I'm looking at implementing the reduce cell size option for a high-density VoWLAN implemenation. I haven't seen it as a suggestion until the Lync VRD was released, and believe that a benefit can be seen by implementing it. I've done a lot of research regarding it and have compared it to Cisco's implemenation. Aruba's implemenation appears to be different in that you reduce the cell sensitivity in dB (floor noise - reduce size size = receive sensitivity) which means it is dynamic, whereas Cisco you set the sensitivity to a static value in dBm (ex: -75dBm). It seems to me that the receive sensitivity on Aruba APs could change depending on the floor noise, going down/up as floor noise changes, which is a bit concerning. I've seen APs randomly dip in floor noise as much as 10dB, so it's possible that when those dips occur, the AP may stop hearing clients because the receive sensitivity is much lower than it was before. Any thoughts on this?
