Wireless Signal In an Elevator
I recently installed a wireless network camera in an elevator. The signal is, for the most part, decent, but we are still experiencing some issues with getting a consistent signal, especially on the bottom floors of the building. We have several access points located outside of each elevator door on the various floors.
Has anyone encountered an installation like this? How can I improve the signal?

Answer Wiki:
The main issue with this is that the elevator shaft will block a lot of the signal. If you can get a maintenance man to get you into the shaft itself you could mount an access point in the shaft. Depending on how many floors you have it could be strong enough to bounce the signal all the way to the bottom. Easiest way to test this is to take the one from the top floor, open the door and hang it in the shaft when the elevator is at the bottom. Or if there is a maintenance door at the top where the motor cables go through that would be better. Once it is in the shaft it will have a clear path all the way down with no wall interference.

As the possibilties and benefits of VoIP become more notable in this companie’s situation, increasing wireless access for wireless handsets is becoming increasingly more important.
I have investigated mounting a point at the top of the shaft and the bottom respectively (8 very tall floors to span) but I am starting to lean against mounting on the ceiling. The motor room is directly above the cieling, and this creates a lot of RF interferance. I have also been considering mounting points on the side of the shaft, as there are windows with sills.
Thanks for your input.
