Not Homogenous
There are zones
with very different
traffic values
Offer Completion Methodology
The completion of a Radio offer must follow the following stages:
Stage 1: Collection of Customer Requirements
Same as the previous case except for the fact
that the traffic value used as hypothesis
must not be increased.
Divide into zones and treat each zone as
the case of a Full DECT site with running
costs optimization
1. Phase 1: Determine the customer’s objectives
This initial phase is usually conducted by the commercial manager.
• Objectives:
• Determine the customer's requirements per zone
• Determine the site complexity
• Retrieve the plans/drawings
• Retrieve the information relative to the traffic and user distribution
• Results:
• Classification of the project and associated risks
• Completion of the costs hypotheses dossier
2. Phase 2: Analysis of the site
This second phase can be completed by the commercial manager, offer technical support
or radio measurements manager, preferably on site.
• Objectives:
• Confirm the project complexity
• Complete the information retrieved in phase 1 (plans/drawings, traffic, distribution)
• Retrieve information relative to the site
• Results:
• Confirm classification of the project and associated risks
• Quantify the measurements services to be carried out
• Propose an initial approach for base station numbers by integrating the traffic and
coverage data and their positions
This phase is preferable to activate phase 3 in good conditions for the sizing of the
resources needed by the service and to provide an initial strategy recommendation to
follow as regards the measurements to be carried out.
3. Phase 3: Radio coverage study
In all cases, real life radio measurements are recommended to confirm the positioning and
quantity of the base stations (field, fading level and quality level measurements using a
portable tester equipped with 4074 and Alcatel Mobile Reflexes 200 mobile testers).
They are essential in the zones classified as tricky coverage.
• Objectives:
