Cisco had their access points only ten feet from each other and sent all of the data from a single point.

It means that through extrapolation of the power curves of a wireless network the percentage above -30dB is 5.47% of the area with respect to a full power range.

When the robots are in close proximity, they will overwhelm the signals from the much more distant stations they are communicating with. The traffic would have to be extremely low for this to be workable.
Yes there is a drop in throughput but the robots only need 19.2 Kbps. Wireless can run up to 11Mbps. This means there can be almost a 99% drop and the robots would still work fine.
