Wide-area-network wireless modem with embedded communication protocol

摘要

A wireless modem is connectable to a user device, in which application software is "wireless unaware" and does not require an application programmer to consider particularities of wireless communication protocols, via a serial port. The serial port of the wireless modem receives user data transmitted by the user device in accordance with a communications protocol for wireline transmission. An output port of the modem is connectable to an antenna. A processing unit is coupled to the serial port and the output port and includes an embedded communication protocol for wireless data communication. The processing unit processes the user data received from the serial port in accordance with the embedded communication protocol.
