Siretta has created a cellular signal analyzer. This handheld tool allows the user to survey the cellular signal in a particular location. The data retrieved can be broken down by base station, mobile network operator, network level, and all visible cells. This data shows not only the signal strength, but if there are sockets available. This tool will show the user which carrier is best available and will be the most reliable for them to use. The Snyper LTE Graphyte is available in a US and European model.
