Chapitre 3 - Deployment principles
3.1 Description
Before beginning deployment procedures ensure that the following studies have been
conducted:
• Radio coverage for the entire site.
It must be possible to send and receive calls within the coverage area.
• Site traffic study.
The number of simultaneous calls must be determined according to the number of users and
their habits.
The operations to be performed can be organised into 5 distinct steps:
Note: It is highly recommended to respect the order of these steps during deployment.
Following this order will provide increased efficiency, speed and reliability of the work
performed.
1 Interview with the customer
In this step, gather all the information necessary to determine the coverage areas, and the
traffic for each area.
2 Determining and segmenting the radio coverage area
The overall coverage area must be determined and divided into areas. The number and size
of the areas will depend on the required coverage area, the dimensions, and physical
constraints of the customer’s site.
3 Determining the number of base stations
For each area, indicate the number of base stations necessary to support the level of traffic
required.
4 Grouping the areas
Depending on the traffic requirements, group the areas into cells managed by the PBX.
5 Customer review and documentation
Come to an agreement with the customer and/or owner of the premises, concerning the
number of base stations and their location and any modifications to be made to the premises
(additional jacks, relocation of metal cabinets, etc.).
