Engineering experts are pleased with the successful completion of measurements of the indoor coverage of 5G signals in some of the first tests of its kind carried out in the country at the University of Sussex earlier this summer.

The tests are an important step in establishing the capability and ironing out issues with 5G which is expected to be commercially available as early as next year in the US and by 2020 in the UK.
