Abstract:
1. An apparatus for routing messages in wireless networks, comprising: a first plurality of filters, each of said plurality of filters adapted to provide a plurality of frequency-based message signals converted from an optically-based signal; a plurality of mixers connected to the first plurality of filters, the mixers adapted to mix the plurality of frequency-based message signals with a plurality of sub-carriers to generate a plurality of frequency-based sub-carrier modulated message signals; a frequency generator connected to the plurality of mixers for providing the plurality of sub-carriers to the mixers; a combiner connected to the mixers for combining the plurality of frequency-based sub-carrier modulated message signals; a second plurality of filters connected to the combiner and adapted to receive and group the plurality of frequency-based sub-carrier modulated message signals; a plurality of optical transmitters, each of said plurality of transmitters connected to one of the second plurality of filters for optically converting and transmitting the frequency-based sub-carrier modulated message signals.
