The TeslaEXT is a standalone radio endpoint that connects to an encoder or pulse register through a communication cable and passes collected meter information to an automated meter reading system with an unlicensed 1-watt transmission. The TeslaEXT is powerful and works extremely well in an AMR drive-by system or an AMI fixed network. Because it is installed at the top of the meter pit in the meter box lid, it is the best choice for unlicensed AMI meter reading.
