Abstract:
1. A wireless local loop (WLL) apparatus for communicating with a base station, the apparatus comprising: a WLL cellular terminal comprising: a modem for coding or decoding a signal communicated over a cellular communication network; a universal serial bus (USB) device connected to the modem for communicating with an external device; a first communication port to receive data from the external device; a USB line driver connected to the USB device to process the information received through the first communication port; and a first power connector for receiving power from an external power source; and a detachable charger comprising: wherein the WLL cellular terminal communicates directly with the base station over a wireless local loop cellular communication network, wherein the wireless local loop cellular communication network comprises a cellular telephony network that supports communication between the wireless local loop cellular base station and the WLL cellular terminal in a local area, without providing a hand-off feature such that the WLL cellular terminal is unable to connect to the wireless local loop cellular communication network when the WLL terminal travels beyond the local designated area covered by the wireless local loop cellular base station, wherein the wireless local loop cellular base station is remotely connected to the WLL cellular terminal in a wide area wireless cellular network, so that a line connecting the base station to a PSTN line need not terminate at a local area where the WLL cellular terminal is utilized, and wherein the wireless local loop cellular base station is further remotely connected to a plurality of other WLL cellular terminals in the wide area wireless cellular network such that said plurality of WLL cellular terminals are not utilized within the local area where the WLL cellular terminal is utilized.
