TD-SCDMA-Radio Network Planning Design Of Zhengzhou

As the 3G standard that the Chinese independence develops, TD-SCDMA compare WCDMA network programming research start lately, its network programming is placed in a beginning stage.The TD network construction faces a series of difficulty and problem currently, but because the industry standard isn't perfect, not mature,2 G/3 G is strictly excellent to turn complications of a high stage, programming experience not enough etc makes the network overlay become one of the initial difficulties.Particularly TD-SCDMA, is one new of technique, because of don't originally possessed the backlog of network, how reasonable work well the programming of network with excellent become to a anxious need the topic of solution.The TD-SCDMA wireless network planning and programming design is the stage of the TD-SCDMA network construction essential to have, network programming of the quality will directly influence the function, network of construction cost and maintenance cost.The TD-SCDMA network programming and other wireless networks program similar, equally need to consider various factors, the network programs process basic consistent;But because of its special technique characteristics, its wireless net programming has a different contents and characteristics again.This text passes the introduction to each stage of wireless network programming design and useds for guiding a network programming design, the exaltation programs an efficiency.This text elaborated first that the key link in the wireless net programming includes a wireless network to prepare a programming, the wireless network small area programming and district a programming and face the area programming, frequency programming, and code programming...etc..Then the standard and overlay manage a standard both side point from the system quality consideration, and specially aim at some point the contents carry on elucidation.Include:The adjustment of antenna;Modify a radicle station to border on to gather;Modify the radicle station o code, reduce a code word interference;To overlay the blind area provide for programming suggestion;The check keeps putting to stand to bring network of interference;Solve overlay radicle station in the indoor and outdoor radicle station to border on an area problem;The parameter is excellent to turn and make to connect to go into, cut over etc. the parameter Be superior to turn.The problem of the cutting over of failure high rate of the TD-GSM different system switching,finally analyzed in the Zheng Zhou's the downtown TD-SCDMA wireless network programming to meet in the text, the downtown partial road inside the TD net weak overlay phenomenon, and because of GPS mold piece the breakdown and GPS antenna problem causes of time of radicle station synchronous problem, and carried on a detailed research, finally gave related solution.
