G.FAST
« on: April 02, 2015, 07:29:14 PM »

Damn ..... tried to copy some notes from a BT publication ........ didn't work.

Basically, this summer BT plan to trial G.FAST on approx. 4,000 homes from Gosforth and Huntingdon. If successful, a limited roll-out will start in 2016, with a large-scale roll out in 2017.  :)

That rules me out as my loop length is greater than 500 meters  ;

They could just enable 30MHz profiles now with g.inp and job done? :)

I don't think it does, I think G.Fast basically puts smaller boxes further out into the network, so one will almost certainly be closer to you.

Read the page you linked to, specifically deployment scenarios!

PS. Great news, but why couldn't it be my area.

Ronski is correct, as that was also in the blurb I was trying to paste.

Essentially FTTDP (fibre to the distribution point)?  :-\

There's a very nice pole around 40m from my house where one could be sited  :fingers:

Overhead DPs are readily identifiable, but how does one do the same when the wires are underground? I wouldn't have the faintest where my DP was.

BS are BT actually going to be deploying new boxes nearer homes? as there was an article not long ago suggesting they will do it on the cheap by deploying it from cabinets.

Wasn't that something Saffy wrote about on TBB? If yes, then I wouldn't take it as a definite fact, in any shape or form.  :-X

Ah ha! Ideas and plans change all the time. Personally, I only believe what I can see with my own eyes.  ;)

This part concerns me as RFI is the biggest downside for broadband end-users.

[1] This spectrum overlaps with the FM broadcast band between 87.5 and 108 MHz, as well as various military and government radio services. To limit interference to those radio services, the ITU-T G.9700 recommendation, also called G.fast-psd, specifies a set of tools to shape the power spectral density of the transmit signal;[8] G.9701, codenamed G.fast-phy, is the G.fast physical layer specification.[6][15] To enable co-existence with ADSL2 and the various VDSL2 profiles, the start frequency can be set to 2.2, 8.5, 17.664, or 30 MHz, respectively.[1]
