SM User Manual January 2004 Software Release 4.1 3.3 SYNCHRONIZATION The CMM is a critical element in the operation of the Canopy system. At one AP cluster site or throughout an entire wireless system, the CMM provides a GPS timing pulse to each module, synchronizing the network transmission cycles. 3.3.1 Unsynchronized Modules Without this pulse, an AP is unsynchronized, and a BH timing master cannot synchronize a BH timing slave.
SM User Manual • January 2004 Software Release 4.1 Design 4 1. A CMM provides sync in Ethernet protocol to a collocated AP. 2. This AP sends the sync in multipoint protocol over the air to an SM. 3. This SM delivers the sync in Ethernet protocol to a collocated BH timing master. 4. This BH timing master passes the sync in point-to-point protocol in the additional link over the air to a BH timing slave. This design is illustrated in Figure 2.
SM User Manual January 2004 Software Release 4.1 Wiring and configuration information for this sync extension is described under Wiring to Extend Network Sync on Page 74. 3.4 WIRING The wiring scheme of the Canopy system is displayed in Figure 4. AP units GPS sync & Ethernet cables from each unit* GPS antenna GPS antenna cable network connection in optional backhaul module 300SS CMM2 AC or DC power in grounding system * Two cables, Ethernet and GPS sync, connect each sector AP to the CMM2.
SM User Manual January 2004 Software Release 4.1 4 ADVANCED FEATURES The following features are available in the Canopy system but not required for basic operation. 4.1 SECURITY FEATURES Canopy systems employ the following forms of encryption for security of the wireless link: 4.1.1 • BRAID–a security scheme that the cellular industry uses to authenticate wireless devices. • DES–Data Encryption Standard, an over-the-air link option that uses secret 56-bit keys and 8 parity bits.
SM User Manual January 2004 Software Release 4.1 Feature Availability Canopy AES products operate on the same software as DES products. Thus feature availability and functionality are and will continue to be the same, regardless of whether AES encryption is enabled. All interface screens are identical. However, when encryption is enabled on the Configuration screen • the AES product provides AES encryption. • the DES product provides DES encryption.
SM User Manual 4.2.2 January 2004 Software Release 4.1 Recharging Buckets The Burst Allocation variable field in the AP sets the size of each bucket. This limits the maximum number of tokens that can fill a bucket. If the SM transfers data at the Sustained Data Rate, then the bucket refills at the same rate, and burst is impossible. If the SM transfers data at a rate less than the Sustained Data Rate, then the bucket continues to fill with unused tokens.
SM User Manual January 2004 Software Release 4.1 Input Rate 128 Kbps Sustained Rate 128 Kbps Burst Allocation 128 Kb Effective Rate 128 Kbps with no Burst Figure 6: Burst Allocation vs. Sustained Rate, Example 2 Input Rate 128 Kbps Sustained Rate 128 Kbps Burst Allocation 56 Kb Effective Rate 56 Kbps with no Burst Figure 7: Burst Allocation vs. Sustained Rate, Example 3 Input Rate 128 Kbps Sustained Rate 128 Kbps Burst Allocation 0 Kb Effective Rate 0 Kbps Figure 8: Burst Allocation vs.
SM User Manual January 2004 Software Release 4.1 The high-priority channel is enabled by configuration of four parameters in the Configuration web page. These parameters are: 4.3.1 • High Priority Uplink Percentage • UAcks Reserved High • DAcks Reserved High • NumCtrlSlots Reserved High High Priority Uplink Percentage The High Priority Uplink Percentage parameter defines the percentage of the uplink bandwidth to dedicate to low-latency traffic.
SM User Manual January 2004 Software Release 4.1 Example Allocation At AP default downlink-to-uplink settings (75% downlink and 25% uplink), if High Priority is set to 25%, then • in the uplink, the total of reserved slots is equivalent to 25%, 2 slots in this example: − The bandwidth is 64 bytes per slot, repeated 400 times each second. − [2 slots/instance] x [64 bytes/slot] x [8 bits/byte] x [400 instances/second] = 409,600 bps ≈ 400 kbps of uplink bandwidth • 4.3.

