摘要：
Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for transmission may vary with time. Once a group of OFDM sub-channels is selected, a power level and modulation technique may also be selected based on channel quality.
