What is the “maximum communication distance” and the “maximum number of devices” possible with Echelons power line transceiver solutions? Why doesn Echelon list such specifications?
In power line systems it is difficult and sometimes not meaningful to specify “maximum communication distance” or “maximum number of devices.” This is because communication distance is dependent on the wiring, topology, and type of devices already on the network at any given time and their noise and distortion characteristics. All of these impediments are unique to a given power line network and could vary widely from one environment to another. As a result, the “maximum communication distance” will also vary from one environment to another. For example, Echelon’s power line solutions are used in freight train braking applications where the device-to-device distance is up to 1.6km. On the other hand, they are also used for communication with off-shore oil platforms where the devices are up to 20km apart! As far as in-home applications are concerned, Echelon’s power line solutions were designed to support reliable communication between devices in typical homes (< 5000 s foot / 465 s met
