In the course of studies structural sensors for monitoring schemes cover mobile network operator's area are proposed. Three main types of sensors are developed, which are intended to be placed on transport and stationary. Sensors collect data about the state of the cellular network signal into the measurement location and shipment to Web-Server is made. The main transmission channels from the sensors are controlled by the mobile network. For backup cellular networks of other operators or other standards are used, as well as other means of access to the Internet (wired connections, such as xDSL or wireless, such as Wi-Fi). Implementation of the proposed sensor circuit can reduce the costs of monitoring a mobile network and increase the accuracy of the information about the network state.
