Wireless Communication Modem

摘要

A wireless communication modem (2) receives data (10) sent from a host device (4) in a nonprocedural manner, then subjects the received data (10) to protocol conversion, and transmits the converted data to a server (8) via a wireless communication network (6). The wireless communication modem (2) has an on-request transmission mode in which the data (10) is transmitted to the server (8) only when a connection from the server (8) to the wireless communication modem (2) is established.
