2. INTERNET BRIDGEUsing this model, mobile phone or cordless modem acts as modem to PC, providing dial-up networking and fax capabilities without need for physical connection to PC.The dial-up networking scenario of this usage model needs a two piece protocol stack. AT-commands are needed to control the Mobile phone or modem and another (PPP over RFCOMM) to transfer payload data.The fax scenario has a similar protocol stack but PPP and the networking protocols above PPP are not used and the application software sends a fax mail directly over RFCOMM.
