Surprisingly, the name dates back more than a millennia to King Harald “Bluetooth” Gormsson who was well known for two things: Uniting Denmark and Norway in 958. His dead tooth, which was a dark blue/grey color, and earned him the nickname Bluetooth.

Why Does Bluetooth have a short-range?

Bluetooth uses a spread-spectrum frequency-hopping technology. This means it uses multiple frequencies at the same time to limit interference when using multiple devices. While Bluetooth does not need a direct line of sight, the signals do not carry very far, and the devices need to be within approximately 10 meters.

What is a short-range wireless communication technology?

Short-region wireless technology refers to the technology that can communicate wirelessly within a smaller diameter region, within a minimum level of one millimeter. The common short-region wireless communication modes are UWB, Wi-Fi, ZigBee and bluetooth.

What is the name of Bluetooth?

Bluetooth
Bluetooth was named after a tenth-century king, Harald Bluetooth, King of Denmark and Norway. (Also known as Harald Bluetooth Gormson or Harald I of Denmark) Bluetooth is an anglicized version of Harald Blaatand, who was known for his unification of previously warring tribes from Denmark (including now Swedish Scania).

What is a short range wireless communication technology called Class 9?

Answer: Zigbee is a wireless communication technology for short-range, low-power digital radio communications.

How does Bluetooth communication work?

Bluetooth uses radio waves instead of wires or cables to transmit information between electronic devices over short-distances. Then, the communication between the two Bluetooth devices happens over a short-range network called a piconet (pico means really really small in the metric system).

Which of the following are short range technologies?

Short-range wireless technologies include Bluetooth, Wi-Fi, near-field communication (NFC), ultra-wideband (UWB) and IEEE 802.15. 4. They are fabricated on RF CMOS integrated circuit (RF circuit) chips.

What is the Bluetooth logo?

The squiggle of shapes in the bright blue brandmark comes from the runes in the Roman alphabet representing “H” and “B”. In other words, they’re the initials for Harald Bluetooth. In technical terms, the Bluetooth logo is a “bind-rune”. This simply means that it’s an image made up of two runes merged together.

Which of the following has wireless ultra short-range connectivity?

The correct answer is Bluetooth. Bluetooth facilitates short-range wireless connectivity. It uses ultra-high-frequency radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs).

What is the origin of the Bluetooth symbol?

Bluetooth Symbol Origin and Meaning. The Bluetooth logo is the combination of “H” and “B,” the initials of Harald Bluetooth, written in the ancient letters used by Vikings, which are called “runes.”.

What is wireless communication – Bluetooth?

Wireless Communication – Bluetooth. Bluetooth wireless technology is a short range communications technology intended to replace the cables connecting portable unit and maintaining high levels of security. Bluetooth technology is based on Ad-hoc technology also known as Ad-hoc Pico nets, which is a local area network with a very limited coverage.

What is Bluetooth protocol?

Bluetooth specification details the entire protocol stack. Bluetooth employs Radio Frequency (RF) for communication. It makes use of frequency modulation to generate radio waves in the ISM band. The usage of Bluetooth has widely increased for its special features.

What is Bluetooth and how does it work?

Bluetooth is also widely used to establish a wireless connection between a computer and various peripheral devices, including a mouse, keyboard, printer, digital camera, etc. Many modern electronic devices have Bluetooth built in, such as remote controls for video games.
