In June/July 2025 DCC consulted on proposed changes to the Intimate Communications Hub Interface Specification (ICHIS) to include the remainder of the 4G 800MHz frequency band and the 4G 700MHz frequency band, creating the potential for future flexibility in this service.
This is the conclusion to that consultation - responses were supportive of the proposals and changes have been made to the ICHIS.
The ICHIS is a technical document that defines a common interface between Communications Hubs and Smart Meters.
