We have 2.4GHz 802.15 locks installed alongside Wi-Fi in quite a few buildings. They fit pretty nicely between 802.11 channels, and duty cycle is so low that interference isn't worth worrying about.
This isn't my area, but I'll share it in case it prevents somebody from learning this the hard way. Frequent connections to check for updates can wear down the batteries in the locks very quickly. One building was configured to connect every 15 minutes and the batteries were dead in three months. Now we set them up to check twice a day most of the year, and res hall locks are reconfigured to check every 15 minutes during move-in weeks only. Batteries are replaced once a year.

I know wireless locks are going to happen here, but perhaps I can convince planners to compromise with an 802.15-based system. I'm not sure which 802.15 specification you are referring to, but 802.15.4 operates in 2.4 GHz or 868/915 MHz. This particular Assa Abloy PR100 lock product uses 802.15.4 at 2.4 GHz (by far the most prevalent frequency for 802.15.4 deployments): http://www.sargentlock.com/products/product_overview.php?item_id=2106 802.15.4 channels are 2 MHz, and can be deployed between 802.11 channels 1/6/11 at 2.4 GHz with some success. This is a good read on 802.11 2.4 GHz and 802.15.4 2.4 GHz coexistence. http://www.jennic.com/download_file.php?file=JN-AN-1079+Coexistence+of+IEE E+802.15.4+In+The+2.4GHz+Band-1v0.pdf -Josh ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
