AP 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.
AP User Manual January 2004 Software Release 4.1 2 AP SM 4 AP 4 3 1 SM SM CMM Figure 1: Additional link to extend network sync, Design 3 • 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.
AP User Manual January 2004 Software Release 4.1 BH -M- 2 BH -S- 4 AP 4 3 1 SM SM CMM Figure 3: Additional link to extend network sync, Design 5 Wiring and configuration information for this sync extension is described under Wiring to Extend Network Sync on Page 67. 3.4 WIRING The wiring scheme of the Canopy system is displayed in Figure 4.
AP 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.
AP User Manual January 2004 Software Release 4.1 Feature Availability Canopy AES products run 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.
AP 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.
AP 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.
AP 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.
AP 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) and − the bandwidth is 64 bytes per slot, repeated 400 times each second.
AP User Manual January 2004 Software Release 4.1 3. Use a telnet session to add the new canopy.jpg file to the file system, as in the example session shown in Figure 11. NOTE: Available telnet commands execute the following results: addwebfile adds a custom logo file to the file system. clearwebfile clears the customer logo file from the file system. lsweb lists the custom logo file and display the storage space available on the file system.
AP User Manual January 2004 Software Release 4.1 4.5 DENYING ALL REMOTE ACCESS For a network where additional security is more important that ease of network administration, all remote access to an AP can be disabled as follows: Procedure 2: Denying all remote access 1. Insert the override plug into the RJ-11 GPS sync port of the AP. 2. Power up or power cycle the AP. 3. Access the web page http://169.254.1.1/lockconfig.html. 4. Click the check box. 5. Save the changes. 6. Reboot the AP. 7.
AP User Manual 4.7.1 January 2004 Software Release 4.1 Agent In SNMP, software on each managed device acts as the agent. The agent collects and stores management information in ASN.1 format, in a structure that a MIB (management information base) defines. The agent responds to commands to 4.7.2 • send information about the managed device. • modify specific data on the managed device. Managed Device In SNMP, the managed device is the network element that operates on the agent software.
AP User Manual 4.7.7 January 2004 Software Release 4.1 MIBS The MIB, the SNMP-defined data structure, is a tree of standard branches that lead to optional, non-standard positions in the data hierarchy. The MIB contains both • objects that SNMP is allowed to control (bandwidth allocation or access, for example) • objects that SNMP is allowed to monitor (packet transfer, bit rate, and error data, for example). The path to each object in the MIB is unique to the object.
AP User Manual January 2004 Software Release 4.1 Objects An object in the MIB can have either only a single instance or multiple instances, as follows: 4.7.8 • a scalar object has only a single instance. A reference to this instance is designated by .0, following the object identifier. • a tabular object has multiple instances that are related to each other. Tables in the MIB associate these instances. References to these instances typically are designated by .1, .
AP User Manual January 2004 Software Release 4.1 Procedure 4: Installing the Canopy Enterprise MIB files To use this MIB, perform the following steps: 1. On the NMS, immediately beneath the root directory, create directory mibviewer. 2. Immediately beneath the mibviewer directory, create directory canopymibs. 3. Download the following three standard MIB files from http://www.simpleweb.org/ietf/mibs into the mibviewer/canopymibs directory on the NMS: • SNMPv2-SMI.
AP User Manual January 2004 Software Release 4.1 • Accessing Subnet, which specifies the subnet mask allows managers to poll the agents. • Trap Address, which specifies the IP address of the NMS. For more information about each of these fields, see the user document that supports the module. 4.7.

