Provincial Wireless Ad Hoc Network

By deploying wireless ad hoc networks over long distances, we aim to achieve full coverage of in vehicle communication in provincial areas.

Urban coverage wireless ad hoc network

In any city of any size, establishing a single high-point digital trunking communication system base station can achieve full coverage for vehicle-mounted base stations. Setting up three high-point digital trunking communication system base stations can essentially achieve full coverage for mobile handheld terminals. On the basis of a network of three base stations, expanding the coverage area does not require additional frequency resources, and supports unlimited addition of coverage base stations, making it easy to achieve full indoor coverage across the entire city.

Urban Emergency Communication Wireless Ad hoc Network

In a city, by selecting a high point over 200 meters to construct a digital trunking communication system base station, only a pair of dual-frequency channels needs to be configured to achieve over-the-horizon coverage of the entire road surface of the city. Establishing three high-point digital trunking stations can cover a diameter of 60-100 kilometers. This setup does not require additional single-frequency resources and supports city-wide, high-capacity direct communication between handheld radios. In the direct communication mode of handheld radios, the command center can at any time make individual calls, group calls, and prioritize or interrupt calls to any radio, supporting dynamic positioning of all radios. Through the relay of vehicle-mounted mobile base stations, it is possible to cover buildings of any size, any height, underground parking lots up to two levels deep, and subway station platforms.
