ADSL2+ or FTTC?
Will the cabinets have FTTC at all or is it just ADSL2+ technology?
Good Morning Chen,
Thanks for writing in to us.
All cabinets deployed under our programme will be FTTC (VDSL) technology.
Will there be any new cabinets/exchanges built to serve rural villages? If not I think things will be the same since most people will only see a 3mb increase of speed.
We are conscious that FTTC technology will not necessarily provide Superfast speeds to all premises and to that end, we are looking at other technologies that will push higher speeds further out into the infrastructure.
With regard to your comments about those in Rural areas only getting a 3Mb/s uplift, FTTC will normally provide circa 80Mb/s very close to the cabinet and then depending upon line quality etc. speeds will drop off with distance. Looking at various graphs that are theoretical models, Superfast (>24Mb/s) is achievable up to circa 1400m and then continues to drop off with distance from there. Each individual line is slightly different and these numbers are theoretical, but at 2Km, you are still getting very reasonable speeds.
I am about 500m from the nearest cabinet yet I have 35db line attenuation which is relative to 2500m.
I currently get 6mb speed on ADSL max.
When VDSL or VDSL2 is introduced I will get no line speed increase. I will only see an increase if I have a ADSL2+ line and at best I will only see a modest increase. Perhaps 3-5 mb.
I think it may be worth while if ON Lincolnshire campaign paid some attention to the old infrastructure. As I understand it FTTC (Fibre to Cabinet) still uses the copper wire that connects the client to the cabinet.
Most telephone posts where put up when the Internet didn't even exist. BT will not cover these costs though. I think residents would actually pay a little to sort this mess out though because the speed increases would double even without upgrading to better types of DSL.
But I know what your going to suggest next.
You mention other technologies. Well there is nothing wrong with 4G LTE/WIMAX but the cost is one big issue in comparison to the cost of services down a Fibre line.
Broadband can cost as little as 1.75 pounds with talktalk on a VDSL/ADSL2+ line however on a 4G WIMAX set up your looking at 27.50 pounds with Quickline Communications. Then you also need to consider that Quickline Communications/AB Internet both charge up to 195 pounds for installation costs for the necessary hardware to be installed in a clients home.
The conclusion is this. Rural customers will still be paying 15 times more for broadband than urban customers. It would be better to sort out the old infrastructure to reduce line attenuation (length/resistance) and maximize the potential for the technologies which provide best value for money.
I'm sorry but I am not getting my hopes up.
Good Morning Cheng,
There is no doubt in our minds that providing a fibre connection from the Exchange to the end user is by far the best solution.
However, the cost of providing fibre to the premises (FTTP) is much higher than than fibre to the cabinet (FTTC) and is a cost that the UK cannot afford. On that basis, we are forced into a compromise position which is FTTC.
I would accept that the connection and running costs of a Fixed Wireless solution can be more expensive than a FTTC line, but unfortunately, where line length is excessive, FTTC starts to fail and FTTP isn't an option because of cost.
We are currently looking at fibre to the remote node FTTRN as a possible solution along with non-line of sight fixed wireless. All emerging technologies are currently being assessed.
With regard to living circa 500m from the cabinet, unless you have a significant external line quality issue, or an internal wiring issue, at 500m from the cabinet, you should be getting well in excess of 'Superfast' speeds (>24Mb/s).
