Dear Experts,
I'm new to WiMAX, please pardon my layman question.
I'm wondering whether there is any possibility to put the current
intel chip into base station mode, like we can do on some WiFi chips?
For example, I remember I setup a Wifi testbed a while back using a
handful of Athroes chip + madwifi.
While it might be *possible*, it would certainly require different
firmware that hasn't to my knowledge been supported or released by
Intel. I don't believe that Intel is interested in the base station
business at the moment, so I doubt they would ever release base
station
firmware to the general public. Given that WiMAX is usually used in
regulated spectrum, you'd have to have a license from your regulator
agency to do this anyway, or risk the wrath of the incumbent owners of
the spectrum you'd be broadcasting on :)

I was thinking to use 5.8-GHz band to setup a testbed in our Lab, and
I was told that it's license-exempt in Canada. The reason I like to
have the testbed is to experiment with some cross-layer optimizations
in WiMAX, which may require me to change the MAC layer. However, it's
extremely hard to find a base station that would allow me to do that.
(and that's probably why most papers evaluate their algorithms using
simulations).
The only two possible ways I have come across are: (i) the femto base
station reference design from Fujitsu. But per their sales team, the
project had been cancelled and the chips never went into production.
(ii) the intel chip. But, I have to agree with you that Intel is
unlikely to release a new firmware for base station.
So, I guess I'm stuck.
Please kindly let me know if there are other possibilities for me to
exercise the algorithms in the base station.
Finally, I apologize that this is a bit OT.
Thanks,
Chenghsin
