OFDM receiver and methods for operating in high-throughput and increased range modes

A receiver to operate in accordance with one of the IEEE 802.11 standards comprising:

• fast Fourier transform (FFT) circuitry to generate frequency domain symbol-modulated subcarriers for a set of orthogonal frequency division multiplexed (OFDM) subcarriers,
• wherein during an increased-range mode, data is to be received on a single subchannel and the FFT circuitry is to generate frequency domain symbol-modulated subcarriers for a set of OFDM subcarriers associated with the single subchannel, and
• wherein during a high-throughput mode, data is to be received on each subchannel of a plurality of subchannels and the FFT circuitry is configured to generate frequency domain symbol-modulated subcarriers for a different one of the subchannels.

A method for receiving OFDM symbols comprising:

• receiving OFDM symbols on a single subchannel and generating frequency domain symbol-modulated subcarriers for a set of OFDM subcarriers associated with the single subchannel when an increased-range mode is enabled;
• and
• receiving OFDM symbols on each subchannel of a plurality of subchannels and generating frequency domain symbol-modulated subcarriers for a different one of the subchannels when a high-throughput mode is enabled.
