As the mobile cellular market becomes saturated, many operators are striving to reduce system operating expenses (OPEX) and will continue to do so. The first step to sustain the quality of cellular radio network is securing normal operation of the base stations. DABIN Systems provides antenna and cable testing equipment, which are crucial factors in ensuring RF signal quality, and provides devices that analyze the base station signal to determine whether it is in normal operation or not so that the mobile cellular network operator can secure the quality of the wireless network and hence reduce operating cost.
