*’blue-tooth’ is a ‘wire-less technology standard’ for exchanging ‘data’ over ‘short distances’*

.

(‘bluetooth’ uses ‘short-wavelength UHF radio waves’ in the ‘ISM band’ from 2.4 to 2.485 GHz) from ‘fixed’ + ‘mobile devices’)

(…building ‘personal area networks’ (PANs))

(invented by telecom vendor ‘ericsson’ in 1994, it was originally conceived as a wireless alternative to RS-232 data cables)

(it can connect several devices, overcoming problems of ‘synchronization’)

.

(‘bluetooth’ is managed by the ‘bluetooth special interest group’ (‘SIG’), which has more than 25,000 member[companies in the areas of…]

‘telecommunication’

‘computing’

‘networking’

‘consumer electronics’

.

(the ‘IEEE’ standardized ‘bluetooth’ as IEEE 802.15.1)
(but no longer maintains the standard)

.

(the ‘bluetooth SIG’…)

*oversees development of the specification*

*manages the ‘qualification program’*

*protects the ‘trademarks’*

.

(a manufacturer must make a device meet ‘bluetooth SIG standards’ to market it as a ‘bluetooth device’)

(a network of patents apply to the technology, which are licensed to individual ‘qualifying devices’)
