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 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).

Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference.
The user's face is scanned by the headset during setup to generate a persona—a realistic avatar used by OS features. One such feature is "EyeSight", an outward-facing screen which displays the eyes of the user's persona. Its eyes appear dimmed when in AR and obscured when in full immersion to indicate the user's environmental awareness.
A bluetooth radio module with built-in antenna (left) Any communication technology sending digital data wirelessly involves a modem. This includes direct broadcast satellite, WiFi, WiMax, mobile phones, GPS, Bluetooth and NFC. Modern telecommunications and data networks also make extensive use of radio modems where long distance data links are ...