To assist end users in this area, the Canopy division offers a starter guide for one of these viewers—MRTG (Multi Router Traffic Grapher).
SM User Manual 4.8.1 January 2004 Software Release 4.1 NAT NAT isolates the SMs from the Internet. This both enhances SM security and obviates the need for a special assignment scheme of IP addresses that identify the SMs. Where NAT is active, the SM serves as a Layer 3 switch. (By contrast, where NAT is not active, the SM serves as a Layer 2 bridge.
SM User Manual January 2004 Software Release 4.1 This implementation is provisioned as displayed in Figure 38: IP Configuration screen, NAT disabled on Page 92 and Figure 44: NAT Configuration screen, NAT disabled on Page 99. 4.8.4 NAT with DHCP Client and DHCP Server The NAT with DHCP Client and DHCP Server implementation is illustrated in Figure 13.

SM User Manual January 2004 Software Release 4.1 5 SITE PLANNING The following considerations are critical in the choice of a location for the wireless network infrastructure. Note: Since each site is unique, typically many additional considerations are critical. 5.1 SELECTION OF SM TYPES AND PASSIVE REFLECTORS A system plan may include • SMs that are not mounted to Passive Reflectors, operate in the 5.2-GHz band, and communicate with an AP in the 5.2-GHz band.
SM User Manual 5.2.1 January 2004 Software Release 4.1 Lightning Protection The network plan must include lightning protection. The following precautions are strongly recommended: 5.2.2 • Install a lightning protection system for the site. • Observe all local and national codes that apply to grounding for lightning protection. • Use a Canopy Surge Suppressor to protect equipment from surges on the Ethernet cable that is connected to the Canopy System.

SM User Manual January 2004 Software Release 4.1 5.4 CANOPY COMPONENT PROLIFERATION The network planner must account for the coordination of both initial and future Canopy modules. 5.4.1 Subscriber Modules The planner must always consider the distribution of SMs as relative to the distribution of APs and clusters. The planner must also consider that the SMs and the AP to which they register should operate on the same software release. See AP Update of SM Software Release on Page 56. 5.4.
SM User Manual January 2004 Software Release 4.1 Procedure 5: Auto-updating SMs To upgrade SMs to a later release, the operator performs the following steps: 1. FTP the file SMboot.bin, FPGA, and the action list to AP, as shown in Figure 24. < ls 062403_D40.jbc APASboot.bin BH10boot.bin SMboot.bin 41actionlist.txt APboot.bin BH20boot.bin > ftp 172.16.1.1 Connected to 172.16.1.1. 220 FTP server ready Name (172.16.1.1:user): 331 Guest login ok Password: 230 Guest login ok, access restrictions apply.

