We have a couple locks on campus that use 802.15.4. I think it is a Stanley product. I was told by the engineer who was trying to sell us on the product campus wide, that it would cause no interference. (haha!) I can confirm co-channel interference, but no user reported problems wifi problems that i could specifically say were caused by that equipment. So that statement was inaccurate, as I knew it would be, but only in a boastful way. It also took a couple of visits an i want to say a couple of months to get it to work. (I don't remember exactly) I have expressed to our access staff that I do not like the deployment, and if I was the deciding vote, I would say no to a proposal to deploy more like it.
I was initially skeptical of the ASSA ABBLOY locks we have on campus, but they have been great. For a purely network standpoint they are my choice. Our access staff likes them as well. The only problem I have had is that my older wireless plans didn't really plan for coverage of outside doors. In one or two places that has been an issue we have had to overcome, but that wasn't the lockset's fault. *TLDR:* I would be uneasy about 802.15.4 locks. Your access folks should get competing quotes for locks that use 802.11g/n over your existing infrastructure. If you do decide on an 802.11g/n based product, check for adequate coverage.
