Assignee: APPLE INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 9:
10. A method of operating a communication system comprising:
generating, using an optical signal generator, a first optical local oscillator (LO) signal and a set of evenly spaced optical carriers that are offset from the first optical LO signal;
modulating, using an optical modulator, wireless data onto the set of evenly spaced optically carriers to produce a set of evenly spaced modulated optical carriers;
conveying, using an optical fiber, the first optical LO signal and the set of evenly spaced modulated optical carriers to an optical demultiplexer;
demultiplexing, using the optical demultiplexer, the set of evenly spaced modulated optical carriers and providing the first optical LO signal and a first modulated optical carrier from the set of evenly spaced modulated optical carriers to a first photodiode; and
transmitting, using the first photodiode, first wireless signals at a first frequency over a first antenna radiating element using the first optical LO signal and the first modulated optical carrier.