SM User Manual January 2004 Software Release 4.1 A BH and an AP on the same tower, or separated by less than 100 feet (30 meters), require a CMM. The CMM properly synchronizes all Canopy modules to prevent interference and desensing of the modules. NOTE: Cross-band deployment of APs and BH is the recommended alternative (for example, a 5.2-GHz AP collocated with 5.7-GHz BH). 5.6.2 Spectrum Analysis In Release 4.1 and later releases, the operator can • use an SM as a spectrum analyzer.
SM User Manual January 2004 Software Release 4.1 Procedure 7: Invoking the low power mode The Power Control feature provides this functionality. To enable this functionality, the operator performs the following steps: 1. Access the Configuration page of the module. 2. In the Power Control parameter, click Low. 3. Click Save Changes. 4. Click Reboot. 5. Access the Alignment page of the SM. 6. Assess whether the desired links for this module achieve • RSSI greater than 700.
SM User Manual January 2004 Software Release 4.1 2.4-GHz AP Cluster Recommended Channels Three non-overlapping channels are recommended for use in a 2.4-GHz AP cluster: (All Frequencies in GHz) 2.4150 2.4350 2.4575 This recommendation allows 20 MHz of separation between one pair of channels and 22.5 MHz between the other pair. The network planner can use the Spectrum Analysis feature in an SM or BHS, or use a standalone spectrum analyzer, to evaluate the RF environment.
SM User Manual 5.6.6 January 2004 Software Release 4.1 5.7-GHz Channels Channel selections for the AP in the 5.7-GHz band depend on whether the AP is deployed in cluster. Channel selections for the BH are not similarly limited. 5.7-GHz BH and Single AP Available U-NII Channels A BH or a single 5.7-GHz AP can operate in the following U-NII channels, which are separated by 5-MHz. (All Frequencies in GHz) 5.745 5.765 5.785 5.750 5.770 5.790 5.755 5.775 5.795 5.760 5.780 5.800 5.
SM User Manual January 2004 Software Release 4.1 The channels of adjacent APs should be separated by at least 20 MHz. However, 25 MHz of separation is advised. 5.7-GHz AP Cluster Recommended ISM/U-NII Channels Six non-overlapping ISM/U-NII channels are recommended for use in a 5.7-GHz AP cluster: (All Frequencies in GHz) 5.735 5.775 5.815 5.755 5.795 5.835 The fully populated cluster requires only three channels, each reused by the module that is mounted 180° offset.

SM User Manual January 2004 Software Release 4.1 6 IP NETWORK PLANNING A proper IP addressing method is critical to the operation and security of a Canopy network. The following information provides the background for the planner or operator to select an appropriate method. 6.1 GENERAL IP ADDRESSING CONCEPTS Basic concepts of IP addressing and subnet masks are required for networking. 6.1.1 IP Address The IP address is a 32-bit binary number that has four parts (octets).
SM User Manual January 2004 Software Release 4.1 Identification of Subnet Class Subnet masks are not shipped in the IP packet. The packet contains only the 32-bit IP address of the destination. For this reason, information devices rely on assumption to distinguish between • the portion of the IP address that identifies the network address • the portion of the IP address that identifies the host.
SM User Manual January 2004 Software Release 4.1 6.3 SM MODULE ADDRESS ASSIGNMENT Each SM requires an IP address on the network. This IP address is for only management purposes. For security, the SM should be either • not assigned a routable IP address. • assigned a routable IP address only if a firewall is present to protect the SM. From the factory, each Canopy module—AP, BH, or SM—is assigned a unique MAC (Media Access Control) address and the following default networking information: 6.3.
SM User Manual January 2004 Software Release 4.1 7 SM MODULE INSTALLATION The following steps are required to install a Canopy SM: 1. Unpacking the Canopy Products. See Page 69. 2. Cabling the SM. See Page 70. 3. Configuring the SM. See Page 75. 4. Installing the SM. See Page 77. 5. Verifying System Performance. See Page 80. 7.1 UNPACKING THE CANOPY PRODUCTS Upon receipt, carefully inspect all shipping boxes for signs of damage. If you find damage, immediately notify the transporatation company.
SM User Manual 7.1.2 January 2004 Software Release 4.1 Diagnostic LEDs The diagnostic LEDs report the following information about the current status of the SM, as described in Table 11 for the timing slave. NOTE: Table 11 identifies the LEDs in order of their left-to-right position as the cable connections face downward. Table 11: SM status LEDs Notes Label Color when Active Status if Registered to an AP LNK/5 green Ethernet link Continuously lit when link is present.
SM User Manual January 2004 Software Release 4.1 Table 12 identifies by MAC address whether a module auto-senses the Ethernet cable type. Table 12: Module auto-sensing per MAC address Module Type MAC Address (ESN) of Non Auto-sensing Module MAC Address (ESN) of Auto-sensing Module 2.4-GHz modules (no ESNs) (all ESNs) 5.2 Modules ≤ 0a003e0021c8 ≥ 0a003e0021c9 5.
