However Ericsson released the R520m in Quarter 1 of 2001, making the R520m the first ever commercially available Bluetooth phone. In parallel, IBM introduced the IBM ThinkPad A30 in October 2001 which was the first notebook with integrated Bluetooth. Bluetooth's early incorporation into consumer electronics products continued at Vosi Technologies in Costa Mesa, California, initially overseen by founding members Bejan Amini and Tom Davidson. Even the maximum power output of Class 1 is a lower level than the lowest-powered mobile phones. UMTS and W-CDMA output 250 mW, GSM1800/1900 outputs 1000 mW, and GSM850/900 outputs 2000 mW. The Bluetooth Innovation World Cup, a marketing initiative of the Bluetooth Special Interest Group (SIG), was an international competition that encouraged the development of innovations for applications leveraging Bluetooth technology in sports, fitness and health care products. The IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains the standard. The Bluetooth SIG oversees the development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device. A network of patents applies to the technology, which is licensed to individual qualifying devices. This is in the globally unlicensed (but not unregulated) industrial, scientific and medical (ISM) 2.4 GHz short-range radio frequency band. Bluetooth uses a radio technology called frequency-hopping spread spectrum. Bluetooth divides transmitted data into packets, and transmits each packet on one of 79 designated Bluetooth channels. Each channel has a bandwidth of 1 MHz. Packets may be 1, 3, or 5 slots long, but in all cases, the master's transmission begins in even slots and the slave's in odd slots. The above excludes Bluetooth Low Energy, introduced in the 4.0 specification, which uses the same spectrum but somewhat differently. A master BR/EDR Bluetooth device can communicate with a maximum of seven devices in a piconet (an ad hoc computer network using Bluetooth technology), though not all devices reach this maximum.

The Bluetooth® brand is globally recognizable with up to 92% consumer awareness*. This is why so many companies use the Bluetooth word mark and logo on their… The Bluetooth Special Interest Group (SIG) owns the Bluetooth word mark, figure mark and combination mark (collectively, the Bluetooth trademarks), and protects the Bluetooth trademarks through the brand enforcement program. In order for a company to use the trademarks, two things must happen: 1) a company must be a member of the Bluetooth SIG and 2) the goods offered must have completed the Bluetooth Qualification Process. The Bluetooth® brand is globally recognizable with up to 92% consumer awareness*. This is why so many companies use the Bluetooth word mark and logo on their packaging and advertising, and throughout their marketing. When consumers see the Bluetooth brand they know the product is trusted and will work with any of the other Bluetooth products they already own. The brand guide contains all the essentials you need to market your Bluetooth product including the color breakdown for print packaging, how to use the logos and other guidelines.

Next to the development of the technology itself, the qualification process is one of the most important aspects of Bluetooth technology, supporting interoperability, conformance to the Bluetooth specifications, and to strengthening the Bluetooth brand. Members of the Bluetooth SIG must complete the qualification and declaration process for their Bluetooth enabled product(s) to demonstrate and declare compliance to the [1]. Any company incorporating Bluetooth wireless technology into products, using the technology to offer goods and services or simply re-branding a product with Bluetooth technology may become a member of the Bluetooth SIG. The Bluetooth Special Interest Group (Bluetooth SIG) is the standards organization that oversees the development of Bluetooth standards and the licensing of the Bluetooth technologies and trademarks to manufacturers. The SIG is a not-for-profit, non-stock corporation founded in September 1998. The SIG is headquartered in Kirkland, Washington, US. The SIG does not make, manufacture or sell Bluetooth-enabled products. Bluetooth technology provides a way to exchange information between wireless devices such as PDAs, laptops, computers, printers and digital cameras via a secure, low-cost, globally available short-range radio frequency band. Originally developed by Ericsson, Bluetooth technology is now used in many different products by many different manufacturers. The SIG owns the Bluetooth word mark, figure mark and combination mark. These trademarks are licensed out for use to companies that are incorporating Bluetooth wireless technology into their products. To become a licensee, a company must become a member of the Bluetooth SIG.

Major Bluetooth Manufacturers - Bluetooth Technology 101 - Tom's ...

From keyboards to headsets to mobile computing, Bluetooth provides the personal wireless network needed to get around without a bunch of cables entangling our lives. Here's a close look at a key technology that empowers our mobile world. Sony, Philips, Samsung, Apple—all of these companies are major presences in the Bluetooth landscape. Bluetooth chipsets are generally manufactured by semiconductor companies, and once qualified/certified, incorporated into modules or end-products by the major technology vendors. That very first Ericsson headset was manufactured by VLSI Technologies, which in turn was bought by Phillips in 1999 and then became a part of the Phillips spinoff, NXP Semiconductors. Original Nokia HDW1 headset, the first Bluetooth headset on the market. Other large manufacturers are:Article continues below ... Broadcom, Mediatek and pretty much every other RF module manufacturer has Bluetooth products to offer. Actually hearing aids with button cell batteries these days can use Bluetooth Smart or to be exact bastardized proprietary version of it by Apple and GN Resound which enables them to have wireless audio streaming from various devices with Bluetooth. Comes with expense of range naturally because hearing aids need to use low power version of it (1,5V doesn't give much choice on this ) Max 10m in ideal conditions.

What Is Bluetooth® Technology? - Intel

www.intel.com

Intel is a founding member of the Bluetooth SIG and has played a pivotal role in the evolution and proliferation of the technology. In fact, it was Intel’s own Jim Kardach who suggested the name Bluetooth in 1997—taking inspiration from the 10th-century king who united Denmark and Norway, Harald “Bluetooth” Gormsson. Let’s take a deep dive into what this technology is, how it’s used, and Intel’s role in its past, present, and future. As one of the most common wireless connectivity standards in the world, Bluetooth technology plays an integral part in everyday life. Let’s take a deep dive into what this technology is, how it’s used, and Intel’s role in its past, present, and future. Bluetooth short-range wireless technology enables two devices to connect directly without requiring supporting network infrastructure such as a wireless router or access point. Today, most PCs feature embedded networking cards with Wi-Fi and Bluetooth functionality. These allow for better performance and coordination across both radio capabilities, helping to prevent interference and ensure adequate data transfer speeds. As a technology leader, Intel has included integrated Bluetooth functionality in Wi-Fi cards since 2011.
