John, Testing by Alvarion engineers has been done. Saying that a radio has an aggregate throughput of 14 meg's for voip is not really applicable. Small packets through the radio can bring most systems to their knees. Brad

Whether you would like to realize it or not, canopy has come a ways over the years. If you consult with your engineers I'm sure you'll conclude that a Canopy AP/SU(14Mbps aggregate) could do a LOT more than 10 calls... Jon Langeler Michwave Tech.
