Hi All
Ranjeet as rightly put forth by fayqa naqshbandi these are open source tools. And since she has already designed the optical part in optisystem so all she needs is to design the wireless part in such a tool so that it can be in some or the other way with her optical part of the project in optisystem. thus she has only limited choices and among those according to me simulink or matlab would be a favourable option.

Burhan
