Abstract: Systems for wireless communication may select a photonic signal to generate a carrier frequency for wireless communication. In an illustrative example, the selected photonic signal may have sidebands with a frequency difference corresponding to a carrier frequency within one of multiple predetermined carrier frequency bands. In some implementations, each of the predetermined carrier frequency bands may contain a local minimum signal attenuation characteristic over a signal path of the wireless communication. For example, the selection of the photonic signal may be based on predetermined selection criteria such as error information, and/or signal path conditions (e.g., atmospheric humidity level, noise, signal strength). Apparatus for performing such methods may include a wireless communication system with a transmitter and/or receiver.
