Data tethering is the process of data sharing with other devices using WiFi, Bluetooth, or a USB cable. 

Tethering is the simplest way to access cellular data when you struggle to find a stable internet. It is an essential tool to share a mobile internet connection with laptops, tablets, and smartphones. It offers internet access via Bluetooth, USB, and WiFi. This is especially useful for digital nomads who need to work from remote locations where public Wi-Fi is unavailable.

This article is a detailed guide about tethering, how it works, and setup in your device. 

What is data tethering?

Data tethering is the process that turns your device into a modem to share data with other devices. The other devices include smartphones, laptops, tablets, and iPads. Like a hotspot, your device acts as a portable internet access point and allows mobile data sharing. 

Hotspot and tethering both offer internet sharing, but these are not the same. A hotspot is the wireless WiFi that allows 5 to 10 devices to connect at a time. Tethering is generally data sharing via WiFi, Bluetooth, or USB. 

How does tethering work?

Tethering takes your mobile data connection and shares it with other devices via WiFi, Bluetooth, or USB. When you turn it on and create the WiFi hotspot, it appears in the list of paired devices. 

Tethering works when the device is unable to establish an internet connection. Then the device accesses the data connection from the tethering devices. Manufacturers and operating systems are named different in devices, like some call this internet sharing. 

Methods of Tethering

Mobile phones tether data in different ways. Let's find the latest and best method. 

WiFi Tethering

In WiFi tethering, your smartphone acts as a portable WiFi hotspot and provides the internet to other devices. You need to enable the Mobile Hotspot or Personal Hotspot to connect other devices to the newly created WiFi. It drains more battery, but is convenient to access. 

Bluetooth Tethering

Bluetooth tethering shares data with other devices via Bluetooth. Enable Bluetooth on both devices and turn on Bluetooth tethering. But it provides a slower data connection, and the network range is also shorter. Compared to WiFi tethering, it uses less battery. 

USB Tethering

This method works by connecting the device to your phone via USB. It provides fast connections, eliminating wireless interference. Compared to other methods, it is not flexible and offers a single connection at a time.
