.1 (an extract from Table 2.1) illustrate this increase. Table 6.1 Range of Transmission Rates High level Maximal bit rate Maximal speed Cell coverage description (kbits/s) (km/h) Rural outdoor Macrocell Suburban outdoor Microcell Macrocell Indoor/ Picocell Low range outdoor Microcell Then the question of the transmission range for UTMS services, is no longer just what transmission rates, but what type of services, when and where. It is no longer "commu- nications any where any time", but "what I want when I want where ever I want". Practically, the exploitation of wider transmission rates will facilitate the expansion of data traffic. As illustrated Table 6.2 there exists a clear trend for the convergence of IP protocol to wireless, or to what we now call wireless IP. The latter will lead to the Wire- less Internet, where about 200 M Internet and 300 M mobile subscribers will merge into 1 billion Wireless Internet users. Table 6.2 Convergence of Internet Protocol (IP) to Wireless Computer: mobility Telecommunications: mobility Media: mobility high speed services wide services personal services Internet access ISDN services Streaming audio Electronic mail Video telephony Video on demand Real time images Wideband data services Interactive video services Multimedia Location services coupled with TV/radio/data contribution application servers and distribution Non-voice services will make demands not only on manufacturers and operators but also from supporting industries, creating a need for new service enablers. However, The UMTS Network and Radio Access Technology such demand will also introduce new challenges and the need for pragmatic integration of services and devices, as well as new data processing and managing techniques. These demands can be summarized as needs as illustrated in Table 6.3.
