When do i use wifi

One is called the modem and the other is called the router. Here is the differentiating factor between the I nternet and WiFi. If Internet allows you to access information from other computers across the world using a specific language protocol , then WiFi is just a way of connecting to that wire in your living room wall and out to the Internet, wirelessly.

Okay, imagine a radio tower, broadcasting the latest 40 pop songs to cars all over the city. Now, imagine that radio tower is the size of a lunch box and each car is a different WiFi enabled device iPad, iPhone, Mac, etc living in your house. Now imagine that instead of the same 40 songs over and over again, that lunchbox router is broadcasting the Internet to your devices.

When you see those WiFi bars on your iPad in the top-left corner of the screen, your iPad is totally jamming out to the pop songs that are the Internet - but is it really?

Well, not necessarily. The radio tower that is broadcasting its network throughout your home will not stop broadcasting its signal if the internet is no longer being fed to it. For example: you go onto Safari on your iPad with connected WiFi and you type in facebook.

Then, you get an error message! This concept is called geo-fencing. Like a regular fences, geo-fences encircle an area. What does geolocation have to do with WiFi?

Geolocation is fairly complex, and when using various satellite services to calculate your location, it can be fairly battery intensive. To combat this, manufacturers have turned to cell towers and WiFi access points to help get a rough location without having to listen for all those satellites. Nagy loves this feature, and who can blame him? Ironically, one of the best ways to get your location is through identification of the Wireless Access Points around you, but to do so, your WiFi has to be turned on.

Luckily, Google has a little trick it built into our smartphones and tablets. The battery impact is low, but sometimes has unintended consequences.

To use it, either the company that built your phone has to add that functionality or you have to install and configure a third-party app. Activities such as streaming audio and video benefit from the lower latency that is associated with using a Wi-Fi hotspot. If you need to download large files or stream media to your smartphone in a hurry, it is much better to do so via Wi-Fi. In situations where you have access to free Wi-Fi -- such as at home, work or some cafes, airports and hotels -- it makes more sense to use this method to connect your phone to the Internet.

For example, if you have an uncapped Internet connection at home, you can connect your phone to the router via Wi-Fi and download all necessary updates or software without having to pay your mobile provider.

There are also applications available for smartphones that enable you to make voice calls using a Wi-Fi connection; this can save you money if both you and the recipient use the app. Battery life is extremely important for smartphones, as you will not be able to connect to the Internet or use certain functions such as the camera flash if your battery is too low.

In the same cellular settings, you will see a toggle button against each application. You can also see the data usage for each app. If a certain app is using a lot of data, you can simply turn that off. That way, even when data usage is turned on, the app will not use it. You can tell from the screen if the phone is using Wifi or LTE.

On the top of your screen, if you see the fan symbol, that means that the phone is using Wifi. If you have both types of connection turned on, it could frequently interchange, depending on the strength of the signal from the router. So you should get on top with what exactly is being used every time you unlock your phone.

On some phones that consume both at the same time, it can be difficult to keep track. You might only see the Wi-fi connected at the top of your screen.
