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.
System Wiring Diagram AP units GPS sync & Ethernet cables from each unit* GPS antenna GPS antenna cable optional backhaul module Network Connection in Cluster Management AP Installation Kit Module 300SS AC or DC power in grounding system * Cables from only 1 sector are shown in diagram. There are 2 cables, Ethernet and GPS sync, that would connect each sector unit to the AP Installation kit.
• There must be grounding systems available for protection of the Canopy equipment. • 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.
CHANNEL PLANS Whether using Hz 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 an Access Point cluster: • 5.275 GHz • 5.300 GHz • 5.
5.7 GHz Plan Direction of Access Point sector Frequency Sector ID Symbol North – (0°) 5.745 GHz 0 A Northeast – (60°) 5.765 GHz 1 B Southeast – (120°) 5.785 GHz 2 C South – (180°) 5.745 GHz 3 A Southwest – (240°) 5.765 GHz 4 B Northwest – (300°) 5.785 GHz 5 C Multiple Access Points Clusters When deploying multiple Access Point cluster in a given area it is recommended that the clusters be aligned in the following manner.
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 DES (Data Encryption Standard) is a secret key encryption scheme. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data using a secret key. On the base Canopy system, DES encryption of the over the air link is turned on per Access Point module or Backhaul timing master module.
Low Latency bit. If this bit is set, the packet will be sent on the high priority pipe. This pipe is serviced before any normal priority traffic. The high priority system is enabled via four fields found in the Configuration web page. The fields are: • High Priority Uplink Percentage • Uacks Reserved High • Dacks Reserved High • NumCtrlSlots Reserved High The High Priority Uplink Percentage parameter describes the percentage of the uplink bandwidth that will be dedicated to low latency traffic.

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.
• The operator must configure the appropriate color code on the Access Point module so that subscriber modules can register with it. The color codes must match for registration. • The operator must configure the maximum range that the Access Point module will register a subscriber module. If the Access Point module is in a cluster with other modules then this parameter on all units must be set exactly the same.
Fuse receptacle AC power connectors 115/230 V switch Figure 7: Location of 115/230 V Switch • • The AC power connectors are labeled - N for Neutral - L for Line - PE for Protective Earth (PE) (ground) The maximum thickness wire to be used is 12 AWG (4 mm2).
- • The modules can be mounted in a variety of locations, choose the best location for your particular application. Modules do not have to mounted directly next to each other, they can be distributed throughout a given site. Mounting can be done by using stainless steel hose clamps or another equivalent fastener. Mount the Cluster Management Module - Mount the module in a location that will allow access for service if necessary.
Figure 9: Detail of GPS antenna mounting • • Route the Ethernet cables from the Access Point modules to the Cluster Management Module. 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 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.

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.
• • Synchronization Network IP Address 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.
Registered SM Count: displays the number of subscriber modules currently registered to the Access Point module. 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.
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.
• • dd: yyyy: two digit day 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.
compared to other subscriber modules registered with this Access Point, there may be an issue with the installation of the subscriber. 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.
RxOverrun: displays the total number of receiver-overrun errors on the Ethernet controller. 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.
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) for Access Point modules • 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.
