Need help on WiMAX base station design

[musfiq]

i need some information on designing WiMAX base
controller software. what is the best place to start ?
is it analyzing the standard or something else.
any guidelines will be highly appreciated.

fyi: we will use open source linux 2.6.18 kernel
version. we have expertise on linux kernel and its networking
details. i know that the new 802.16e MAC layer is much
more robust and needs a lot of optimization on netstack,
specifically on L2 and L3. we are also planning to buy wimax
bs chips from some renowned manufacturer. we have the
information that the at least the lower MAC and PHY layer
will be present on the chip.

what we have lack is that we don't have any experience
on designing base stations before. please help.

You are in deep trouble. I hope you aren't alone and you're working into a team configured with at least one RF engieer, one PCB desigh aritecture engineer, and one or more software engineers...

Start with reading the 2004 wimax standard and the 2006 wimax standard covering the mobile stations because the BS will talk with many MS. Then hack all informations about similar products on the market. Choose the RF front end chips and the baseband solution. The keywords will be EVM and frequency range (licensed or non-licensed band?). Chose the configuration: FDD or TDD ? Choose the PA solution and the switching solutions. Implement the software and test&test&test

A good team will need about one year (ok a half year if they are genius and have a ready made design) for a working implementation of a Wimax BS and at least two or three real hardware+software revisions.

success,
