Abstract
A standard interface for interfacing a wireless modem assembly with a host device comprises a primary serial interface, a secondary serial interface, and a differential serial interface for supporting communication between the wireless modem assembly and the host device. The standard interface can be implemented in a standardized connector, such as a 70-pin connector having unused pins for future feature expansion. The standard interface also provides for other interfaces including, for example, power, modem status, audio, voice, general purpose input/output, and subscriber identification.
Claims44
A wireless modem, comprising:
- a standard wireless modem assembly including a standard interface for interfacing the wireless modem assembly with a host device, the standard interfacing including
- a primary serial interface configured to support data communication between the host device and the wireless modem assembly;
- a secondary serial interface configured to support data communication between the host device and the wireless modem assembly or to support data communication internal to the wireless modem assembly;
- and
- a differential serial interface configured to support data communication between the host device and the wireless modem assembly using a differential signal pair;
- and
- a core module configured to be removably secured in the standard wireless modem assembly;
- the core module including a radio frequency section configured for interfacing the wireless modem to other devices over a wireless communication channel and a baseband section configured for communication information between the host device and the other devices, the core module further being configured to communicate with the host device through the standard interface.
A wireless modem, comprising:
- a standard wireless modem assembly including a standard interface, the standard interface including:
- a basic function interface configured to provide at least one serial data communication interface between a host device and a wireless modem assembly;
- a SIM interface configured to provide a data communication interface between the host device and a SIM card included in the wireless modem assembly;
- and
- an audio interface between the host device and the wireless modem assembly;
- and
- a core module configured to be removably secured in the standard wireless modem assembly;
- the core module including a radio frequency section configured for interfacing the wireless modem to other devices over a wireless communication channel and a baseband section configured for communication information between the host device and the other devices, the core module further being configured to communicate with the host device through the standard interface.
