Plextek has developed a new radio telemetry system targeted at efficient automatic remote reading and smart metering applications. The system is based on Plextek's Ultra Narrow Band (UNB) telemetry platform, which enables meter manufacturers and meter reading companies to implement a proven and efficient radio technology without a SIM or the network uncertainties associated with mesh radio. This will also help make a significant contribution towards meeting the ambitious targets set out by European Governments for reducing carbon emissions from homes.
Plextek’s UNB technology is optimised for long distance, low power applications where the data transmission rate is low. The remote metering offering comprises a cost-optimised base station and a small low cost telemetry module for integration into the client’s meter or other equipment. It is available in licence free 868MHz or 915MHz frequency hopping variants and can be modified to operate in other bands. Plextek is also able to offer design services to optimise the form factor and interface of the telemetry module to the client’s requirements.
A typical system includes a network of base stations, each communicating with many thousands of meters, and backhaul by ADSL or other fixed IP network to the control and billing centre. The technology is bi-directional, allowing smart metering so that the meter can receive information from the network such as billing, credit or control data.
