What is Broadband – FAQs
Is broadband and Wi-Fi the same thing?
Broadband and Wi-Fi are related but not the same thing. Here’s a quick breakdown:
- Broadband: This refers to the high-speed internet connection provided by your Internet Service Provider (ISP). It can be delivered through various means such as DSL, fibre optics, or cable. Essentially, broadband is the pipeline that brings the internet to your home.
- Wi-Fi: This is a technology that allows devices to connect to the internet wirelessly. Your router uses Wi-Fi to broadcast the internet signal from your broadband connection to your devices like smartphones, laptops, and tablets.
So, while broadband is the actual internet connection, Wi-Fi is the method used to access that connection wirelessly.
Can I get Wi-Fi without broadband?
Yes, you can get Wi-Fi without a traditional broadband connection! Here are some alternative methods:
- Mobile Hotspot: Use your smartphone’s data plan to create a Wi-Fi hotspot. This is a convenient option if you have a good mobile data plan.
- Tethering: Connect your smartphone or tablet to your computer via USB, Bluetooth, or Wi-Fi to share its internet connection.
- Public Wi-Fi: Many public places like libraries, coffee shops, and restaurants offer free Wi-Fi. Just be careful about security when using these networks.
- Wi-Fi USB Dongle: These devices use a SIM card to provide internet access and can be plugged into your computer’s USB port.
- Portable Wi-Fi Router: Similar to a mobile hotspot, these routers use a SIM card to create a Wi-Fi network that multiple devices can connect to.
How does broadband connect to your house?
Broadband can connect to your house in a few different ways, depending on the type of connection available in your area:
- ADSL (Asymmetric Digital Subscriber Line): This uses existing copper telephone lines to deliver internet service. The connection runs from the local telephone exchange to a street-level cabinet and then to your house via copper cables.
- FTTC (Fibre to the Cabinet): This is a hybrid solution where a fibre optic cable runs from the local exchange to a street cabinet, and then copper cables connect the cabinet to your house. This setup offers faster speeds than ADSL.
- FTTP (Fibre to the Premises): This is the fastest option, where a fibre optic cable runs directly from the exchange to your house, bypassing any copper cables. An engineer will typically install a small junction box on the outside of your house and run a fibre cable inside to a wall-mounted unit where your router connects.
Do I need a phone line for broadband?
Whether you need a phone line for broadband depends on the type of broadband connection you choose:
- ADSL and FTTC (Fibre to the Cabinet): These types of broadband typically require a phone line because they use the same infrastructure as traditional telephone lines.
