I currently have several AP's scattered throughout a large warehouse which completely floods the area with a wireless signal. Although I can't give you the exact signal strength, I can say that the signal never drops below 3 out of 4 bars on my mobile. My problem currently exists when I am currently on a call with someone either using 3cx for android or 3cx phone for windows. Call quality will be great during the start of the call, but will have call quality issues when moving around the building. It will get to the point where the call has no audio whatsoever for a short while, but then the call resumes a second or two later with no call quality problems. I am thinking that this is an issue with the wireless device 'holding' onto one AP until the point where the two devices cannot communicate then quickly connects with another. Is there a way of moving from one AP to another without having to completely lose a connection first?
