Abstract:
1. A base unit for distributing extremely high frequency (EHF) modulated data signals to at least one remote antenna unit (RAU), comprising: a downlink data source input configured to receive a downlink electrical data signal from a data source; an electrical-to-optical (E-O) converter configured to convert the downlink electrical data signal into a downlink optical data signal; an oscillator configured to generate an electrical carrier signal at a center frequency in an EHF band; a modulator configured to combine the downlink optical data signal with the electrical carrier signal to form a downlink modulated optical signal comprising the downlink optical data signal modulated at the center frequency of the electrical carrier signal, the modulator further configured to send the downlink modulated optical signal to at least one RAU; and an uplink receiver comprising at least one antenna, the uplink receiver configured to operate at a frequency substantially lower than EHF to receive uplink electromagnetic signals from at least one wireless client through the at least one antenna.
