A method includes, in a wireless network including radios operating in a Frequency Division Duplexing (FDD) mode in wireless subscriber stations and wireless base stations, freeing a portion of spectrum to enable deployment of radios operating in a Time Division Duplexing (TDD) mode, replacing a first portion of FDD radios in the wireless subscriber stations and wireless base stations with H-FDD radios to avoid interference between FDD radios and TDD radios, utilizing a guard band frequency of the spectrum between the FDD radios and the TDD radios for operation of the H-FDD radios, and replacing FDD radios in a remaining portion of the wireless network with TDD radios.
