How do these proprietary protocols differ from 802.11's PCF? I read the whitepaper that was referenced, and it is lacking in details (and accuracy). >This polling software(which you could also emulate to certain extent with >low RTS treshold) is a fake solution.

I'm not sure how a low RTSThreshold will emulate polling, since that only increases the number of packets sent using the RTS/CTS CA protocol, nor do I agree that polling is a "fake" solution -- it is used quite effectively in a number of systems. Perhaps you could expand on this. -Gavin |
