Bluetooth:

Introduction:

A short-range wireless technology standard called Bluetooth is used to create personal area networks and exchange data over short distances between stationary and mobile devices (PANs). It uses UHF radio waves between 2.402 GHz and 2.48 GHz in the ISM bands. It is mostly used as an alternative to wired connections, to transfer files between adjacent portable devices, and to pair wireless headphones with cell phones and music players. Transmission power in the most popular mode is restricted to 2.5 milliwatts, giving it a fairly short range of up to 10 meters (33 ft).

 

Bluetooth

The Bluetooth Special Interest Group (SIG), which has more than 35,000 members from the telecommunications, computing, networking, and consumer electronics industries, is responsible for managing Bluetooth. Bluetooth was standardized as IEEE 802.15.1, but the IEEE no longer upholds the standard. The Bluetooth SIG is in charge of managing the qualification process, developing the specification, and defending trademarks. To market a product as a Bluetooth device, a manufacturer must adhere to Bluetooth SIG standards.The technology is covered by a network of patents, which are licensed to certain qualifying devices. As of 2009, 920 million Bluetooth integrated circuit chips are shipped annually. In 2017, 3.6 billion Bluetooth devices were sold annually, and it was anticipated that this number will rise by 12% annually going forward. Shipments totaled 4.7 billion units in 2021, with a predicted 9% rise.

 

History:

Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden, started work on developing the "short-link" radio technology, later known as Bluetooth, in 1989. Two innovations by Johan Ullman, SE 8902098-6, issued 1989-06-12 and SE 9202239, issued 1992-07-24, state that the goal was to create wireless headsets. Dutchmen Jaap Haartsen and Sven Mattisson were tasked with developing, and Nils Rydbeck assigned Tord Wingren the responsibility of specifying. They were both employed for Ericsson in Lund. In 1994, the team started working on the principal design, and by 1997, they had a practical solution. As the project's leader starting in 1997, rjan Johansson drove innovation and standardization.

 

Nils Rydbeck was approached in 1997 by Adalio Sanchez, then in charge of IBM ThinkPad product R&D, about working together on incorporating a mobile phone into a ThinkPad computer. The two chose engineers from IBM and Ericsson to investigate the concept. The researchers came to the conclusion that the power consumption of mobile technology at the time was too high to allow for practical integration into a notebook while still achieving a sufficient battery life. Instead, the two businesses decided to achieve the aim by integrating Ericsson's short-link technology on both a ThinkPad laptop and an Ericsson phone.Adalio Sanchez and Nils Rydbeck decided to make the short-link technology an open industry standard in order to give each participant the greatest possible access to the market at the time because neither Ericsson phones nor IBM ThinkPad laptops were the market share leaders in their respective niches. The short-link radio technology was contributed by Ericsson, and the logical layer patents were contributed by IBM. Following Stephen Nachtsheim's recruitment by Adalio Sanchez of IBM, Intel also brought on Toshiba and Nokia. The Bluetooth SIG was established in May 1998 with IBM and Ericsson serving as the founding signatories and a total of five participants: Nokia, Toshiba, IBM, Intel, Ericsson, and Nokia.

 

In 1999, the first Bluetooth gadget was unveiled. At COMDEX, a hands-free mobile headset was recognized with the "Best of show Technology Award." The Ericsson T36 was the first Bluetooth mobile phone, but it wasn't until the T39 model's revision that it finally hit store shelves in 2001. Parallel to this, IBM released the first Bluetooth-integrated laptop, the IBM ThinkPad A30, in October 2001.

 

Bluetooth

Vosi Technologies in Costa Mesa, California, led by founding members Bejan Amini and Tom Davidson, continued the early adoption of Bluetooth into consumer electronics goods. Ivano Stegmenga, a real estate developer, had developed Vosi Technologies, which holds U.S. Patent No. 608507, for interfacing cellular phones with automobile audio systems. At the time, Nokia and Motorola dominated the US cell phone market, leaving Sony/Ericsson with a very small market share. Vosi was unable to publicly announce the intention, integration, and early development of other enabled devices, which were to be the first "Smart Home" internet-connected products, due to continuing discussions for an anticipated licensing arrangement with Motorola commencing in the late 1990s.

 

Vosi required a method for the system to communicate with the other devices in the network without using a wired connection from the vehicle. Since Wi-Fi was not yet widely used or supported in the marketplace, Bluetooth was chosen. The Vosi Cello integrated vehicle system and a few other internet-connected gadgets, like the Vosi Symphony, a tabletop device meant to be networked using Bluetooth, had already started to be developed by Vosi. Vosi announced and disclosed its intention to incorporate Bluetooth in its products through the agreements with Motorola.The introduction of the devices was indefinitely put on hold as a result of a legal dispute that erupted between Vosi and Motorola in the early 2000s. Due to its huge market share at the time, Motorola later adopted it in their products, which started the significant spread of Bluetooth in the general market.

 

Jaap Haartsen received a nomination for the 2012 European Inventor Award from the European Patent Office.
