CONVERTING A WIRELESS SYSTEM DEPLOYMENT FROM ONE DUPLEXING SCHEME TO ANOTHER

摘要

A method includes, in a wireless network including radios operating in aFrequency Division Duplexing (FDD) mode in wireless subscriber stations andwireless basestations, freeing a portion of spectrum to enable deployment of radiosoperating in a TimeDivision Duplexing (TDD) mode, replacing a first portion of FDD radios in thewirelesssubscriber stations and wireless base stations with H-FDD radios to avoidinterferencebetween FDD radios and TDD radios, utilizing a guard band frequency of thespectrumbetween the FDD radios and the TDD radios for operation of the H-FDD radios,andreplacing FDD radios in a remaining portion of the wireless network with TDDradios.
