What's Bluetooth technology

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994 it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

What's Bluetooth technology

Bluetooth was Created by Ericsson in 1994, Bluetooth wireless technology was originally conceived as a wireless alternative to RS-232 data cables. Bluetooth technology exchanges data over short distances using radio transmissions. Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. The 2.4 GHz ISM band is available and unlicensed in most countries.

What can Bluetooth do?

Bluetooth technology is a wireless communications system intended to replace the cables connecting many different types of devices, from mobile phones and headsets to heart monitors and medical equipment. Bluetooth technology is simple, secure and everywhere. Bluetooth Specification defines a uniform structure for a wide range of devices to connect and communicate with each other.
Bluetooth Smart is the intelligent, power-friendly version of Bluetooth wireless technology. While the power-efficiency of Bluetooth Smart makes it perfect for devices needing to run off a tiny battery for long periods, the magic of Bluetooth Smart is its ability to work with an application on the smartphone or tablet you already own.

• Connecting the Internet of Things
• Bluetooth technology lets you talk, send vital information, listen to music and much more.
• Bluetooth high speed technology lets you quickly send video, music and other large files between your devices.
• Bluetooth Smart makes it easy for developers and OEMs to create solutions that will work with the billions of Bluetooth enabled products already in the market today.

What Bluetooth Means to us?

As a word, Bluetooth makes our life better!
For consumers, Bluetooth comes down to the Internet of Your Things.
You wake up and go for a run with a heart rate monitor that speaks directly to your smart watch.
You brush your teeth with a sensor toothbrush while listening to music through your showerhead.
You keep your back straight and protect your computer with sensors at your desk.
You watch your kids play basketball with a "smart" ball and shoes.
You unlock your doors, turn on the lights and run your TV with your smartphone.
These wirelessly connected devices are making your life better and less hectic while allowing you to benefit from the convenience, empowerment and freedom of Bluetooth Smart technology.

Is Bluetooth technology hardware or software?

It's a combination of both. When someone says a product contains Bluetooth that means it includes a small computer chip containing the Bluetooth radio. But it also needs software to connect, via Bluetooth wireless technology, to other products.

Those proucts use Bluetooth technology

Android phones, iPhone, tablets, PCs, or TVs can connect with both traditional Bluetooth products and super energy-efficient Bluetooth Smart products such as Smart Home.
Bluetooth wireless technology is built into billions of products, from cars and mobile phones to medical devices and computers and even forks and toothbrushes. Bluetooth technology allows you to share voice, data, music, photos, videos and other information wirelessly between paired devices.
