Patent ID: 11949462
Assignee: APPLE INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 4:
5. The communication system of claim 2, wherein the optical signal generator is configured to generate an additional optical LO signal that is offset in frequency from the optical LO signal by a frequency gap, further comprising:
an additional antenna radiating element;
an additional photodiode coupled to the additional antenna radiating element; and
an additional optical path configured to illuminate the additional photodiode with the additional optical LO signal and an additional carrier from the set of evenly spaced carriers, the additional carrier being separated in frequency from the carrier by the frequency gap and the additional photodiode being configured to generate, based on the additional optical LO signal, the additional carrier, and a bias voltage applied to the additional photodiode, an additional current on the additional antenna radiating element, the additional current on the additional antenna radiating element being configured to radiate additional wireless signals that include at least some of the wireless data.
