WiFi is one of the main ways with which tablets communicate, the other being Bluetooth. WiFi is essential for going on the internet, downloading apps, watching streaming videos and many other things, such as video chatting and online games. WiFi can even be used on the move using mobile hotspots and internet.
WiFi is therefore essential to any tablet, and the Samsung Galaxy Tab E Lite Kids naturally comes with it. The WiFi can be turned on or off as desired (when away from charging points and WiFi connections, it makes sense to turn it off to prolong battery life). With its WiFi, the tablet can also communicate locally with other WiFi enabled devices without actually having to connect to a WiFi network.
