Nearly all meter being currently installed are SMETS 2. To this end the DCC plan to have 4G single band Communications Hubs available in 2023, with dual band to follow in Q2 2024.
This change will require the replacement of communications hubs on the Smart Electricity Meters in the Central and Southern regions of the UK. This includes Telefónica (O2) who provide the Smart Meter communications for the Central and Southern regions of the UK.

The government and UK mobile network operators have agreed to phase out 2G and 3G mobile networks by 2033 in order to free up bandwidth for 5G and future 6G services. In a cellular system, geographical areas are divided into regular shaped "cells".Īdditionally Telefónica also use local mesh networks to fill in the mobile coverage gaps.īy 1 st January 2021 Telefónica had achieved their maximum contracted coverage of at least 99.25% in the Central and South Regions, achieving 99.25%. This system is commonly used by mobile phones. The 2G/3G cellular radio communications network is used by Telefónica (O2) in the rest of England and Wales.
Communication towers communicate directly with smart meter Communications Hubs in homes.īy 1 st June 2020 Arqiva Limited had achieved their maximum contracted coverage of at least 99.5%, achieving 99.55%. The LRR system uses infrastructure and technology similar to that already used for other important national communications networks, such as those for emergency services and keeping lifeboat stations connected. Long-Range Radio communications (LRR) is used by Arqiva Limited in Scotland and the North of England. North and South Communication Areas Scotland and the North of England This form of communications looks like a mesh when you draw out the possible links between meters and is therefore known as a Mesh network. Sometimes your comms hub will communicate directly with DCC and sometimes it will talk through other comms hubs around you to reach a particular comms hub which has direct communications with DCC.
Depending on the Communications Service Provider (CSP), which varies by areas of the UK, the technology can change depending on what works best in a local area. This company will usually be the Data Communications Company (DCC) which the government has set up especially for the role of supporting SMETS 2 meters. The Smart Metering Wide Area Network (SMWAN or WAN for short) is the name given to the communications network between the communications hub sitting on top of your electricity meter and the company responsible for collecting the data and passing it on to other businesses such as suppliers. A more modern communication network is used with these meters and all suppliers will use it this - keeping your smart meter smart when switching suppliers. SMETS 2 This specification is more advanced and meters were first rolled out in 2018. There are two main types of smart meters - the older models known as SMETS 1 (Smart Meter Equipment Technical Specifications) and the newer versions that were rolled out in 2018, known as SMETS 2.
