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.
5.4.2 Access Point Modules
The number of APs deployed can vary from site to site, based on the locations of SMs that these
modules must reach. The mounting scheme can also vary from site to site. The APs need not be
mounted adjacent to each other. For example, on a three-legged tower, two APs can be mounted
to each tower leg.
5.4.3 Access Point Clusters
Each AP cluster requires a CMM for seamless operation within the entire Canopy system. Thus the
network planner should consider the number and locations of CMMs that will be deployed as the
Canopy network grows.
5.4.4 Backhaul Modules
The network planner should consider where BHs will be required
• to connect the Canopy system to the outer network.
• to span distances with a wireless link (see Types of SM Applications on Page 16).
• to generate and deliver network sync to a site (see Synchronization on Page 18).
• to pass network sync in one additional link to a remote site (see Synchronization on
Page 18).
The network planner should also consider the frequency band of each BH that will be deployed
• to avoid self-interference (see Physical Proximity on Page 58).
• to use the extended range that the Canopy Passive Reflector dish provides (see Types
of SM Applications on Page 16 and Selection of SM Types and Passive Reflectors on
Page 47).
5.5 AP UPDATE OF SM SOFTWARE RELEASE
In Release 4.1 and later releases, the operator can upgrade to a later release any SM that
operates on Release 4.0 or later. To do so, the operator uses the FTP (File Transfer Protocol) and
telnet utilities. The interval required for each SM update is approximately four minutes.
