Allowing shared use of licensed spectrum by third parties is not expected to be part of the United Kingdom’s release of new 3.5-GHz spectrum for 5G and other uses.
“The US’s proposal to do CBRS (Citizens Broadband Radio Service) is an interesting one, but it is not something we are considering for this band,” said Philip Marnick, Ofcom group director. In other words, spectrum sharing will not be the allocation method. On the other hand, as Marnick notes, “about 58 percent of all spectrum is shared by different types of users.”
“We have also consulted about and are looking at sharing in the 3.8 to 4.2 GHz band, which today is used by receiving satellite earth stations and by fixed links,” said Marnick.
Though licensing rules are not yet in place, it is expected that some of the 3.5-GHz spectrum will be made available on a licensed basis and some on a license-exempt basis. At least conceptually, it is possible that higher-frequency millimeter wave spectrum (26 GHz, for example) could be made available to enterprises on an unlicensed basis where access is highly localized, while wide area applications might be licensed, he said.
