We all use WiFi on a near-daily basis – it’s essential for getting us online and keeping data costs down. But how many of us could explain the ins and outs of how WiFi actually works?
The Basics of WiFi
WiFi in the average home or business is essentially a system whereby a device receives and transmits a wireless signal. This is usually done by a router. The signal is received from a provider and then transmitted from the router to all the devices within the property, whether smartphones, laptops or even smart televisions.
To set up WiFi at home, you will need a router and a provider. You’ll also need your admin rights so that you can set up a network and associated network security key. This security key can then be shared with anyone who you don’t mind having access to your WiFi signal.
What about the costs?
WiFi is free in some places, such as restaurants and libraries, but in most homes and private offices, it’s something we need to pay for.
There are many reasons why it’s preferable to use WiFi at home rather than mobile internet. The most important of these is that there isn’t usually a limit on how much you can download via WiFi, so it’s fine to download films or stream programmes which would be costly via 4G or 5G mobile signal. Downloading the same amount while using mobile data would be much more costly, according to consumer experts Uswitch
Phones, televisions and other devices can all share a WiFi network. Also, WiFi call buttons can be a really great use of a WiFi network, facilitating a one-touch call system to get in contact with someone else, whether for a service such as housekeeping or emergency assistance. Specialist suppliers such as www.dinggly.com/products/wireless-call-buttons/ offer a wide range of WiFi call buttons and can set a system up easily.
The only real downside of WiFi is that the area it covers is limited – it will usually only cover the area inside your home or office.
