Patent ID: 7203515

Claim:
A wireless local loop system for interfacing with one or more analog communication devices, the wireless local loop system comprising: a MODEM for converting between analog and digital data, the MODEM comprising: a data modem for at least (1) converting the analog signal provided by the one or more analog communication devices via a SLIC (SLT interface Circuit) into a class ‘0’ digital data, or (2) converting a class ‘0’ digital data provided by a mobile station modem (MSM) into an analog signal, and providing the analog signal to the SLIC; a memory for temporarily storing data wherein the data comprises at least (1) the class ‘0’ digital data converted by the data modem, or (2) the class ‘0’ digital data provided by the MSM; a controller in communication with the MSM and the SLIC for at least (1) converting the data to be in conformity with protocol characteristics of the one or more analog communication devices, (2) controlling signal processing at the data modem, and (3) reading/writing data from/to memory; the MSM providing an interface between an antenna and the MODEM; and the SLIC providing an interface between one or more analog communication devices and the MODEM, wherein the SLIC matches analog data line characteristics of at least a telephone or that of the one or more analog communication devices, wherein the MODEM operates to at least (1) receive an analog data signal provided by the one or more analog communication devices via the SLIC, convert the analog data signal into a class ‘0’ digital data, and provide the class ‘0’ digital data to the MSM, or (2) receive a class ‘0’ digital data provided by the MSM, convert the class ‘0’ digital data into an analog data signal, and provide the analog data signal to the analog communication device through the SLIC, and wherein the MSM operates to at least (1) code digital data provided by the MODEM, convert the coded digital data into a digital baseband signal, and provide the digital baseband signal to an antenna, or (2) decode a digital baseband signal received through the antenna to produce information data, and provide the information data to the MODEM.
