The evaluation toward next-generation wireless networking brought life to the concept of technology and services integration. The success attained by the Internet, on one side, and by cell phone networks, on the other, led to visions of "Next-generation networks," integrating the two different philosophies. On one hand, Internet Protocol (IP) technology has been developed in order to support a new range and variety of services, previously only possible with circuit switching technologies, due to the very low cost of Internet access. On the other hand, cellular telephony technology also boomed during this Internet evolution, bringing commodities now very keen to humans: mobility and reachability.
