Typically, installations such as office buildings, hotels and hospitals should be equipped with both base
stations and repeaters on several floors to create uniform and complete radio coverage.
Open areas can be covered with a sparse network of base stations. In such deployments, the base stations
and/or repeaters cover an extended range due to the extended line-of-sight radio propagation capability
The figure below shows an example of an installation where base stations are not spaced at the right
distances:
4.4.2 Capacity Planning
This is where the Network provider estimates how many calls will be initiated in a typical window/time
frame and how many users will be initiating them.
Another aspect of capacity planning should address the user growth pattern of a typical SME VoIP network.
How many users will be using this network in for example two years window, etc. Based on these
estimations, the network dimensioning can be planned orderly bearing in mind the SME capacity.
The capacity of the SME VoIP System is summarised as follows (this should guide the network planner):
