Abstract :
There is considerable interest in broadening the use of PCS (1.9 GHz) spectrum and the cellular (850 MHz) spectrum beyond the primary applications that drove the development of the technologies being deployed. Providing a single wireless terminal that a person can use outdoors in a traditional cellular mode, and indoors in homes and offices in a cordless telephone mode or wireless PBX mode may be an attractive way to broaden wireless usage and applications. A challenge for the single wireless terminal concept is to provide quality for indoor systems that is equivalent to wireline. Design alternatives for an advanced mode of operation for IS-136 TDMA that supports voice access with wireline quality (at about 16 kbps) while maintaining 3 voice circuits per carrier are proposed By wireline quality, we mean the ability to support tandems, voice-mail and music-on-hold with excellent quality
