19 INSTALLING COMPONENTS
RECOMMENDATION:
Use shielded cable for all Canopy infrastructure connections associated
with BHs, APs, and CMMs. The environment that these modules operate
in often has significant unknown or varying RF energy. Operator
experience consistently indicates that the additional cost of shielded
cables is more than compensated by predictable operation and reduced
costs for troubleshooting and support.
19.1 PDA ACCESS TO CANOPY MODULES
For RF spectrum analysis or module aiming on a roof or tower, a personal digital
assistant (PDA) is easier to carry than, and as convenient to use as, a notebook
computer. In Release 4.2 and later releases, the PDA is more convenient to use than in
previous releases because no scrolling is required to view
◦ spectrum analysis results.
◦ received signal strength indicator (RSSI) and jitter. (See Figure 96.)
◦ AP evaluation data. (See Figure 97.)
◦ information that identifies the module, software, and firmware. (See Figure 98.)
To access this data in a format the fits a 320 x 240 pixel PDA screen, the PDA must have
all of the following:
◦ a Compact Flash card slot.
◦ any of several Compact Flash wired Ethernet cards.
◦ a wired Ethernet connection to the module.
◦ a browser directed to http://ModuleIPAddress/pda.html.
The initial page shows signal information as in Figure 96. For additional information about
the Spectrum Analyzer feature in an SM or BHS, see Monitoring the RF Environment on
Page 285.
