Note that there two different types of locks that don’t require individual 
cabling, usually referred to wireless or wi-fi.

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  If you have a bunch of locks reliant on outdated features it 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?

Chuck

It’s not what you’re asking, but we are using ASSA-ABLOY .11n locks. Fairly 
easy to support.

Haven't seen any recent discussion here about wireless door locks.  Our 
physical access team is looking to install some wireless door locks in an 
administrative building.  I can see it growing past this building pretty 
rapidly and want to make sure they aren't putting in something that is going to 
cause us headaches.

They are looking to install Aperio "HUB's" as they call them:

This appears to be using some variant of 802.15.4, which has the ability to run 
between our 802.11g/n 2.4Ghz channels, but will cause co-channel interference.  
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?
