b. If you cannot establish a connection with a given radio, see
"Troubleshooting a Base Station."
5. Verify call hand-off and radio coverage by walking through the
entire coverage area (including stairs and elevators, if
applicable) while on a call. Another method to do this is to
measure the RSSI (see your COMPANION 200 Portable
Telephone Registration Instructions) and walk from cell to cell
while observing the radio number and RSSI indications on the
portable display. (The RSSI value should remain at or above the
cell boundary value defined in the COMPANION Deployment
Tool User Guide).
If a significant hole in the coverage area is found, first ensure that
all the Base Stations in that area are working properly. If they
are, this confirms that a gap in the coverage exists. Refer to the
COMPANION 200 Site Planning Guide to re-deploy Base
Stations to fill the gap, or add an additional cell if necessary.
6. Establish a connection with a radio and measure the RSSI level
(see your COMPANION 200 Portable Telephone Registration
Instructions). Repeat for each portable from the same location.
Replace any portable whose reading is significantly different
(about 10 dB or more) from that of the others.
Note: For better results, choose a location close to a cell
boundary and always connect to the same Base Station
(disable the other radios at that cell center).
Note: The lower the RSSI value, the weaker the signal strength.
A display of - 44 is the strongest (best) possible signal
strength.
