our 5G network will empower the 5th Generation.

The power of 5G on personal and business devices will give everyone a better and more reliable connection in busy places, delay-free downloads and buffer-free streaming. However, it’s 5G’s impact on the world around us that’s even more exciting. This new technology has the power to connect buildings, transport and services in ways we’ve never seen, completely revolutionising everything from the way traffic flows on our roads to the way we receive health care. We are working with major UK networks to test the technology’s potential capabilities and will keep you up to date with any exciting information we get.
