Re: BT to offer 100Mbit broadband
 

Wrong...this is a move made by BT since the govt gave them a swift kick about rolling FTTH out, this trial is to see if its viable/profitable for them to roll it out fully, if it works out then there is plans to do a full implementation.

Erm, wrong..

Re: BT to offer 100Mbit broadband
 

@flamingeck: ISTR it was something along the lines that BT said they would invest in a national fibre network if they were allowed to carry other services over it ie TV. The government of the time said No.

@Neptune: Righto, although the OP says FTTH. Even so, FTTP is better than nowt!

Re: BT to offer 100Mbit broadband
 

Apparently “boggits” over at Think Broadband believes this system is based on GPON, which if true would mean it works on a similar principle to how Virgin Medias cable network works, albeit with allot more bandwidth per UBR to play with. Verizon in the US appear to be using the same system, so I have no reason to doubt this.

Whaa? :)

Re: BT to offer 100Mbit broadband
 

Yep, my fault for posting late at night without checking things first.

Looks like BT is going to target new housing developments only. But it's still fibre to homes, lucky those people who will live in those homes.

But, as for mass rollout of fibre to the masses, it ain't going to happen any time soon. Until someone decides to bite the bullet and stump up the 10 billion odd quid to roll fibre out across the country. I doubt BT will stump up the cash unless they can keep and control the fibre network for themselves.

Re: BT to offer 100Mbit broadband
 

gets them in the news.

BTs policy seems to be provide something that has best headline speeds to as little places as possible to keep costs low.

Re: BT to offer 100Mbit broadband
 

It's a trial. They aren't going to spend billions (or tens of billions) of pounds rolling out something nationally before they can ensure it is viable and works well.

The same could be argued about Virgin. The difference being that they have talked publically (to the BBC of all people) about the 50 meg trials, and even said that at some point they are rolling it out nationally. BT have only leaked details to a few IT news sources.

Re: BT to offer 100Mbit broadband
 

Virgin is very different.

Every customer on virgins digital network can get a synch equal to the speed they have paid for so every 20meg customer gst a 20meg synch on the modem.

With BT the 'MAJORITY' of customers do not get the advertised synch speeds only around a quarter can get 8meg on adsl1 and it will be single figures who are able to get close to 24meg infact under 5%. To me thats a large difference.

Now I know virgin have traffic management (BT do also tho) but at least with virgin customers can expect to hit their max speed at some point during the day even if its at 4am whilst if you on adsl and synch below the max speed you will never ever download at max speed because your line is incapable.

As to this trial BT are not going to be doing a national rollout, the shareholders have made this clear and ofcom are sending out noises they wont push for a rollout so the only way BT are doing fiber is if someone subsidises it aka the government.

BTs 21CN will upgrade the dslams to support adsl2+ 24mbit speeds, this will benefit the already lucky few with short lines meaning a higher headline speed for a minority of customers exactly as I said. BT are doing nothing in 21CN to improve things for long lines, they not even replacing ADSL1 with ADSL2, ADSL2 was designed with long lines in mind. (ADSL2 and ADSL2+ are different).

In addition it looks like they removing their fixed 512kbit, 1mbit, 2mbit products from wholesale putting everyone into a one speed fits all product priced the same regardless of synch speed you get, ignoring the fact some lines are unstable on rate adaptive adsl and need fixed speeds to be stable. Cable has its problems but believe me adsl is far worse in equality.

The grass may seem greener but it isnt always the case.

I am speaking as someone who has used cable and adsl in recent years, I was in one of ntls worst areas analogue only services and congested ubr's dispite this I have found adsl to be a significantly worse experience in both performance and stability.

Re: BT to offer 100Mbit broadband
 

This trial is not using ADSL, so any comparison with ADSL is irrelevant.

Re: BT to offer 100Mbit broadband
 

Didnt ntl trial FTTH a while back, im assuming it didnt turn out well as it never made it out of trials? will BT have a more cost effective solution?

Re: BT to offer 100Mbit broadband
 

Unlike BT, Virgin doesn't need FTTH to obtain high speeds.

Unlike BT, Virgins fibre network runs up to very close to the property already within a few hundred metres as opposed to a couple of km in the case of BT.

Theoretically you can speeds of 250mbs over copper.

This is just a headline winning exercise by BT after Virgin announced their "achievable to most customers" 50mbs, BT have decided to announce their "achievable to 2 cats and a dog in ebbsfleet" 100mbs.

Yep, Dolphin Square:

Re: BT to offer 100Mbit broadband
 

yeh, thought it was dolphin square. would be nice to see FTTH as it can offer greater services than current broadband technologies. but i cant see it coming any time soon :(

Any ideas on which ftth system they will be using?

Re: BT to offer 100Mbit broadband
 

BT, unlike Virgin (apparently) don't announce products until *after* they have been successfully tried them. They haven't officially announced 100 meg. 50 Meg was announced by Virgin while they were still trialling it.
