Bluetooth is a wireless technology trendy used for changing data among fixed and cell devices over quick distances using uhf radio waves in the business, scientific and clinical radio bands, from 2. 402 ghz to two. 480 ghz, and building non-public place networks (pans). It turned into at the start conceived as a wireless opportunity to rs-232 statistics cables. Bluetooth is controlled through the bluetooth special hobby group (sig), which has more than 35,000 member agencies in the regions of telecommunication, computing, networking, and patron electronics. The ieee standardized bluetooth as ieee 802. 15. 1, but no longer maintains the usual.
The bluetooth sig oversees development of the specification, manages the qualification application, and protects the trademarks. A producer should meet bluetooth sig standards to market it as a bluetooth device. A community of patents practice to the era, which might be licensed to character qualifying devices. As of 2009, bluetooth integrated circuit chips deliver approximately 920 million devices annually. The improvement of the "quick-hyperlink" radio technology, later named bluetooth, was initiated in 1989 by means of nils rydbeck, cto at ericsson cellular in lund, sweden. The reason turned into to develop wireless headsets, consistent with two inventions by johan ullman, se 8902098-6, issued 1989-06-12 and se 9202239, issued 1992-07-24. Nils rydbeck tasked tord wingren with specifying and dutchman jaap haartsen and sven mattisson with developing. Each have been operating for ericsson in lund. In 1990, jaap haartsen was nominated by using the european patent office for the european inventor award. From 1997 Orjan johansson have become the task chief and propelled the technology and standardization. In 1997, adalio sanchez, then head of ibm thinkpad product r&d, approached nils rydbeck approximately collaborating on integrating a mobile cellphone into a thinkpad pocket book. The two assigned engineers from ericsson and ibm to examine the concept. The realization become that power intake on cellular phone technology at that time was too excessive to permit viable integration right into a notebook and nevertheless attain good enough battery lifestyles.
