Hi all, Off-topic, but I received an odd error when sending this last e-mail to the listserv. Did anyone else receive this notice shown in this screenshot? It appears that this is probably just an issue with some security setting in our Office 365 tenant, but I was just curious. Apologies for the off-topic message.

Learn about spoofing<http://aka.ms/LearnAboutSpoofing> Feedback<http://aka.ms/SafetyTipsFeedback> Hi all, I hope I’m not late in replying to this e-mail thread. We had a number of Assa Abloy wifi locks in one of our residence halls. The wireless coverage in that building was not up to snuff to cover those locks, unfortunately. As we could not upgrade wireless in that location and more and more issues popped up with those locks, we eventually pulled them out in favor of wired locks that were replaced by the vendor. This doesn’t totally address the question here, but our locks would have been perfectly fine and required nearly no attention had WAPs been deployed properly up front. Best wishes!

I am not directly involved, but my understanding is the wireless locks are less than ideal. Two primary issues are that the units we use have a limited character string, so we had to create a process to truncate the IDs before uploading to the lock. Also, these have a limited amount of IDs they can hold and don't purge records when the database is updated. Inactive IDs are only disabled so a manual purge of each individual lock at least once a year.

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.

These comments are related to Wi-Fi vs Wireless: Advantages: 1. Cheaper installation (due to being able to use the existing Wi-Fi network instead of installing access control specific infrastructure). 2. Lower probability of interference – but note that the locks transmit very little data (and the Wi-Fi ones generally only come on periodically, often only once a day). Disadvantages: 1. The locks are offline most of the time (they come online on a periodic basis). That means that updates are slower (as the locks only update periodically), so you can’t do lock-downs with them, lost card updates don’t take effect right away, etc. 2. It’s harder to diagnose certain types of lock problems (since it’s offline most of the time, you don’t see updates right away, and checking whether the lock is online or offline doesn’t matter since it’s offline most of the time). 3. Battery life is often worse (especially if you turn up the update frequency to deal with the other problems). Wi-Fi locks can be great for locks that don’t need updates very often and where you don’t need lockdown functionality. I would personally recommend going with wireless over wi-fi whenever possible, but there are times Wi-Fi is absolutely more practical. If you have specific questions on the above feel free to ask (I manage the electronic access control locks at Otis College as well as the Wi-Fi network).

Hi Greg, Locks tend to have a very low network duty-cycle, so interference between the 802.15.4 network and 2.4GHz Wi-Fi will be minimal. That said, it may be worth considering Wi-Fi locks instead. That will ensure that they play well with other Wi-Fi devices and will spare the institution the cost of installing and managing a separate network for locks. On the down side of using Wi-Fi locks, the refresh cycle for Wi-Fi is shorter than for locks. If you have a bunch of locks reliant on outdated features it could hamper Wi-Fi performance down the road. The refresh cycle would have to be discussed with your facilities management, and/or security people. To the group, can you think of any other advantages/disadvantages of putting the locks on Wi-Fi?

I'm a bit concerned that there will be some impact to our 2.4Ghz clients (we have a ton of them out there still). Anyone else out there have these or something similar and can speak for how they work and if there are any issues in your environment? --greg Gregory A.
