*BLUE-TOOTH PREFERENCES*
*macOS*
.
*’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’)
.
*EXAMPLES* –>
*keyboards*
(portable keyboards)
(apple keyboards)
*apple mouse*
*wireless headphones*
*location stickers*
