| Femto technology of indoor coverage is defined as a small, low power3G base station access technology, used for home and Office Interior, with the help of fixed broadband access for indoor3G mobile business, is the complement of3G network for indoor coverage. Is essentially an extension of the fixed-line broadband on the3G network, is a typical fixed-mobile convergence products, devices compact, works in authorized band, covers a radius of5-20m;3G cost close to VoIP for voice costs;3G data bit cost close to fixed-line broadband. In large networks based on family/unified billing rates provided on the basis Enterprise Femto coverage area, such as the exact location of billing.This article through a comprehensive exposition of Femto technology of indoor coverage performance principle and application of the system in Tianjin, China Unicom, by analyzing the recent application of Tianjin Unicom Femto network typical of resolving a case, on its network applications, network quality with an in-depth grasp. Networking scheme of various wireless networks relatively poor environments, from mobile3G network, radio coverage, CS, and PS domain, and net constituted the other aspects, especially significant impact of network and user service-aware of a detailed in-depth analysis.This article for reached improve Tianjin Unicom3G network run quality and for Tianjin Unicom3G user provides quality network support of purpose, using above analysis research results, relies on moved business of network optimization technology knowledge and engineering maintenance experience, through for road measuring, and observation analysis data, and developed resolved programme, network optimization method, for wireless covering blind spots for has network optimization programme of design developed and engineering implementation, and select number a Femto technology commercial network for instance analysis, Further validation of Femto technology on3G network technology advantage. |
