Bluetooth technology allows wireless communication between electronic devices within a short distance. Devices need a Bluetooth chipset, which includes a wireless transceiver and software. Bluetooth ASICs are customizable and use less power than chipsets. Bluetooth was developed by Ericsson in 1994 and is managed by a special interest group.
Bluetooth® technology allows electronic devices to communicate with each other wirelessly over short distances. For devices to use Bluetooth® technology, they must be equipped with a Bluetooth® chipset. Using this technology, computers, cameras, telephones, stereo systems and printers, among other devices, work together without the need for cables.
Bluetooth® devices come with a Bluetooth® chipset installed. A Bluetooth® chipset is made up of computer chips that integrate Bluetooth® technology into an electronic device. While there are several components that may be included in a Bluetooth® chipset, many chipsets are integrated on a chip.
One of the most important components in a Bluetooth® chipset is the wireless transceiver, which allows devices to send and receive information over radio waves. Another component of a Bluetooth® chipset allows Bluetooth® software to run on a particular device. It’s impractical to install new software on some types of electronics, so they come with the software already installed and enabled.
Many devices communicate using radio waves. A Bluetooth® chipset allows an electronic device to communicate with other devices using radio waves designed to travel only a very short distance, called a person’s personal network. This space has a radius of approximately 33 feet (10 m). Televisions and cell phones also send and receive information using radio waves, although they use radio waves differently than Bluetooth® because the waves are designed to travel great distances.
Technological developments have opened up the possibility of using Application Specific Integrated Circuits (ASICs) instead of Bluetooth® chipsets. While this technology is not readily available, many engineers prefer it because it is customizable. ASICs take up less space than a chipset because they can be specially designed to fit that particular device. Additionally, a Bluetooth® ASIC uses less power than a Bluetooth® chipset.
Bluetooth® technologies became more sophisticated from the 1990s to the 2000s and 2010s. In 1994, engineers at the Swedish company Ericsson expanded on the technology introduced in the 1940s to create the wireless technology currently used in Bluetooth® devices. Soon after, a number of companies created the special interest group (SIG) they called Bluetooth®. Bluetooth® itself is not a company, but is a technology shared by SIG members, who manage and develop it collaboratively.
