What is Broadband? A guide to broadband and how it works
Broadband is a high-speed internet connection that allows you to surf the internet at top speeds. It is one of the most popular choices of internet connection as it’s extremely quick and enables us to make the most of the internet. The most common internet mediums include copper phone lines and optical fibre. In technical terms, broadband is a wide bandwidth data transmission where all sorts of traffic and signals are transported and interchanged, providing top speeds at the click of a mouse.
Before broadband was around, the internet was only accessible through several dial-up connections. Dial-up is the only non-broadband service available for the internet, but it’s very slow by today’s standards and is generally no longer a popular option.
In fact, fixed broadband is the most popular type of household internet connection in the UK, with 98% of households using this type of connection in 2019.
How does Broadband work?
A Broadband internet service is supplied by an internet service provider (ISP). The service provider supplies the service, the router and if required, arranges for the socket to be installed.
Some ISPs have their own internet infrastructure e.g Sky and Talktalk, however, this is costly and complex, that’s why the majority of ISPs use shareable networks to provide their service, including The Phone Co-op.
Types of Broadband
What is ADSL broadband?
ADSL is a service that is provided using existing BT phone lines. ADSL stands for ‘Asymmetric Digital Subscriber Line’ and it is the most popular type of connection that is widely used across the UK. ADSL broadband works through a fixed-line access network, otherwise known as telephone lines in the street. These are made up of copper wires and exchange a series of digital messages which translates the information you receive. These messages are split into either phone or internet signals using a microfilter, which is a small box that fits into the main BT socket in your home.
ADSL is not as fast as fibre, but it is still a reliable choice. The speed you receive depends on your distance from the telephone exchange, so those who live closer will likely get a faster connection. The age and health of the copper wires providing your connection can also play a part in connection speed.
What is cable broadband?
Cable broadband is a form of internet access which uses the same infrastructure as cable television. Cable uses mostly fibre-optic cables to pass digital signals, unlike an ADSL connection which only uses copper wires. The fibre optical material in the wires provides a secure connection for the signal to travel, resulting in a much more reliable signal and less chance of distortion than ADSL. However, cable is not the same as fibre optic. For the last mile between your local telephone exchange and your home, the cable connection is carried in coaxial cable while fibre optic travels through copper wires. Coaxial cable can carry data faster than copper phone lines, making cable packages generally faster than other options.
A cable connection can also carry audiovisual signals, which is why you can get digital TV services from some cable providers.
What is fibre broadband?
Fibre broadband is a high-speed internet connection that uses fibre optic cables. These cables are quicker at transferring data than standard copper cables used in ADSL; meaning it’s a great choice if you regularly enjoy streaming films and music.
There are two types of fibre broadband connection: FTTC and FTTP.
What is FTTC fibre broadband?
FTTC is otherwise known as superfast broadband. It stands for Fibre To The Cabinet. This type of fibre connection runs through fibre optic cables between your local telephone exchange and the phone cabinet on your street. From there, copper cables carry the connection into your home.
What is FTTP fibre broadband?
FTTP Fibre is an ultrafast connection. It stands for Fibre To The Premises, meaning fibre optic cables run all the way into your home delivering a fast connection with minimal chance of disruption. It can also be known as FTTH (Fibre To The Home). As the name suggests, ultrafast broadband gives you an extremely quick and reliable service but it is not currently available everywhere in the UK, so it’s worth checking if you are eligible for it.
What is mobile broadband?
There are some types of internet services that do not require a fixed-line for installation, for example, mobile broadband. This wireless connection uses mobile phone networks and satellites to transmit a broadband service through an ISP, providing long-range internet access so you can browse the internet using mobile data (3G or 4G networks) or Wi-Fi on your phone. It’s all around us with 64% of UK households using a fixed connection also connecting via mobile broadband whilst at home.
How fast is Broadband?
There is no definite answer to the speed of broadband. What qualifies as broadband is different across the UK, even worldwide. Superfast starts from 30mbps and can go up to 300mbps. Anything higher is considered Ultrafast.
As of 2019, 93% of homes in Great Britain have internet access of at least 2mbps, but most homes can get much higher speeds than this. If you’re not sure what speeds are available in your area, you can easily check here.

How do I get broadband?
Getting broadband installed at home is simple, but first, you should check what internet service providers are available in your area and what types of options are available to you at home.
You can then spend some time comparing deals and prices to find a deal that suits you. Signing up is easy, you follow the sign-up process online and in most cases you’ll be sent a router to simply plug in. Most ISPs will carry out a credit check as part of this process. The installation can still be done safely during the COVID-19 pandemic.
How can I find out what broadband is available in my area?
You can check what is available in your area with our broadband checker. Just by entering your postcode and landline number, we can tell you what options are available to you.
We only use this information to check where your nearest telephone exchange is located, as this determines what services you could expect. In some cases you might live too far away from your telephone exchange for certain types of services, this distance can also affect the speeds you could receive.
What broadband package is right for me?
Which package is right for you depends on personal circumstance, preferences and other several factors. Ultimately you need to spend some time comparing deals and consider price, speed, data limit, extras and bundles. Use our recommendation tool to find the perfect broadband deal for you.

I already have broadband; how can I check my speed?
You can check if you are receiving the speeds advertised by your current provider with a broadband speed test.
My broadband isn't working, what can I do to fix it?
If your service isn’t working or you aren’t getting the speeds you’d expect; it might be down to your internet service provider but there are other factors that could affect this. Always check your router signal, your router might be old and you might need an updated router. It could also be down to the copper wires supplying your home connection, not the broadband speed. If you have checked your speed with a reliable test then contact your internet service provider for further assistance.
