Frequently Asked Questions
Who is responsible for the communications hubs?
Smart DCC handles the ordering and delivery of Communication Hubs to Energy Suppliers and their agents who fit them during the smart meter installation.
Smart DCC also manages and verifies the available Communication Hub firmware variants.
Who is responsible for installing and supplying the communication hub?
A communication hub is installed in homes and businesses to connect Smart DCC's secure network to smart gas and electric meters and allow smart meters and in-home displays to connect to each other across the Smart Meter Home Area Network (SM HAN).
The communication hub then connects to the wide area network (WAN) that carries the data to energy retailers and other DCC customers.
What wireless networks do communication hubs connect to?
In central and southern regions, cellular and wireless mesh technology (provided by Telefonica) will be used to connect to the SM WAN, while in northern regions, the communications hub will use long-range radio (provided by Arqiva) for wide area communications.
What type of communications system does the communications hub and smart meter use?
The communications hub and smart meter uses Zigbee to connect to each other and the DCC network. It is simple, inexpensive, low power and secure.
The range of this technology is about 15m, but this is reduced by obstructions such as walls and doors.
As a result, sometimes a standard communications hub cannot connect to the DCC network. To get round this problem, DCC have developed a new type of communications hub called a dual band communications hub.
