3. 11-Jun-16 www.fakengineer.com Why is it called Bluetooth? Harald Bluetooth was king of Denmark in the late 900s. He managed to unite Denmark and part of Norway into a single kingdom then introduced Christianity into Denmark. He left a large monument, the Jelling rune stone, in memory of his parents. He was killed in 986 during a battle with his son, Svend Forkbeard. Choosing this name for the standard indicates how important companies from the Baltic region (nations including Denmark, Sweden, Norway and Finland) are to the communications industry, even if it says little about the way the technology works.

25. 11-Jun-16 www.fakengineer.com Bluetooth ::How it works ? Unlike infrared which uses a beam of light to transmit data and is found in many remote controls, wireless keyboards, Bluetooth uses a radio frequency (2.4 Ghz) to communicate. Unlike infrared which uses a beam of light to transmit data and is found in many remote controls, wireless keyboards, Bluetooth uses a radio frequency (2.4 Ghz) to communicate. The biggest advantage that Bluetooth has over IR is that one device doesn’t need to be in the line of sight of the device that it’s communicating with,so it can work through walls and floors.

Bluetooth enabled devices can find each other without the user’s having to do anything. When two Bluetooth devices come within range of each other, they immediately begin a series of negotiations to determine if they have data to share or need to make a connection, and they form a small network known as a piconet or a personal area network (PAN).
