Fig. 3.15: Example of location areas
Distributing radio units among several location areas only makes sense as of a cer-
tain system size. The radio units are allocated by means of configuration. For a
description of the best way to group the radio units of a system in location areas,
see page 631 ff.
5.3 System characteristics
5.3.1 Radio characteristic of a radio unit
The coverage range of a radio unit depends among other things on the antenna
through which the radio signal is transmitted. The SB-4 and SB-8 radio units trans-
mit through two integrated antennas inside the housing. The radio characteristic
of internal antennas is virtually spherical (with only transmission to the rear slightly
diminished), in other words registered handsets are able to move away from the
radio unit the same distance in every direction without the radio signal breaking
up. This does not take account of the topology that attenuates the signal’s prop-
agation.
