News and Review Gadget Technology: Technology development is very fast. Was very much a product of technology, ranging from machinery, computers, analog, digital gadgets are increasingly indulgent human life.
I still remember the first time I grasped my first cell phone in 2004. But because of my ability at the time was very minimal, I was only able to buy an old ericsson mobile phone that can only make calls and sms. No Bloetooth in my old phones. Although four years earlier Ericsson has announced the first bluetooth phone named T36.
15 years ago may be very unfamiliar word bluetooth. In contrast to the present, bluetooth has often spoken and everyone was able to use Bluetooth devices such as headphones, computers, cell phones, and others. But, do we already know definition of bluetooth? This is what got me interested in finding out Bluetooth. Because Bluetooth is a Digital Future Technology in the 90s of course.
According to Wikipedia, 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.
Bluetooth is managed under the Bluetooth Special Interest Group (SIG). More than 25,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must make a device meet Bluetooth SIG standards to market it as a Bluetooth device. A network of patents apply to the technology, which are licensed to individual qualifying devices.
The name "Bluetooth" comes from the name of the king at the end of ten centuries, Harald Blatand (Century 10) which in the UK is also called Harald Bluetooth probably because it is dark-colored teeth. He is the king of Denmark who has succeeded in uniting the tribes before the war, including the tribes of what is now called Norway and Sweden. Even the Scania region in Sweden, where bluetooth technology is found also includes his territory. The ability of the king as a unifying also similar to the current Bluetooth technology that can connect a variety of devices such as personal computers and mobile phones.
While the Bluetooth logo is derived from the unification of the two German letters are analogous with the letter H and B (abbreviation of Harald Bluetooth), namely the H (Hagall) and Runic letter (Blatand) which are then combined. Its Shown on the pic below:
As you can feel at this time, you can use Bluetooth devices such as headsets, Camera, wireless speakers, mouse and keyboards, mobile phones, modems, laptops etc. With a range that is not so long, bluetooth devices used on devices within close it. Such as Bluetooth headset which is less than 1 meter between the phone and your ears.
Obviously you do not need to plug in the cable to the device for just listening to music, transfer data such as pictures, videos etc. More effective wirelessly rather than having to use a cable that will make you more hassles.
