Abstract

A method and system for sharing components in a time division multiplex wireless system is provided. The method may include configuring at least one component of a software programmable radio, such as a PLL, to enable communication of data using, for example, a GSM protocol during a first timeslot in a frame and reconfiguring that component to enable communication of data using a different communication protocol during an unused timeslot in the same frame. Both uplink and downlink channels of the different communication protocol may be communicated during the unused timeslots.
