D. 940??“
981. Bla??tand loosely translates to ??????blue tooth.??™??™During his reign, King Harald
Bla??tand is supposed to have united and controlled Denmark and Norway.
Because this new radio technology was expected to unify the telecommunication
and computing industries, it seemed fitting to name it after King
Harald. A part-time historian on the team proposed Bluetooth as the internal
code name. Because the Bluetooth SIG marketing team could not come up
with a better name that was not already trademarked, the name stuck.
1.2.2 Bluetooth Vision
Bluetooth wireless technology was originally developed as a cable replacement
technology for connecting devices such as mobile phone
handsets, headsets, and portable computers with each other (Figure 1.2).
However, wireless connectivity between fixed and mobile devices enables
many usage scenarios other than cable replacement. By enabling wireless
links and communication between devices, a short-range wireless network
was created that gave rise to the notion of a personal area network.
Designed as an inexpensive wireless networking system for all classes of
portable devices, Bluetooth devices have the capability to form ad hoc
networks. These networks should enable easy and convenient connections
to printers, Internet access points, and personal devices at work and at
home.
