Its by my country39。s thirdgeneration 3G mobile munication with international standards, is the world39。s thirdgeneration mobile munications recognized international standard. Is the first time China put forward a plete munication system standards and is internationally recognized, is a breakthrough in the field of munications standards. TDSCDMA, whose main research studio indoor coverage, propagation model and its parameter value, capacity, system coexist, dry place. Keywords: TDD mode。 signal weak areas。 cellular base stations。 indoor cover
