Abstract :
There is a growing need for cellular network performance surveys in an increasingly competitive cellular phone environment. New operators are under great pressure from their share holders to bring their network up for commercial service but at the same time they do not want to compromise their service quality. For existing operators, the drive is to achieve optimum spectral efficiency for the growing traffic demand in their preciously allocated spectral band. The motivation is threefold, (1) to quantify network performance and operating parameters, (2) to investigate specific network problems, and (3) to optimise the network. The Surveyor is designed to enable engineers to perform field surveys in these areas with ease. It is a proven system helping operators over the world to capture and analyse cellular data which enables engineers to constantly monitor, improve, and refine a cellular mobile network´s quality of service. The Surveyor is an advanced continuous (or carrier) wave (CW) and handset survey system which features full handset message decoding in real-time for up to eight or more handsets of the same or different types. It can interface to practically any Global Positioning System (GPS) navigation system and also supports other navigation systems
