Introduction
Topics covered in this introduction include the RIM 801D OEM radio
modem features and an introduction to DataTAC network technology.
Radio modem features
The RIM 801D OEM radio modem is specifically designed to integrate
easily into a computer or other embedded system, such as PDAs, vending
machines, and point-of-sale terminals. Operating in the 800 MHz frequency
range, the RIM 801D is compatible with DataTAC wide-area wireless data
communication networks.
Powerful and efficient transmitter
The RIM 801D provides reliable transmit efficiency throughout the range of
operational voltage (6.0 to 9.5 volts). This is an important feature because
the radio modem does not lose transmit power as battery voltage drops,
thereby keeping the radio coverage area at a maximum throughout the life of
the battery. The chart below shows how the transmit power output remains
constant over the 6.0 to 9.5 volt supply.
