12.4.2 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.
12.5 Network Dimensioning
After the network requirements are clearly defined, the number of users that are expected to use the
network must be estimated. Based on that, you should estimate and identify the number and type of
equipment required in order to cater for the capacity, coverage and quality requirements. The more
accurate the dimensioning, the more efficient the network rollout.
Handsets/SIP End-Nodes:
In a typical setup, the system can support up to 1000 handsets depending on the configuration.
Base stations/Repeaters:
The system can easily scale up to 50 base stations. Depending on the network setup, coverage can be
extended by up to 3 repeaters pr. base station. The planner should bear in mind that base stations can
support 10 simultaneously call sessions while repeaters can support 5 call sessions.
