Dual Band Communications Hubs

A smart metering installation usually includes gas and electricity smart meters, an In Home Display (IHD) and a Communications Hub (Comms Hub). These devices communicate with each other via a Home Area Network (HAN) which is generated by the Comms Hub. 

The current Comms Hubs have a single band 2.4 GHz HAN frequency and are known as Single Band Comms Hubs (SBCH) and should provide HAN coverage in approximately 70% of premises. For some buildings like blocks of flats or where walls are very thick, the smart meter can't communicate with the Comms Hub. So in 2020, a more sophisticated hub with a choice of frequencies started being installed. These are called Dual Band Comms Hubs. They use a HAN frequency of 868MHz along with the existing 2.4GHz frequency. Dual Band Comms Hubs (DBCH) are expected to increase coverage to 96.5% of premises. These hubs will enable millions more British homes to benefit from smart metering.
