Research on Service Support Ability of Power Wireless Private Network
摘要
Abstract
Aiming at problems in application of power wireless communication and to better serve smart grids and develop application research on time division long term evolution (TD-LET) technology in field such as electric pow er communication, this paper analyzes framew ork of the w ireless private netw ork and the service model of pow er services on the basis of basic principle of TD-LTE netw ork structure.Taking actual cases for examples, it compares technical parameters of LTE systems w ith frequency bands of1.8 GHz and 230 M Hz and results of theoretical analysis and field tests by means of data processing and comparative analysis.M eanw hile, it verifies support ability of the pow er w ireless private netw ork for pow er services and analyzes advantages and disadvantages of tw o systems and their applicable scenes.It draw s conclusions that the LTE230M system has certain covering advantages in those surburbs and rural areas and is suitable for construction of private netw orks w ith few er business terminals and in small particle areas, w hile the LET1.8G system is more suitable for construction of private netw orks in cities and large particle areas.关键词