AP 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 SPECIFIC MOUNTING CONSIDERATIONS The Canopy APs must be mounted • with hardware that the wind and ambient vibrations cannot flex or move. • where a tower or rooftop is available or can be erected.
AP User Manual January 2004 Software Release 4.1 5.2 GENERAL RF CONSIDERATIONS The network planner must account for the following general characteristics of RF transmission and reception. 5.2.1 Vertical Beam Width The transmitted beam in the vertical dimension covers more area beyond the beam center. The Canopy System Calculator page BeamwidthRadiiCalcPage.xls automatically calculates the radii of the beam coverage area. Figure 12 displays an image of this file.
AP User Manual 5.2.2 January 2004 Software Release 4.1 Radio Horizon Because the surface of the earth is curved, higher module elevations are required for greater link distances. This effect can be critical to link connectivity in link spans that are greater than 8 miles (12 km). The Canopy System Calculator page AntennaElevationCalcPage.xls automatically calculates the minimum antenna elevation for these cases, presuming no landscape elevation difference from one end of the link to the other.
AP User Manual 5.2.3 January 2004 Software Release 4.1 Antenna Downward Tilt The appropriate angle of antenna downward tilt is derived from both the distance between transmitter and receiver and the difference in their elevations. The Canopy System Calculator page DowntiltCalcPage.xls automatically calculates this angle. Figure 14 displays an image of this file.
AP User Manual January 2004 Software Release 4.1 An unobstructed line of sight is important, but is not the only determinant of adequate placement. Even where the path has a clear line of sight, obstructions such as terrain, vegetation, metal roofs, or cars may penetrate the Fresnel zone and cause signal loss. Figure 15 illustrates an ideal Fresnel zone. Fresnel zone receiver transmitter Transmitter or Amplifier Figure 15: Fresnel zone The Canopy System Calculator page FresnelZoneCalcPage.

AP User Manual January 2004 Software Release 4.1 This functionality can be used during the alignment of an SM, but is especially helpful for frequency selection during site planning. The following procedure causes the SM to drop any active RF link. If a link is dropped when the spectrum analysis begins, the link can be re-established after a 15-minute interval has elapsed. Procedure 6: Enabling spectrum analysis The Spectrum Analyzer in SM and BHS feature provides this functionality.
AP User Manual January 2004 Software Release 4.1 7. Access the Link Test page of the module. 8. Assess whether the desired links for this module achieve • uplink efficiency greater than 90%. • downlink efficiency greater than 90%. 9. If the desired links fail to achieve any of the above measurement thresholds, then a. access the module by direct Ethernet connection. b. access the Configuration page of the module. c. in the Power Control parameter, click Full. d. click Save Changes. 5.5.4 2.
AP User Manual January 2004 Software Release 4.1 Where spectrum analysis identifies risk of interference for any of these channels, the planner can compromise this recommendation as follows: • Select 2.4375 GHz for the middle channel • Select 2.455 GHz for the top channel • Select 2.4175 GHz for the bottom channel In any case, the plan should allow at least 20 MHz of separation between channels. See Spectrum Analysis on Page 50. 5.5.5 5.2-GHz AP Channels Channel selections for the AP in the 5.
AP User Manual 5.5.6 January 2004 Software Release 4.1 5.7-GHz AP Channels Channel selections for the AP in the 5.7-GHz band depend on whether the AP is deployed in cluster. 5.7-GHz Single AP Available U-NII Channels A single 5.7-GHz AP can operate in the following U-NII channels, which are separated by 5-MHz increments as advised in the caution above. (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.
AP 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.

AP User Manual 5.5.8 January 2004 Software Release 4.1 Multiple Access Points Clusters When deploying multiple AP clusters in a dense area, consider aligning the clusters as shown in Figure 22. However, this is only a recommendation. An installation may dictate a different pattern of channel assignments.
AP 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).
AP 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.
AP User Manual January 2004 Software Release 4.1 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: 6.3.1 • IP address of 169.254.1.1 • Subnet mask of 255.255.0.0 • Network gateway of 169.254.0.0 Operator Assignment of IP Addresses The Canopy network operator assigns IP (Internet Protocol) addresses to computers and network components, by either static or dynamic IP addressing.
AP User Manual January 2004 Software Release 4.1 7 AP MODULE INSTALLATION The following steps are required to install a Canopy AP: 1. Unpacking the Canopy Products. See Page 61. 2. Cabling the AP. See Page 62. 3. Configuring the AP. See Page 67. 4. Installing the AP and, optionally, the CMM and GPS (Global Positioning System) antenna. See Installing the AP on Page 70. 5.
