Supported GSM radio frequencies

The MP modem has tri‐band capability on HSUPA and UMTS networks, operating on:

•850 MHz

•1900 MHz

•2100 MHz

and quad‐band capability on EDGE and GPRS, operating on:

•850 MHz

•900 MHz

•1800 MHz

•1900 MHz

Connection methods

You can connect the MP modem to a USB, Ethernet (RJ45), or serial (DB9) port on a computer. When connected to a USB or Ethernet port, the MP modem behaves like a network card.

When connected to a serial port, the MP modem behaves like a dial‐up modem.

The MP modem also supports connections via IEEE802.11b/g (MP595). See Chapter 6 for more details.

Virtual serial port

The MP modem supports four virtual serial ports (VSPs). Three are reserved for internal use by the MP modem. The remaining VSP, which is called Sierra Wireless Application Interface 2, is assigned to a specific COM port that varies between users. This VSP can be used, for example, to send AT commands, or to run applications such as HyperTerminal→.

Special MP modem modes such as GPS that are supported on a serial port are also available on the virtual port. For example, with the virtual port enabled, a mapping application on your computer that normally listens for GPS messages on a serial port listens for those same messages on the virtual port.
