BT Group is reportedly working with vendor ADTRAN on a long-term evolution of current G.fast technology, called G.mgfast.

  • After disappointment in earlier G.fast contract awards, ADTRAN looking forward to next leap.
  • New technology forms part of ITU’s programme for new access network research.

The proposed specification is aiming for theoretical broadband speeds over copper in the 5Gbps to 10Gbps range, although lab trials are not currently expected to start before 2019.

The anticipated new standard is exploring the use of a substantially wider band of radio spectrum than is involved in current G.fast standards, which could be deployed over both twisted pair and coax copper lines to achieve aggregated speeds of up to 10Gbps.

G.mgfast appears to feature a number of the existing technology’s limitations, however, with a dramatic drop in potential speeds beyond a relatively short length of copper. Current theoretical research estimates in ideal conditions suggest that, beyond 60 metres, advantages over other G.fast iterations are largely annulled.

G.fast appears to be gaining traction as a relatively quick and cost-effective way to deliver faster connections to end users, but is also showing potential as a complement to fibre, as well as other existing infrastructure.

BT has alluded to the prospect of G.fast supporting mobile backhaul for 5G networks, and it is noteworthy that the use-cases for G.mgfast connectivity outlined by ADTRAN suggest this kind of application.

The anticipated use-case for this new approach is predominantly focused towards backhaul applications for small cells, Wi-Fi infrastructure, and other 106MHz or 212MHz G.fast [distributed power units]. Due to the current absence of vectoring capabilities at these very high frequencies, it will be some time before this new standard… is available as a mainstream access technology for high cross talk twisted pair environments. ” – Ronan Kelly, CTO, APAC and EMEA, ADTRAN.

BT has been toying with more widespread fibre-to-the-distribution point, and G.mgfast could potentially enhance this effort. BT has also undertaken research on XG.FAST, a more advanced development of current G.fast in conjunction with Nokia (BTwatch, #270 and #276).

Other companies linked to the next-generation G.fast research include ASSIA, Broadcom, Huawei Technologies, and Intel. The research is being undertaken under the umbrella of the ITU’s Study Group 15, which is tasked with research on access technologies.
