RF Media Access
The client wireless driver will connect with the WallPlate that has the strongest RSSI. Regardless
of which WallPlate is selected by the client driver, the co-channel interference will be one other
WallPlate, very low co-channel interference and well within the bandwidth of the RF medium.
Redundancy
Five total WallPlates are within -70dBm of the client. Thus, if one WallPlate fails, the client will
always maintain a high datarate connection to the network.

Using the same installation density, let’s look at the resulting RSSI loss when the loss per
wall/room combination is 15dBm and the floor loss is 5dB greater than the horizontal.
Note that WallPlates A, G, C, and I are all approximately -95dBm, right at the edge of the carrier
detect range of -94dBm. Additionally, WPs two floors up will also appear within the carrier detect
range.
