Wireless duplex mobile communication system network, what automatically complete the synchronization of the work of the centers

Currently the latest wireless LAN standards I. Cellular mobile communications (1) operating frequency band: 1710-1755MHz and 1805-1850MHz II. Cellular mobile communications (2) operating frequency band: 1865-188OMHz and l945-1960MHz The above two operational frequency bands as the public cellular mobile communications frequency band, by the State Without Commission in accordance with the public cellular The above two service frequency bands are allocated or assigned by the State Council in accordance with the application and actual demand of the public cellular mobile communication operating units. Wireless access (FDD mode) (a) Operating frequency bands: 1800-1990MHz and 1960-1980MHz (b) The above frequencies are used for public communication networks, and shall be allocated or assigned by the State Council in accordance with the application and actual demand of public communication operators. Wireless Access (TDD mode) (a) Operating Frequency Band: 1900-1920MHz (b) Frequency assignment and management authority for approval of stations (networks) shall be carried out according to the current management measures for microwave communication stations. V. Spread Spectrum Data Communication (a) Operating frequency band: 2400-2483.5MHz (b) The authority for approval and management of stations (networks) shall be implemented in accordance with the current administrative measures for microwave communication stations. The relevant technical specifications of the first to fifth items of the above services are formulated separately by the Office of the State Council of the People's Republic of China. Sixth, multi-channel microwave cable television transmission system (MMDS) working band: 2533-2599MHz seventh, radio positioning working band: 2300-2690MHz eighth, microwave relay communication working band: 2300-2690MHz ninth, industrial, scientific, medical equipment, wireless electromagnetic radiation band: 2400-2500MHz the above sixth to the ninth item The management methods and technical specifications for the application and approval of the business shall be implemented according to the current regulations. X. Since it is difficult for mobile services to be compatible with microwave and radiolocation services in the same frequency band, therefore, in the areas where the two have influence, the mobile communication services will be set up by the network unit and the existing microwave or radiolocation equipment using units (holders of radio station licenses) to cooperate, and in the light of the principle of safeguarding the demand for the development of mobile communication services as well as the principle of proper handling of the existing equipment, to take the methods such as changing the frequency of the equipment, substitution and economic compensation to solve the problems. To be resolved.
