Yes, there are plenty of people out there who still prefer this method, or have customers who demand it. One thing that has become apparent is that a number of people are still using power sources (generally a battery pack) for their survey AP that still only supports the 802.3af POE (power over Ethernet) standard.

The next generation of wireless access points simply won’t allow the continued use of 802.3af power packs, due to the enhanced power requirements of modern APs. Background Until relatively recently, many Enterprise grade wireless access points have been able to work with the
