Trends & technical challenges in conversational voice services

Technologies continuously evolve to meet the challenging needs of wireless communication. The ever growing demand for wireless communication requires greater capacity and higher network efficiencies. Spectral efficiency is a key driver of the economics of voice and data services as we approach the rollout of 3G network. In this paper we discuss the technology trends and challenges associated with conversational voice services in the context of fixed mobile conversion. We discuss evolution in cellular modem technology, switching technology, and speech coding technology. The combination of voice over internet protocol and wireless communication promises to revolutionize the whole telecommunication market.
