    , and 915 MHz but can be programmed in steps of 250 Hz for operation at other frequencies in the UHF range. The chip operates as a conventional heterodyne receiver. The RF input is converted to an intermediate frequency, then gets filtered and fed to a frequency shift-key demodulator. Demodulated data

"The orthogonal frequency division multiplexing (OFDM) used in 5-GHz networks happens to be relatively immune to impulse noise," says Kraemer. "If a wideband
