Abstract
The system utilizes host signal processing techniques applicable to cellular communication system devices which are integrated with a system incorporating a general purpose CPU running a multitasking operating system. A RF receiver processes the signals to generate a receive signal, the RF module performs RF transmit processing on a transmit signal and generates the transmit wireless signal from it. A host processor communicates data, status and control information with the RF device via a bus, the host processor includes host based software application and a host based modem application. The receive signal generated by the RF module over the bus and generates receive data in response to it input to the software application at a output by the software application is received and generates the transmit signal in response to it, sending the transmit signal to the RF module over the bus. The figure shows a block diagram illustrating an analog cellular communications systems tuned for data communication.
