. High Priority Uplink Percentage: describes the percentage of the uplink bandwidth that will be dedicated to low latency traffic. When set, this percentage of RF link bandwidth will be permanently allocated to low latency traffic regardless of the amount of this kind of traffic present.
LAN 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 169.254.0.0. Private IP: the default for this parameter is 192.168.101.1. It is recommended that the operator not change this parameter.
Full Access: 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”.
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 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.
EVENT LOG This page contains information that is recorded from the subscriber module for troubleshooting purposes. Please make note of the information that is gathered here when calling for technical support. Clear Event Log: this button will clear the event log. LUID SELECT Figure 14: LUID Select web page This web page makes is possible for the operator to view the web pages of registered subscriber modules over the RF link.
LINK TEST Figure 15: Link Test web page 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.
• yyyy: four digit year Enter in the appropriate information and click the Set Time and Date button. 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.
Average RSSI: displays the average RSSI value for the subscriber module. Last RSSI: displays the last RSSI value for the subscriber module. 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 satellites seen and tracked when the Access Point module is configured to “sync to the 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.
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.
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 2.4 and 5.
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.
