Bluetooth Technology

Bluetooth Logo

Bluetooth technology is a short-range, low-power and low-cost wireless technology that provides strong security, robustness and ease of use in the wireless personal area network space, providing access and applications to single or paired users within a mobile personal environment with ad hoc network connections.

The technology being used for high-speed data transfers, through phones and a host of other applications would soon add a whole new dimension to itself for saving lives. The developer of this technology, Bluetooth Special Interest Group (SIG), is planning to extend the services of this technology to the noble task of saving lives.

Bluetooth is a wireless technology standard for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables.

Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 30,000 member companies in the areas of telecommunication, computing, networking, and 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, and protects the trademarks. A manufacturer must 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.

Background

The development of Bluetooth is as fascinating as the technology itself. It is amazing to know that rights to this technology are not held by a company as such but a special interest group consisting of around 6000 companies, hence the name Bluetooth SIG. These 6000 companies use bluetooth technology in various big and small applications.

The Bluetooth logo is a trademark of the Bluetooth Special Interest Group (SIG). The Bluetooth trademarks (word mark, figure mark and combination mark) are wholly owned by the Bluetooth SIG.

Major Applications

1. Other such application of this high-range new Bluetooth would be in the field of transmitting heavy date content, like video-streaming.

2. High-speed Bluetooth technology will enable wireless video-image sharing from mobile phone video clip to PC or TV, or from a handheld camcorder to a TV, printing files from a mobile phone; synchronizing all the songs on an MP3 player with a PC; sending a PowerPoint presentation wirelessly from a PC to a projector or from one note book to another or transferring movies from PC to home theatre or stereo surround-sound system, hassle free.
