Motorola and Nextel announced the launch of the Motorola i325 IS handset, which offers Direct Talk, a back-up walkie-talkie service launched in December that Nextel customers can use when they are outside the carrier’s coverage areas. The service provides a range of up to six miles (though terrain, weather, foliage and use in vehicles or buildings could diminish range).

The i325 IS handset complies with Military Standard 810 F for blowing rain, humidity, dust, shock, vibration, temperature and air pressure extremes, solar radiation and salt fog, the companies said. It is approved in environments where flammable gases or vapors may exist, a sealed bottom connector cover to protect against liquid or dust damage, a fixed antenna, and offers GPS-based location capability.
