Police force, fire brigade, ambulance and other security forces demand quick, accurate, secured and reliable mobile communication. Security systems and fire alarms operate non-stop around the clock, as well as Mobitex. Using wireless connection, there is no worry for the cables being cut by burglars or unable to survive in fire. The Mango technology was designed just for such mission-critical tasks. A comprehensive mobile dispatch solution can be easily achieved with MangoCombo as handheld terminal, and MangoLink for vehicular use.
