Bluetooth Introduction

We often use Bluetooth wireless headphones, and let the phone plays music through the car via Bluetooth. So what is Bluetooth?

History of Bluetooth

The Bluetooth standard was originally conceived by Dr. Jaap Haartsen at Ericsson back in 1994. At the time, it was designed to replace RS-232 telecommunication cables, by using short-range UHF radio waves between 2.4 and 2.485 GHz. Bluetooth has always been designed as a much shorter range and lower power alternative.

In 1998 the Bluetooth Special Interest Group (SIG) was formed, which to this day publishes and promotes the standard and its subsequent revisions. Bluetooth SIG initially only included Ericsson, IBM, Intel, Nokia, and Toshiba, but reached 4,000 members by the end of its first year. The latest version is Bluetooth 5.

Bluetooth Features

Bluetooth is designed to allow low wireless bandwidth communication to make it easier to use and therefore those new to wireless can use them.

The Bluetooth definition provides otherwise radio classes allow for the transmission of up to 100 meters by increasing the power of the radio. The Bluetooth technology is not limited to eye transmission because it uses directional waves capable of transmitting through multiple bans.

Bluetooth is the standard connection of the wireless, which means it enables communication on other devices and, such as cell phones, computers, digital cameras, and other types of electrical equipment. The bluetooth definition describes the radio program and the “stack” of the protocol layers and profiles. The top layer is the application layer, while the lowest layer is the radio.

Bluetooth also provides a solid, authentic link that standard operating conditions do not exist interrupted by interference from other signals which operate on the same frequency band.

Also known for its global performance, Bluetooth the radio operates on a 2.4 GHz frequency band, i.e. is unlicensed and available in any type of the world’s radio program. It doesn’t matter where you are in the world, you rely on Bluetooth to work.

Security is also important. Delivery has improved security measures, Bluetooth ensures high-quality security. So, authenticity will do prevent unauthorized access to important information as well as make it very difficult to listen.

Typical applications of Bluetooth

Bluetooth definition eliminates the need for cables by providing a small form factor, low pay for a wireless solution that will connect computers cell phones, and other electronic devices. Bluetooth and allows users to connect multiple distances of devices quickly and easily and increases communication skills.

Bluetooth has been applied to the following products:

Bluetooth headset, Bluetooth audio, smart phone, Bluetooth keyboard, Bluetooth mouse, tablet PC, smart TV, laptop, desktop computer, interconnection between various short distance devices, such as printer, etc. There are also the Internet of Things, Smart Home, and Telematics, which have been very hot in recent years.
