Companies like Nokia and Intel had very similar ideas, including the concept of linking cellphones, computers, and developing devices like wireless, short-range headsets. What the companies thankfully understood was that in order to create a protocol that would seamlessly work across a number of devices from a multitude of companies, the protocol had to be standardized so that it could be universally applied.
It was an important moment in the history of Bluetooth, in fact, as this was also when its name was suggested. Harald not only introduced Christianity to Denmark, he also unified various clans under a single banner.
The name, as it often happens, stuck. The marketing teams could not come up with anything better, so the name and logo of a technology used a thousand years later is owed to an old King. As for the Bluetooth SIG, it grew remarkably fast.
By the end of the first year alone, SIG had more than members. Today, it has more than 30, Bluetooth took quite some time to be introduced to a mainstream, consumer audience. The technology was considered obscure even amongst tech circles as the companies involved struggle to explain and launch it in an affordable and simple manner. Yet in , a host of Bluetooth-enabled devices were unleashed. These includes a mobile phone, headset, mouse, laptop, and a PC card. Eight devices can connect to the same piconet at once and multiple piconets can operate on the same device at the same time.
When connected to the piconet, one device that has been designated as a master can transmit data to one or more slave devices.
Each piconet can handle digital communications involving voice, data, printing, faxes and more, and the ability to operate multiple piconets at the same time enables Bluetooth to provide an incredible amount of short-range telecommunications functionality.
Between and , Haartsen served as the chairman of the SIG air protocol certifications group, helping to standardize the Bluetooth radio communications protocol. The standardized nature of Bluetooth which allows all of these dynamic wireless networks among a diversity of electronic devices is why the 10th century Danish king came to serve as the namesake for a Swedish technology. Kardach was in Toronto, Canada, presenting wireless technologies to SIG companies along with Mattisson and the two traded stories during a wintry pub crawl, during which Mattisson brought up the figure of Harald Bluetooth.
Soon thereafter, Kardach received a history book entitled The Vikings and a representation of Bluetooth was one of the first things that Kardach came across. When he and others made the connection that, much like Harald Bluetooth, the wireless technology sought to unify a lot of separate entities into a single system , the name seemed like the best fit at the time. 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. Patent No. The patent discloses a wireless network with a master unit and a slave unit, the master unit being capable of communicating with the slave unit by means of a virtual frequency hopping channel. The invention solved a need for a cost-effective wireless local network supporting both voice and data transmissions by enabling self-organization techniques to make efficient use of limited available radio spectrum.
The patent application was filed in September and was issued by the U. Listen to our podcast. Calendar of events Search for events and training by topic, date, location or target audience.
