What type of technology is used when pairing devices such as headsets to a smartphone?

Bluetooth operates in the 2.4 GHz ISM band over short distances (typically up to 10 meters for Class 2 devices) and uses a pairing process that establishes an encrypted link between two devices. It is the industry standard protocol for connecting audio peripherals like headsets to smartphones, governed by the Bluetooth Special Interest Group (SIG). The pairing process involves device discovery, authentication, and bonding to create a trusted connection.

Exchange (Microsoft Exchange) is an email and calendaring server platform used for messaging infrastructure - it is not a wireless communication technology for device pairing.

A locator application uses GPS or network-based positioning to find a device's geographic location and has no role in wirelessly connecting a headset.

Remote wipe is a mobile device management (MDM) security feature that erases data on a lost or stolen device and is unrelated to peripheral pairing.
