—Software suitable for estimating Mobile WiMAX
capacity in network planning and optimization is presented.
The implementation of the software is based on analytical
method to evaluate IEEE 802.16e Mobile WiMAX system’s
capacity, throughput and a traffic model for mixed application
users. Various Overheads that impact the capacity of the system
are analyzed. A step by step description of the analysis is made
and a flow chart for the determination of available bandwidth
and maximum number of users supported is presented. Based
on the description of the flow chart, a program in java language
that implemented the entire analysis is written. A simulation of
the software is used for the determination of the maximum
number of subscribers that each specific Mobile WiMAX sector
can support. This would help service providers to plan and
implement a wide coverage network in a city. The proposed
analytical method and software program will enable service
providers to estimate the number of base stations that can be
deployed in a given area. Thus the network investment,
profitability and avoidance of future network congestion can be
evaluated and estimated.
