In the mobile communication network , the main part by the macrocell base station system to provide a comprehensive network coverage . But from the point of view of investment, construction period , the program is not the best way to simply use the base station network covering . Repeater provides extended coverage cost-effective and reasonable solution to the contradiction between the network capacity , network coverage and investment in order to achieve the minimization of network investment and to maximize efficiency has a larger advantage . Repeater (Repeater) has been one of the special application of wireless network coverage solution , is designed to extend network coverage , mainly in the microwave, GSM , CDMA , WCDMA , TD -SCDMA network address indoor depth coverage to resolve low- traffic areas ( such as isolated villages and towns , highways , tourist spots , etc. ) coverage, to solve problems due to local topography, surface features caused by the shaded area coverage . Repeater own characteristics introduced in the network will bring the impact of interference , delay , repeater improper application and technical defects on the negative effects of the network to the network caused by the bad influence . In this paper , the Telecom CDMA repeater and base station Hungezuwang technology research , first of all start from the basic theory of the repeater , detailing the application method and its base station repeater , and then combined with the background statistics, the outdoor signal test data the level of engineering practice , focusing on analysis of the the noise introduced Repeater CDMA network base station , repeater delay caused by network parameters such as search window , and gives the solution ideas .
