If the CCA detects 802.11, then I suppose it would backoff from that. I'm not sure it will detect 802.11 though. If I understand it correctly, CCA will try to receive 8 802.15.4 symbols and if it can, then call that someone transmitting. I suspect that 802.11 co-existence is supposed to be "handled" via channel selection (ED scan) and route formation using LQI. > Just curious on what you've found on typical implementations. What I've typically found in most implementations is that they ignore as much of the 802.15.4 spec as they can get away with. -Mar. ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 _______________________________________________ Linux-zigbee-devel mailing list Linux-zigbee-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-zigbee-devel
