Which chip is best?

Hi,

I am a WiFi engineer (software), we have two more generations of
product that use different wifi chips. I want to have somebody to
discuss and compare various wifi chips so we can make a better choice
in our next product.

We have experience with Philips BGW200, which is not so good in our
product, it seems works not so good in complex environment(eg, with
more than 20 AP around), and the compatibility is not so good.

And we also used the TI's wifi solution(known as wilink), it is better
than BGW200 I think, and it's SDK expose more API to manipulate the
detailed radio frame.

I don't know the price( who knows?), and otherbody has experience with
better product?

Thanks.
Bin
