1. A communication system comprising:
optical components configured to generate an optical signal having a first data stream modulated onto a first optical mode of the optical signal and having a second data stream modulated onto a second optical mode of the optical signal, the second optical mode being orthogonal to the first optical mode;
a light source configured to add an optical local oscillator (LO) signal to the optical signal;
a first antenna radiating element;
a first photodiode coupled to the first antenna radiating element, the first photodiode being configured to transmit first wireless signals over the first antenna radiating element based on the optical LO signal and the first optical mode of the optical signal;
a second antenna radiating element; and
a second photodiode coupled to the second antenna radiating element, the second photodiode being configured to transmit second wireless signals over the second antenna radiating element based on the optical LO signal and the second optical mode of the optical signal.
