Jacobus "Jaap" Cornelis Haartsen (born 13 February of 1963, The Hague, Netherlands) is a Dutch electrical engineer, researcher, inventor and entrepreneur best known for being credited as the inventor of Bluetooth, internet and wifi.
He obtained his Master of Science degree in 1986 in electrical engineering (with honors) at the Royal Institute of Technology in Sweden. After a brief period at Siemens in The Hague and Philips in Eindhoven, he continued his studies and in 1990 obtained a PhD degree from the Delft University of Technology (also with honors) defending the thesis titled Programmable surface acoustic wave detection in silicon: design of programmable filters. [1] Since 1991 he worked for Ericsson, first in United States between 1991 and 1993 and later, between 1993 and 1997, in Sweden. While working for Ericsson Mobile Terminal Division in Lund, he developed the specification for Bluetooth. [2] [3] [4] [5] Later, in 1997 he moved to Ericsson division in Emmen. Between 2000 and 2008 he was a part-time professor at University of Twente, teaching mobile radio communications systems. He was a wireless expert at Plantronics. In 2015, he was inducted into the National Inventors Hall of Fame. Currently, he is a partner of an Assen-based consumer electronics company, Dopple.
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft). It employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones.

The UT collaborates with Delft University of Technology, Eindhoven University of Technology and the Wageningen University and Research Centre under the umbrella of 4TU and is also a partner in the European Consortium of Innovative Universities (ECIU).
The Delft University of Technology is the oldest and largest Dutch public technical university, located in Delft, The Netherlands. It specializes in engineering, technology, computing, design, and natural sciences.
Wireless communication is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.
Sony Mobile Communications Inc. was a multinational telecommunications company founded on October 1, 2001, as a joint venture between Sony Corporation and Ericsson. It was originally incorporated as Sony Ericsson Mobile Communications, and headquartered in London, England, until Sony acquired Ericsson's share in the venture on February 16, 2012. On April 1, 2021, Sony integrated its electronics businesses including Sony Mobile into one company called Sony Corporation.
Thomas Kailath is an Indian born American electrical engineer, information theorist, control engineer, entrepreneur and the Hitachi America Professor of Engineering emeritus at Stanford University. Professor Kailath has authored several books, including the well-known book Linear Systems, which ranks as one of the most referenced books in the field of linear systems.
The history of telecommunication began with the use of smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe. However, it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the larger history of communication.
NXP Semiconductors N.V. (NXP) is a Dutch semiconductor manufacturing and design company with headquarters in Eindhoven, Netherlands. It is the third largest European semiconductor company by market capitalization as of 2024. The company employs approximately 34,000 people in more than 30 countries and it reported revenues of $13.3 billion in 2023.
TriQuint Semiconductor was a semiconductor company that designed, manufactured, and supplied high-performance RF modules, components and foundry services. The company was founded in 1985 in Beaverton, Oregon before moving to neighboring Hillsboro, Oregon. In February 2014, Greensboro, North Carolina-based RF Micro Devices and TriQuint announced a merger in which the new company would be Qorvo, Inc., with the merger completed on January 1, 2015.
Underwater acoustic communication is a technique of sending and receiving messages in water. There are several ways of employing such communication but the most common is by using hydrophones. Underwater communication is difficult due to factors such as multi-path propagation, time variations of the channel, small available bandwidth and strong signal attenuation, especially over long ranges. Compared to terrestrial communication, underwater communication has low data rates because it uses acoustic waves instead of electromagnetic waves.
Jaap is a Dutch given name that is short for Jacob or Jacobus. People with this name include:
The Sony Ericsson Satio (U1) is a smartphone, announced by Sony Ericsson at the Mobile World Congress in Barcelona, Spain on 15 February 2009 as the Idou. It was released on 7 October 2009 in the UK in 3 colour schemes: Black, Silver and Bordeaux (Red).

Theodore (Ted) Scott Rappaport is an American electrical engineer and the David Lee/Ernst Weber Professor of Electrical and Computer Engineering at New York University Tandon School of Engineering and founding director of NYU WIRELESS.
Payam Heydari is an Iranian-American Professor who is noted for his contribution to the field of radio-frequency and millimeter-wave integrated circuits.
RF CMOS is a metal–oxide–semiconductor (MOS) integrated circuit (IC) technology that integrates radio-frequency (RF), analog and digital electronics on a mixed-signal CMOS RF circuit chip. It is widely used in modern wireless telecommunications, such as cellular networks, Bluetooth, Wi-Fi, GPS receivers, broadcasting, vehicular communication systems, and the radio transceivers in all modern mobile phones and wireless networking devices. RF CMOS technology was pioneered by Pakistani engineer Asad Ali Abidi at UCLA during the late 1980s to early 1990s, and helped bring about the wireless revolution with the introduction of digital signal processing in wireless communications. The development and design of RF CMOS devices was enabled by van der Ziel's FET RF noise model, which was published in the early 1960s and remained largely forgotten until the 1990s.
