The links Julius and I provided will take you to the standard
documents that describe the air interface.

Thanks julius and Eric. 

Let me explain a bit more, what I am looking for are the specs on the
modulator and pulse shaping filter for the two standards. Are there specs
describing the modulation and pulse shaping requirement? Like in WCDMA,
3GPP TS 25.101 describe the pulse shaping filter and 3GPP TS 25.213
describe the modulator? If anyone can point me directly to the specs, it is
greatly appreciated.

Or here: http://standards.ieee.org/getieee802/portfolio.html BT is 802.15. The waveforms aren't even close to compatible, so the general means of sensing each other for avoidance is just energy detection. Since the ISM band is unlicensed energy detection is more general, anyway, since an interferer may be a cordless phone or any other device compliant to the ISM rules.

I don't know what BT is but for 802.11 standards, you can either read about it on good ole wikipedia or read the actual standards. If you don't know yet, they are available for free. http://en.wikipedia.org/wiki/802.11 http://ieee802.org/11/

Hi all,

I am working on the coexistence study between BT and WLAN. Anyone knows
where are the spec on modulation and pulse shaping for BT and 802.11 a, b,
g WLAN?
