Why have wifi on cell phone

Incoming and outgoing calls will be done automatically via Wi-Fi. Wi-Fi calling allows you to speak to people in remote locations. You simply need an internet connection. However, Wi-Fi can have a weaker connection than cellular data. Voice quality can be sacrificed if lots of people are using the Wi-Fi hotspot at the same time. This usually happens in crowded places like shopping centers or stadiums. One drawback of Wi-Fi calling is that it can be subjected to disruptions from your network among other VoIP problems.

These issues are preventable, but you might have echoes or delays if you have a faulty network connection. Video calls made using Wi-Fi can suffer as a result.

For this reason, it might not be the best option for remote employees stuck in airports with an overcrowded Wi-Fi connection.

The emergency services use this data to track your location and route your call to the nearest public safety answering point, or PSAP.

As you can imagine, that can drain your battery fairly quickly. When calculating battery drain there are a lot of variables that one must consider, such as distance from the WAP, signal strength, radio noise in the area, and how much data is being sent and received. Using WiFi rather than cellular for data access can yield a significant savings when it comes to battery life — depending on the circumstances.

The further you are from a cellular tower, the more energy you need for that data signal to be of any use. WiFi access points are typically much closer than cell towers, and can therefore use less power to communicate data than cellular. Of course there are exceptions to this rule, and the observed reality may be significantly different in one situation versus another.

These days we like our phones and tablets to know right where we are. They help us get from point A to point B, and geotag our pictures so we know where we took them years down the road. They also enable our devices to do some pretty snazzy things based on where we are, when we enter an area, or when we leave an area. This concept is called geo-fencing. Just follow these steps: Open up Settings on your device.
