Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Bluetooth 1.2 allowed for faster speed up to ≈700 kbit/s. Bluetooth 2.0 improved on this for speeds up to 3 Mbit/s. Bluetooth 2.1 improved device pairing speed and security. Bluetooth 3.0 again improved transfer speed up to 24 Mbit/s. In 2010 Bluetooth 4.0 (Low Energy) was released with its main focus being reduced power consumption.
Bluetooth Low Energy ( Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart[ 1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [ 2] aimed at novel applications in the healthcare, fitness, beacons, [ 3] security, and home entertainment industries.

Pairing, sometimes known as bonding, is a process used in computer networking that helps set up an initial linkage between computing devices to allow communications between them. The most common example is used in Bluetooth , where the pairing process is used to link devices like a Bluetooth headset with a mobile phone .
The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation.
Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.
Bluesnarfing is the unauthorized access of information from a wireless device through a Bluetooth connection, often between phones, desktops, laptops, and PDAs ( personal digital assistant ). [ 1] This allows access to calendars, contact lists, emails and text messages, and on some phones, users can copy pictures and private videos.
Windows 11 is a major release of the Windows NT operating system developed by Microsoft that was released in October 2021. Starting with Windows 10, Microsoft described Windows as an "operating system as a service" that would receive ongoing updates to its features and functionality, augmented with the ability for enterprise environments to receive non-critical updates at a slower pace or use ...
