Electric Smart Meter

LoRa® is a long-range technology for the IoT. It is an open system that allows anyone to manufacture devices which can communicate over a LoRaWAN® network. The openness removes the hand-cuffs that restricts companies to a particular vendor. With LoRa, utilities can design their system to facilitate communicating with electric, water and gas meters all on the same network. Other devices like street light controllers, transformer temperature monitoring, load control devices and demand management system can all coexist within LoRa.

LoRa® is designed for low power, long range applications which are well suited for AMI. It operates in the 900Mhz ISM bands but the technology allows its signals to transmit above the noise in these bands. Vision’s system transmits a maximum of 42 bytes at just under 400ms using 1 watt of power (30dbm) radios. LoRa technology allows meters and other devices to communicate up to 20 miles.

The technology is scalable to the size of your requirement. You can choose from 8 to 64 channel gateways. It is also possible to receive up to 12,000,000 messages per day with a 64-channel gateway. Gateways are available from several manufacturers.

Any system other than one supported by LoRa® will handcuff you to a single vendor for 15 to 20 years. This technology allows you to competitively source meters, infrastructure and software from the best and most competitive sources.
