Bluetooth

Bluetooth is a proprietary open wireless technology exchangeable for exchanging entropy over short distances (using short-wavelength radio transmissions in the philosophical system band from 24002480 megacycle per second) from fixed and mobile devices, creating person-to-person area earningss (PANs) with eminent levels of security. Created by telecoms vendor Ericsson in 1994,[1] it was sooner conceived as a wireless alternative to RS-232 data cables. It whoremonger connect some(prenominal) devices, overcoming problems of synchronization. Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 16,000 division companies in the areas of telecommunication, computing, networking, and consumer electronics.[2] The SIG oversees the development of the specification, manages the qualification program, and protects the trademarks.[3] To be marketed as a Bluetooth device, it essential be qualified to standards defined by the SIG.

Futhark runes (Hagall) (?) and (Bjarkan) (?), Haral! ds initials. Implementation Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 bands (1 MHz each; centered from 2402 to 2480 MHz) in the range 2,4002,483.5 MHz (allowing for care bands). This range is in the globally unlicensed Industrial, Scientific and health check (ISM) 2.4 GHz short radio frequency band.
