Connection sharing on Android: how does it work?

Android like iOS allows you to easily transform your smartphone into a WiFi, Bluetooth and USB router. We can then use the 3G / 4G mobile data as internet connection and share it with the devices of your choice. WiFi, Bluetooth, USB … each connection mode has its particularities, advantages and disadvantages that should be taken into account depending on the situation.

The advantage of this connection mode is its simplicity. The downside is that you can't really control what connects to it. Which can lead to excessive data consumption.

The Bluetooth connection sharingbuilds on the specifics of this technology. The Bluetooth signal gate is relatively short, which limits the risk of unwanted connections. To connect your Bluetooth network, you must also pair the devices. In general, only one device can be connected via Bluetooth.

Theconnection sharing via USB changes the behavior of the USB-C port on your smartphone. So when you connect your smartphone to your computer, the latter detects a new network card and installs drivers – at least during the first connection. Once the configuration is done, the connection can be established. This method is the most secure, since it is impossible to connect via USB without your knowledge – and the fact that there is no wireless network limits the risk of hacking.

Note : Connection sharing via USB is only compatible with Windows and Linux PCs.
