Abstract

A radio using non-simultaneous frequency diversity includes: an antenna (502), a radio frequency module (504) coupled to the antenna (502) such that the radio frequency module (504) is operable to transmit (556) or receive (554) radio frequency signals using the antenna, and a baseband module (506) coupled to the radio frequency module. The baseband module is operable to transmit or receive signals through the radio frequency module, such that signals transmitted or received by the radio employ non-simultaneous frequency diversity. A method for transmitting information using non-simultaneous frequency diversity includes: identifying information to be transmitted, transmitting the identified information on a first channel, and after a predetermined amount of time, transmitting the identified information on a second channel. A method for receiving information transmitted using non-simultaneous frequency diversity includes receiving a first signal transmitted on a first channel; after a predetermined amount of time, receiving a second signal transmitted on a second channel; and identifying transmitted information based on the first signal and the second signal.
