The introduction of Third Generation mobile phones will offer vastly increased data capacity ensuring the proliferation of mobile Internet use and new multimedia uses.To ensure that global roaming would be possible for third generation mobile phones the World Radiocommunications Conference (WRC) in 1992 defined the operating frequencies for UMTS to be 1885 MHz to 2025 MHz (uplink) and 2110 MHz to 2200 MHz (downlink). Uplink is defined as information passing from the subscriber to the base station while downlink is information passing from the base station to the subscriber. Figure 1 shows UMTS frequency allocation. The upper band of these frequencies is reserved for future Mobile Satellite Service (MSS).
