Chinamobile has built TD-SCDMA and GSM two networks.In the future of TD-LTE system construction
if it can share antenna with TD-SCDMA
it needs not to increase pole.We only need to replace the TD-SCDMA antenna.It is more convenient for project.This paper investigates the coverage of each system and the data transmission performance using dual-band antenna through testing in outdoor coverage of TD-SCDMA and LTE two systems.
