BLUETOOTH

Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmission over short distances from fixed and / or mobile devices, creating wireless Personal Area Networks (PANs). The intent behind the development of bluetooth was the creation of single digital wireles protocol, capable of connecting multiple devices and overcoming issues arising from syncronization of these devices. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, GPS receivers, digital cameras, and video games consoles over a secure, globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency bandwith. The bluetooth specifications are developed and licensed by Bluetooth Special Interest Group (SIG). The Bluetooth SIG consist of companies in the areas of telecommunication, computing, networking, and consumer elektronic.

The Original the name and the logo

Bluetooth was named after a tenth-century king, Harald Bluetooth, King of Denmark and Norway. Bluetooth is an anglicized version of harald blaatand, who was known for his unification of previously warring tribes from Denmark (including now Swedish Scania, where the bluetooth technology was invented), and Norway. Bluetooth likewise was intended to unify different technologies, such as personal computers and mobile phones.
The name may have been inspired less by the historical Harald than the loose interpretation of him in The Long Ships by Frans Gunnar Bengtsson, Swedish Viking-inspired novel.
The Bluetooth logo merges the Germanic Runes analogous to the modern latin letter H and B; (for Harald Bluetooth) Hagall and Berkanan; merged together, forming a bind rune.

Mobile Phone

The mobile phone (also called a wireless phone or cellular phone) is a short-range, portable elektronic device used for mobile voice or data communication over a network of specialized base stations known as cell sites. in addition to the standard voice function of telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the internet, gaming, bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video. Most current mobile phones connect to cellular network of base stations (cell sites), which is turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).
According to internal memos, American Telephone & Telegraph discussed developing a wireless phone in 1915, but were afraid deployment to the technology could undermine its monopoly on wired service in the U.S
The first commercial mobile phone service was launched in Japan by NTT in 1978. by November 2007, the total number of mobile phone subcriptions in the world had reached 3,3 billion, or half of human population (although some user have multiple subcriptions, or inactive subcriptions), which also makes mobile phone the most widely spread technology and the most common gadget in the world.
The fisrt mobile phone to enable internet connectivity and wireless email, the Nokia Communicator, was released in 1996, creating a new category of expensive phones called smartphones. In 1999 the first monile internet service was launched by NTT DoCoMo in Japan under i-Mode sevice. by 2007 over 798 million people around the world accessed the internet or equivalent mobile internet service such as WAP and i-Mode at least occasionally using a mobile phone rather than a personal computer.
