CHAPTER 4
Radio Coverage Verification
4.1 General
The radio coverage verification consists of two tests:
z Base Station test
z Area coverage test
Ensure that the Base Stations are properly installed. Please take the following into account:
z Mounting
z Wiring
z Initialization (CSMW Software)
The Base Station should always be mounted such that the antennas are vertical with respect to
the floor or ceiling. Two types of antennas are available to facilitate the correct orientation of the
Base Station. One set is a vertical antenna for wall mounting of the Base Station and the other set
is a right angle antenna that allows the Base Station to be mounted on the ceiling.
The Base Station should never be mounted above the ceiling tiles as this reduces the coverage
area. Base Stations should not be mounted near large metal objects, such as pipes or air
conditioning conduits. Do not mount Base Stations directly on I-Beams or lamp poles, as these
objects tend to distort the RF field which reduces the effectiveness of the RF coverage area. Use
the Base Station outdoor wall mounting kit (see Section 5, Installation Instructions, Chapter 16,
Base Station – KRC 101 1371, Paragraph 16.7) or a factory hanging device (see Section 5,
Installation Instructions, Chapter 16, Base Station – KRC 101 1371, Paragraph 16.6.3). Do not
mount the Base Station more than 20 ft. high.
Note:
When mounting base stations nearby each other to provide additional call capacity, it is necessary
to maintain at least 40 inches spacing between base stations.
The location where the Base Station is to be mounted is determined either by a previous site
survey or by the needs of the customer when adding to a system.
The following is a recommended order of installing a Base Station:
- Base Station cable delay measurement
- Mounting the Base Station - indoor
- Mounting the Base Station - outdoor
- Connecting the Base Station plug to the cable
4.2 Base Station Test
The purpose of this test is to check if all Base Stations are operational.
Test
1. Put a Portable Telephone in the DCA mode (refer to Section 7, "Maintenance" in this manual).
2. Take the floor plan of the area where the Base Stations are indicated with their corresponding
Base Station number or use the Base Station identification and location sheet in Section 5,
"Installation Instructions" in this manual.
