Protocols

3g: 3g is where you can connect to an internet server when you are not connected to wif-fi, eg. You are outside in the park and you want to check something on the internet, you can check it without connecting to a home internet server. (WI-FI).

4g: Only some phones can connect to 4g in certain areas because it is an upgrade to 3g but it is still being worked on to make it a lot better than the 3g, in some places you can’t connect to 4g because they haven’t got network where they are so therefore 4g won’t work in some areas but will work in others.

Bluetooth: Bluetooth is a connection where you can send music and pictures and other stuff to another person’s phone for free but you need to be paired to their phone and you also need to be really close to the person you are sending your item.

WI-FI: You can connect to a home internet connection but you need to have their permission and there internet code. Also you need to be a certain distance to it. You could go quite far away until it disconnects from your phone, Laptop, Tablet ect. It is good because you can go on the internet for free but only if you are in the persons house that you are connected to, or just outside if their WI-FI connection is strong enough.
