U.K. regulator launches new consultation, publishes framework for sharing frequencies.
Ofcom is seeking input on whether spectrum in the 3.8 GHz-4.2 GHz band could be shared in order to free up more capacity that could be potentially used for wireless broadband.
The frequencies are currently used for fixed satellite services and point-to-point connectivity for things like backhaul. Fixed-wireless operator UK Broadband also uses an 84 MHz chunk of 3.9-GHz-4.0-GHz spectrum for its Relish Internet service.
"We believe this band poses a good opportunity and potential for more intensive usage by innovative applications/services, while taking into account incumbent services," said Ofcom, in its consultation document.
The U.K. regulator’s initial thoughts centre on allocating licences on a geographic basis, and providing opportunistic spectrum access (OSA) provided it doesn’t cause undue interference.
"Where there is potential benefit to new sharing we will need to consider the associated changes carefully, taking account of the benefits that incumbent services deliver to citizens and consumers," Ofcom said.
The consultation will close on 9 June.
Meanwhile, Ofcom has also published a framework that sets out how it will consider the potential for sharing frequencies when allocating spectrum in future.
The framework considers what the spectrum is currently used for and what it could be used for going forward. It also looks at any barriers that may limit the extent of current or future sharing opportunities, and any regulatory or technical tools that could be used to facilitate new or more intense sharing of frequencies.
"The framework will continue to evolve over time, as a result of market and technology developments," Ofcom said. "Its application requires judgment to identify which barriers, tools and enablers may be relevant and which spectrum options may be suitable, in line with the characteristics of use in a particular case."
