-Transmitted Mbps (TxMbps) is calculated with the formula (TxMbps = rate * EWMA) where rate is the 802.11 data rate in use by the transmitter and EWMA is the Exponetially Weighted Moving Average or the current time weighted chance that a packet at this rate will reach the remote station.  If no traffic is being routed to the Neighbor, this value may be '0' until data is available to measure and determine the optimal settings.
