Abstract
This invention relates to a roadside emergency system. The systems includes a roadside station which has a telephone unit similar to a mobile telephone set for a cellular mobile telephone system. When the unit is activated, it automatically generates radio signals which cause a mobile telephone switching office to dial up an emergency station (such as a highway police station). The office also automatically establishes a channel for voice communication between the roadside station and the emergency station. The roadside station is further provided with a back-up battery and an alarm to prevent tampering.
