The GSP-1600 delivers clear digital voice and data communications virtually anywhere, combining Globalstar CDMA Satellite, Cellular Digital CDMA* (800 MHz) and Cellular Analog AMPS* (800 MHz). Globalstar Tri-Mode phones are designed with the flexibility to meet the needs of customers who already depend on wireless communications but find themselves in areas where cellular or radio coverage is either unavailable or inaccessible. The Globalstar Tri-Mode phone is designed to complement existing fixed and cellular telephone networks by switching from terrestrial cellular telephony* to satellite telephony as required. These features provide the Globalstar user the highest level of service and convenience. The GSP-1600 Tri-Mode phone offers an ergonomic design that makes it comfortable for hand-held operation. The phone measures 400cc in total volume and weighs 384 grams. The height is 177 mm, the width is 57 mm and the thickness is 48 mm (excluding the cellular antenna). The antenna, when held in a vertical position, communicates with the Globalstar satellite at elevations more than 10 degrees above the horizon.
