Hi Thierry and Jahanzeb,

Some time ago I saw a documentation from Jahanzeb reporting the working plan
on buildind ns3 WIMAX module. The project duration, was around  8 moths (I
don't remember well). Do you thing build  the NS-3 WimAX mesh module should
take the same time, or there is somethig already built on PMP module that
can abreviate this duration?

Regards
