Who invented bluetooth

Bluetooth technology Working in the mobile phone division of Ericsson in the mid-1990s, Dutch engineer Jaap Haartsen found a revolutionary way to connect electronic gadgets to each other at short range without the use of cables, using a variety of low-power radio frequencies.

When did Bluetooth invented?

The technology was publicly announced in May 1999 and the first specifications were released in July 1999. In 2000, Ericsson launched its first Bluetooth product: a wireless voice headset.

What country invented Bluetooth?

The development of the "short-link" radio technology, later named Bluetooth, was initiated in 1989 by Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden.

Who owns the Bluetooth patent?

There are about 10 patents protecting Bluetooth technology according to the Centre for Business History in Stockholm, most of which are held by Ericsson. The patent which brings Haartsen his hall of fame acclaim is U.S. Patent No.

Why it is called Bluetooth?

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.

What is Bluetooth used for?

Connect Different Devices As Bluetooth's main purpose is to create a wireless connection between two devices, there are many devices that can be connected using Bluetooth.

How did we discover Bluetooth?

The origins of Bluetooth can be traced back as far as 1994 when Dr. Jaap Haartsen was tasked with finding short-range radio connections. Working at Ericsson's Mobile Terminal Division, the company wanted to find a way to enrich the functionality of mobile phones which had been growing in popularity at the time.

What is the distance of Bluetooth?

The range of the Bluetooth® connection is approximately 30 feet (10 meters). However, maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. NOTE: Not all audio devices are supplied with Bluetooth capability.

Who invented WiFi and Bluetooth?

Hedy Lamarr was an Austrian-American actress and inventor who pioneered the technology that would one day form the basis for today's WiFi, GPS, and Bluetooth communication systems.

Which country invented WiFi?

A prototype test bed for a wireless local area network (WLAN) was developed in 1992 by researchers from the Radiophysics Division of the CSIRO (Commonwealth Scientific and Industrial Research Organisation) in Australia.

Who owns patent for Wi-Fi?

The Owner of the WLAN Patent One key patent for Wi-Fi technology that has won patent litigation lawsuits and does deserve recognition belongs to the Commonwealth Scientific and Industrial Research Organisation of Australia. CSIRO invented a chip that greatly improved the signal quality of Wi-Fi.

What frequency is Bluetooth?

2.45 GHz Bluetooth / Frequency

Who invented Bluetooth logo?

Engineers Sven Mattisson Jim Kardach were working on the technology in the late 1990s when they realised it needed a catchy name to make it stand out from the confusing plethora of wireless tech being developed at the time.

What is the max speed of Bluetooth?

	BLUETOOTH v2.1	BLUETOOTH 4.0 (LE)
Max range (free field)	Around 100 m (class 2 outdoors)	Around 100 m (outdoors)
Frequency	2.402 – 2.481 GHz	2.402 – 2.481 GHz
Max data rate	1- 3 Mbit/s	1 Mbit/s
Application Troughput	0.7-2.1 Mbit/s	Up to 305 kbit/s

What is Bluetooth short answer?

Bluetooth technology is a short-range wireless communications technology to replace the cables connecting electronic devices, allowing a person to have a phone conversation via a headset, use a wireless mouse and synchronize information from a mobile phone to a PC, all using the same core system.

What is Bluetooth also known as?

Bluetooth is also known as IEEE 802.15 standard or specification that uses low power radio communications to link phones, computers and other network devices over a short distance without using any type of connecting wires.

Is Bluetooth a Wi-Fi?

Bluetooth allows for short-range data transfer between devices. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Wi-Fi, on the other hand, allows devices to connect to the Internet.

Does Bluetooth use Wi-Fi?

No, it doesn't. Even though some devices may have Bluetooth and WiFi capabilities, Bluetooth itself is not reliant on internet connectivity. Bluetooth and WiFi are both radio frequency technologies that wirelessly connect electronic devices, but there are some important differences in how they operate.

Why is Bluetooth free?

Bluetooth doesn't use data, but instead uses short-range radio waves to connect devices. You can use Bluetooth devices even if you don't have cellular service or an internet connection. If you think that your Bluetooth connection is using data, it's more likely that an app you're using is the culprit.

What was used before Bluetooth?

Initially, Intel called its technology “Biz-RF,” while Ericsson called its mechanism “MC-Link” and Nokia used the terms “'Low Power-RF.” Then longtime Intel engineer Jim Kardach proposed that the name Bluetooth be used — at least temporarily.
