ADSL broadband is the technology that works through our telephone lines. There are many other types of broadband including mobile broadband, fibre optic broadband, and satellite broadband. The most widely available broadband on the market is ADSL and it is the most compare broadband deals popular.
This article will take a look at what ADSL is and what the costs involved are down to the hidden, and not always very well advertised, additional expenses that you may have to pay.
What is ADSL broadband?
ADSL broadband is the broadband that passes through our telephone lines. We plug in a router to our BT telephone point and then we receive internet over the copper cables of the BT infrastructure. The limitation of the technology is that the distance from the telephone exchange dramatically impacts the speed that we’ll get in our homes at the end.
It may be that if we are a long way from the telephone exchange, we struggle to get any sort of level of connectivity at all. In comparison, if we are within 200 meters of the exchange we may get over 20Mbps and have speeds comparable to fibre optic broadband.
ADSL technology is set up using a Wi-Fi router or modem plugged in through microfilters into our telephone line. The microfilters are there to split the voice and data components of the line to prevent interference from voice devices. Therefore, you should have microfilters plugged in to every telephone port that has anything plugged in off it such as burglar alarms, faxes, or televisions.
The technology itself is some of the cheapest out there with broadband packages starting from a few pounds per month. You will, however, have to get a landline.
The Landline Costs
Because you have to have an active line for ADSL, you will have to pay landline cost. Landline rental normally amounts to around £12 to £15.50 a month and different providers offer different deals. With some providers you can receive three, six, or even 12 months free landline rental depending on the size of the package you take. The more services you take from the provider, such as is the case with a bundle, the more likely you are to receive additional discounts and often these are on the landline rental.
