What is the difference between 3g and wifi

You can obtain an internet signal from the mobile-phone network, rather than the WiFi network, by using a dongle. This is a small device about the size of a key ring, which plugs into your laptop. It acts as a kind of aerial that allows you to connect to the internet by picking up the signal from the mobile telephone network.

You can also 'pair' your laptop with your phone and use it as a 'personal hotspot', which means you can use the 4G from your phone to access the internet on your computer.

To do this go into your phone's settings, look for the term 'personal hotspot' and turn it on. Then click on your WiFi icon on your laptop and select your phone from the drop-down list. If it asks for a passcode, you will find this in the personal hotspot settings on your phone.

Both Wi-Fi and 3G are advanced wireless communication technologies offering a wide range of features and advantages to individuals who need Internet connectivity at any given time.

Wi-Fi access is controlled by a Wi-Fi router located at a distance from an access point while 3G is completely controlled and provided by a service provider.

Wi-Fi offers speeds of about Mbps while 3G delivers speeds about kbps. Wi-Fi signals can be received if the user is present within the range of the router situated at a hotspot. Wi-Fi can be easily installed by anyone by setting up a wireless LAN on a computer which has a wireless adapter installed while 3G wireless WAN can only be installed by carrier companies.

WiFi networks are fairly common, as most coffee shops, restaurants, libraries, and bookstores have either free hotspots or will give out a password to paying customers. If you have access to WiFi, it's generally best to use it. Using WiFi is usually faster than cellular and it doesn't use your cellular data plan, which can save money.

A few final notes about cellular devices that can provide WiFi hotspots, they do this by translating their cellular connection into a WiFi network. The practical purpose is to allow the many WiFi-only mobile devices, such as some iPads and e-readers, internet access wherever you can set up your 4G device. Though it makes WiFi access more mobile, the function typically creates a hotspot, allowing public access to not just the Internet but any device on the network, and is only as fast as the 3 or 4G connection of the device creating the network.
