Description
Technical field
The present invention relates to mobile communication technology field, particularly one is applicable to the demand signals amounts such as community, elevator, public venue, basement, hospital greatly, the mobile communication micro-power digital multiple spot indoor covering system of the occasion that demand is special.
Background technology
Along with the development of mobile communication technology, mobile service becomes increasingly abundant, userbase rapid amplifying.Statistical communique according to the up-to-date issue of Ministry of Industry and Information shows, and ends for the end of the year 2012, China cellphone subscriber more than 11.12 hundred million families, popularity rate reach 82.6 hundred people, exceed global average level, wherein 3G mobile communication subscriber will reach 200,000,000.Calculate according to the population base of China, cellphone subscriber and 3G mobile communication subscriber are also by sustainable growth.Urbanization in China is in develop rapidly in recent years, and a large amount of population pours in city, and in city, the hot spot region density of population constantly rises.In 2G mobile radio communication, the telephone traffic more than 60% and data service occur in indoor; Data service more than 70% in 3G network also occurs in indoor.The surge of number of users and city indoor telephone traffic density, has better in-door covering ability in the urgent need to mobile communications network, to improve the oeverall quality of network.
Exceed more than half traffic due to current mobile communication and data all occur in indoor, in-door covering obtains the extensive attention of operator, improves the quality of in-door covering and increases the capacity of in-door covering, having become the emphasis of all mobile network optimization work.China Mobile, CHINAUNICOM the medium-and-large-sized building in the city such as Beijing, Shanghai 2G (GSM) network in-door covering rate exceeded 90%, the in-door covering rate of 3G is then relatively little, in the case, how original 2G indoor covering system is transformed, make its support 2G, 3G even 4G become Virtual network operators urgent problem.
