Described is an arrangement including a controlling arrangement, a
wireless transceiver and a processor. The wireless transceiver
communicates with a wireless device utilizing radio frequency signals at
a transmitting power level. The processor collects network performance
data ("NPD") which is indicative of communication with the wireless
device. The NPD includes at least one characteristic of the signals. The
controlling arrangement adjusts the transmitting power level for the
transmission of further radio frequency signals as a function of the NPD
and previously collected NPD.
