8.10.1.2 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:

8.10.1.4 Locating DECT base stations
As a result of the environment and the infrastructure, certain recommendations must be taken into
account for locating Alcatel-Lucent 4070 IO/EO:
