Design of a triple-band scanner for TD-SCDMA network planning and optimization

TD-SCDMA is one of the third generation (3G) mobile communication standards, which is coming into the commercial phase. Along with the network deployment, planning and optimization tools are playing an important role to ensure the network performance. Scanner is one of the important tools, contributing to optimize the wireless network performance via drive test, tower site survey, in-building measurement, base station monitoring, and post processing. In this paper, we developed a triple-band TD-SCDMA scanner. It has a robust ability of fast measurement on multi cells in the same frequency, benefit from an efficient interference cancelling algorithm.
