The MSC 280 is configured to interface with a public switched telephone network (PSTN) 290. The MSC 280 is also configured to interface with a BSC 275 that can be coupled to the base station 270 via a backhaul line. The backhaul line can be constructed in accordance with any of a number of well known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. It will be understood that the system as shown in Figure 7 can include multiple BSCs 275.

Each BS 270 can serve one or more partitions (or regions), each of which is covered by a multi-directional antenna or an antenna directed to a particular direction radially away from the BS 270. Alternatively, each partition may be covered by two or more antennas configured to receive diversity. Each BS 270 can be configured to support multiple frequency allocations, and each frequency allocation has a particular frequency spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of partitioning and frequency allocation can be referred to as a CDMA channel. BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be configured to generally mean a single BSC 275 and at least one BS 270. The base station can also be Called "cell station." Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cellular stations.
