Dual mode radio for frequency division duplexing and time division duplexing communication modes. In some embodiments, dual mode radio for frequency division duplexing and time division duplexing communication modes includes a multi-mode communication unit for wireless communication, in which the multi-mode communication unit allocates access for a time based communication mode and a frequency based communication mode; and a processor configured to implement at least in part the multi-mode communication unit. In some embodiments, the time based communication mode includes a time division duplexing (TDD) communication mode, and the frequency based communication mode includes a frequency division duplexing (FDD) communication mode.
