Ofcom has approved a request by
TalkTalk to vary its licence for 3.3MHz of radio spectrum in the 1800MHz “DECT guard band” (1781.7-1785MHz paired with the 1876.7-1880MHz block), which supports the ISP’s plan to add small cell / femtocell based
4G (LTE) Mobile into its broadband routers. The regulator also hopes to open the band up more generally to other uses.
