Page 8: Introduction
LMR400 delivers a reliable radio link at up to 38.4 kbps over the air for the 25 kHz channel spacing, 30 kpbs for 20 kHz, 19.2 kbps for 12.5 kHz, and 9.6 kbps for 6.25 kHz. The module requires a regulated DC voltage power supply 4.2 V ±...
Page 9: Operating At Ultra High Frequency Band
Operating in UHF frequency band will provide a non-line of sight connection. User selectable operation mode (licensed or unlicensed mode) is a feature, which makes LMR400 system suitable for both licensed and unlicensed markets. Relatively low cost associated with installation equipment compared to the licensed wireless bands, since no capital is required to purchase spectrum rights.
Page 10: Specifications
Operating Modes The operating modes for LMR400 can be set through the CLI, and/or through AWLaunch. The following oper- ating modes are available for LMR400 : • The sleep mode has automatic transmitter activation by an internal real-time clock, or by an external controller through the data interface control lines (RTS and DTR), or by the triggering of the external Sense Inputs.
Page 11: Antennas
Antenna type depends on the site requirements, and may be directional or omni-directional. Note that to sup- port 8 miles distance range between Base station and LMR400 unit, an antenna mast should elevate the base antenna a minimum of 20 feet above the average level of the terrain.
