发明名称 HIGH DENSITY WIRELESS SYSTEM
摘要 A method and apparatus for communicating within a wireless microphone system having a plurality of audio channels. The method includes the steps of dividing a small block of radio frequency spectrum associated with a single television broadcast channel into a plurality of at least 20 contiguous subchannels that are also contiguous with the boundaries of the television broadcast channel where each of the subchannels is less than 75 kHz and transmitting an audio signal from a microphone transmitter on one the plurality of subchannels through a transmitter with a radio frequency isolator or other means for suppressing intermodulation energy coupled to an antenna, the radio frequency isolator having a bandwidth no larger than any one of the plurality of divided subchannels; and receiving the audio signal through a microphone receiver.
