The MP modem has a rugged design that allows it to
withstand the vibration, shock, humidity, and extremes of
temperature experienced in the normal operation of police,
emergency, utility, and field service vehicles.
You can use the network connection provided by the MP
modem to access shared data, browse the Internet, and send
and receive e-mail and text messages. The MP modem also
allows for sensors, gauges, and alarms (such as panic buttons)
to be installed in vehicles and remotely monitored from a
central location.
