Frequency band adaptive wireless communication
View Patent ↗A system, apparatus and method is disclosed for multiband wireless communication. Frequency bands and/or transmission formats are identified as available within a range for wireless communication. The system evaluates signal quality metrics for each frequency band and selects a communication method based on the evaluation. Multiple frequency bands and communication methods can be utilized by the system such that a combination of licensed, unlicensed, semilicensed, and overlapped frequency bands can be simultaneously used for communication. The system monitors communications and can report link performance for adaptive control of the selected communication methods.
