It is a short-range wireless communication technology intended to replace the cables connecting portable of fixed devices while maintaining high levels of security. It allows mobile phones, computers

Bluetooth (IEEE 802.15.1) operates at 2.4 GHz over short ranges (typically 1-100 meters) and was specifically engineered as a cable replacement technology for connecting devices such as mobile phones, computers, and peripherals. It includes security features such as device pairing, 128-bit encryption, and authentication to maintain high levels of security, matching every element of the definition.

WLAN (Wi-Fi) is a medium-to-long range wireless networking standard designed for network access, not as a direct cable replacement for individual device-to-device connections.

InfraRed requires strict line-of-sight alignment between devices and very limited range, and does not broadly support the type of flexible multi-device connectivity described.

RFID is used for object identification and asset tracking using radio waves, not for establishing two-way communication links between devices as a cable replacement.
