Both cables should have the same length. The first interface of the system’s UAI16 board

should not be used since the operator station uses those points.

4.8.1.2 NUMBER OF USEFUL BASE STATIONS

Any radio signal is subject to various propagation phenomena: attenuation, reflection and

diffraction. These phenomena are related to the environment of the Alcatel-Lucent 4070

IO/EO, and affect the radio performance of the system.

The effects can improve or deteriorate wave propagation.

Take as an example a building with a metallic structure. A radio wave will tend to be subject to

many reflections which will consequently degrade system performance.

Moreover, the range of an Alcatel-Lucent 4070 IO/EO is very dependent on the amount of

attenuation subjected to the radio wave across various zones.

The following table gives the values of global coverage zone (cell) for an Alcatel-Lucent 4070

IO/EO under normal environmental and topological conditions:

Interior Exterior

Coverage area ~ 50 m ~ 400 m

Area: ~ 7,000 m

~ 50 000 m
