Claim:
1. A method comprising: receiving, by a station, energy related to communication signals by a normal rate preamble detector and by a low rate preamble detector in parallel; determining, by a channel traffic logic of the station, traffic indicator values for a communications channel, the traffic indicator values comprising a channel occupancy value being indicative of an amount of traffic on the communications channel over a period of time, a duty cycle being indicative of a time that the station is in an active state, and a buffer size being indicative of an amount of data to be transmitted/received; disabling, by the station, the low rate preamble detector based upon the traffic indicator values, wherein disabling the low rate preamble detector is in response to determining that the traffic indicator values are below a threshold channel traffic value related to determining a balance between saving power and utilizing the low rate preamble detector; and enabling, by the station, the low rate preamble detector based upon the traffic indicator values, wherein enabling the low rate preamble detector is in response to determining that the traffic indicator values are above the threshold channel traffic value.
