It's really cheap to just hang a box on an existing remote terminal. "We're rolling out those side pods on the cabinets a quite a place now we have the production hardware, we have the production firmware and we're building a footprint quite quickly now," said Clive Seeley on the quarterly call. "The indications are that the performance of the product over the new equipment is pretty much spot on what we had predicted from the labs in the earlier few trials and I am very pleased with that. So I'm very pleased with where we stand right now on G.fast."
They are on target for 150,000 or so homes passed in the next couple of months and a fast ramp towards the 10M they've promised for 2020. BT is running G.halffast, with a target of ?300 down, ?30 up at three hundred meters. It would be impressive if they hit that; the results I've seen elsewhere are 10%-20% lower. The results at 100 meters - the plan before the beancounters jumped in - will probably be 500-800 megabits split between upstream and downstream. The early trials of G.fast have shown 5%-15% of the lines do not reach the expected speeds. BT and everyone else in the industry are scrambling to find and fix the problems.
The more interesting question is whether Huawei and Nokia have delivered the external vectoring boxes expected about six months ago.
