Abstract:
A method includes determining a first aggregate received power level of an orthogonal frequency division multiplexed (OFDM) signal received at a first network node, adjusting a nominal PHY Margin an amount that is dependent upon a measurement of an aggregate received power level of the OFDM signal, determining a data transmission rate based on the adjusted nominal PHY Margin, and receiving data being transmitted in accordance with the data transmission rate at the first node.
