The term G.mgfast has been rapidly replacing the Nokia-inspired term of XG.fast over the past six months, and standardization at the ITU is set to complete during mid-2019. This is related to the emergence of 5G, which will either rely entirely on fiber for small cell connection – and therefore create costs which are out of reach of most telcos – or leverage existing copper lines, which can be upgraded in parallel with the roll-out of 5G, to support speeds of up to 10Gbps using G.gmfast. About two years ago, the successor to G.fast could be seen, from time to time, breaking records and delivering up to 1.8Gbps on a twisted pair over a shortened loop length. A resurgence of…
