Airplane mode: When activated, this mode suspends the device’s radio-frequency (RF)signal transmission technologies (i.e., Bluetooth, telephony and Wi-Fi), effectively disabling all analog voice, and digital data services.
Wi-Fi: Wi-Fi is a family of wireless network protocols, which are commonly used for local area networking of devices and internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world.
Bluetooth: Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones.
Personal Hotspots: A private hotspot, often called tethering, may be configured on a smartphone or tablet that has a network data plan, to allow Internet access to other devices via Bluetooth pairing.
