Background:
  Kaili long-term commitment to international and domestic users with special wireless system in urban rail transit equipment and services, has the first-class technology and service team. Long-term for subway service experience, with a deep understanding of rail transit operation management mode and mastery of core technology, we based on independent intellectual property rights KaiLiTETRA system platform to build the advanced KaiLi orbit transportation special wireless communication solutions. This solution has the characteristics of safe, reliable and efficient, and implements the 100% of the localization, will become urban rail traffic safety, high density, high efficiency operation a powerful guarantee.

Stories
rail transit special wireless communication system based on KaiLiTETRA digital trunking system platform, integrated rail transit signal system of train position information \ trains, developed a set of automatic dispatching communication system. System controlled by the exchange center, base station equipment, schedule, equipment, network equipment and user terminal equipment, etc. For fixed users (control center, car depot/parking dispatcher, station attendant, etc.) and mobile users (the train driver, disaster prevention, maintenance personnel), voice and data exchange of information between provide a reliable means of communication, it is safety, improve transportation efficiency and management level, improve the service quality provided important guarantee. At the same time, the abnormal situation in urban rail transit operation and cable communication failure, can quickly provide disaster relief and accident treatment such as command post to wireless communications.

Main Function
·scheduling functions: group calling, single shout shout, emergency call, information group, dynamic reconfiguration, telephone, Internet, short data and status messages, IP packet data, radio calls, etc.;
·enhancements: train number caller to an automatic train dispatching, train the number to call, attribution, train position update, station district call, clock synchronization and so on, so the dynamic recording;
·full of single station clustering;
·the integrated network management.

Main feature
·rich in scheduling function, can be customized;
·switch different disaster tolerance, improve the ability of disaster system;
·multipriority service;
·high channel utilization;
