109 Verifying the installationCOMPANION 200 Installation and Maintenance Guide P0725810 Issue 3.0b. 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 theentire coverage area (including stairs and elevators, ifapplicable) while on a call. Another method to do this is tomeasure the RSSI (see your COMPANION 200 PortableTelephone Registration Instructions) and walk from cell to cellwhile observing the radio number and RSSI indications on theportable display. (The RSSI value should remain at or above thecell boundary value defined in the COMPANION DeploymentTool User Guide).If a significant hole in the coverage area is found, first ensure thatall the Base Stations in that area are working properly. If theyare, this confirms that a gap in the coverage exists. Refer to theCOMPANION 200 Site Planning Guide to re-deploy BaseStations 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 RegistrationInstructions). 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 cellboundary 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 signalstrength.Verifying a radio’s cell assignmentTo verify a radio’s cell assignment, follow these steps:1.
