The LTE1800 system is a standard LTE-based system, and is mainly different from public network application in the application of the industry in using different frequency bands, four major links of a chip, a system, a terminal and a test which form an industrial chain are completely the same as those of the public network system, compared with the LTE230 system, the technology is mature, the available bandwidth is larger, high-speed service can be borne, the access requirements of more users are met, but the system is influenced by high frequency, the system coverage area is small, and the network building cost is higher. In view of the complementary advantages of the two systems, the two systems are subjected to pilot frequency hybrid networking, the LTE230 system is used for realizing wide area coverage, and the LTE1800 system is used for realizing hot spot coverage, so that the method has important significance for improving the quality of the power wireless network and improving the service carrying capacity.
In addition, at present, a part of cities have built LTE (Long term evolution) government-enterprise networks based on 1.4GHz, the coverage range is wide, the wireless network whole-network coverage of the whole area cannot be realized due to the service dispersion characteristic and the network construction coverage strategy of a power system, particularly a power distribution scene, the network system and an industry network are shared, the wide coverage and high bandwidth characteristic of the government-enterprise network can be effectively utilized, more service access requirements are met, and the method has important significance.
The power business can be divided into power transmission and transformation scene business and power distribution scene business, for the power transmission and transformation scene business, especially power transmission business, because of the chain network architecture characteristic, the coverage mode of honeycomb does not meet the business distribution characteristic, the network construction cost is higher, and the power transformation business, because it is distributed in the transformer substation, and the existing transformer substation has abundant optical cable resources, the short distance wireless communication technology is mature, and the business access has various network choices; for a distribution and power utilization scene, for a distribution service, due to the distribution characteristics, the characteristics of wide coverage, low density, low rate and the like exist, the optical cable resource cannot meet the access requirements of various service nodes, the intellectualization of the distribution service is an important factor influencing the quality of power service, the service experience of power users is directly influenced, the communication requirements of various services such as distribution automation and the like are very urgent, for the power utilization service, due to the fact that the number of access nodes is large, the coverage area is wide, the coverage cost is too high due to the adoption of an optical fiber communication mode and the construction difficulty is too large, and currently, the optical fiber communication mode is mainly adopted for bearing.
