Connectivity Guide – Which is right for me?

ADSL

ADSL is the entry product into the broadband market.

It is effectively the same as your home broadband and is usually managed traffic flow to give priority during business hours.

There are no guarantees of service and speeds range from 0.5Mbs to 21Mbs depending on your line quality and distance from your local exchange.

The broadband travels from your building to the exchange down conventional copper wire.

This is the cheapest broadband option available.

Costs typically £35 to £50 per month.*

VDSL

VDSL  is also known as Fibre to the Cabinet (FTTC).

This is the latest update to the ADSL technology where BT have effectively added to the central exchanges in each town with thousands of more local mini exchanges (the new green roadside cabinets you see popping up all over the place).

Historically you had copper connecting your building to the exchange but now the copper length has been reduced to the green boxes which in turn connect to the central exchanges using high speed fibre.

This reduction in the copper line length (to typically less than a kilometre) increases broadband speeds to up to 80Mbs.  Again there are no guarantees of service and this higher speed connectivity is available as a slightly increased costs over ADSL.

Costs typically £45 to £65 per month*

Wireless

Where conventional “broadband” products are not available or have limited performance a “line of sight” wireless solution could be considered.

Following site surveys, ADSL-like broadband is wirelessly transmitted to your building from masts which in turn are connected to the internet.

Like ADSL this has no guarantees or service level agreements and comes in speeds of up to 50Mbs.

Costs typically £50 to £100 per month*

EFM

EFM (Ethernet First Mile) is a synchronous product which results is faster broadband.

ADSL and VDSL are asynchronous which means fast download but slow upload, and as each packet (or piece) of data needs to be verified as received this has the result of “bottle necking” your broadband speed.

EFM being a synchronous product means your upload speed is as fast as your download speed and as such the data verification is faster.  This has the net effect of making the connection “feel” faster than an asynchronous line.

These lines cost more but do have guaranteed service levels and speeds of up 35Mbs.  A 35Mbs EFM line will “feel” faster than a 60Mbs VDSL Line.

Costs typically £200 to £600 per month.*

Leased Line / Leased Line Replacement

A leased line is generally a high speed fibre connection direct from the local exchange to your building.

This can also be achieved using Wireless connectivity for areas that do not yet have commercially viable BT coverage and this is known as Leased Line Replacement.

As copper is removed from the equation, speeds are faster and are guaranteed.  This is a synchronous connection (same speed up and down) resulting in a faster feeling internet.

Speeds of up to 10,000Mbs are available and these lines carry in excess of 99% uptime service level agreements.

Costs typically £400 to £1000 per month*
