3. Introduction
Technology is advancing rapidly, and among the latest innovations
that are fundamentally changing the way we communicate with
wireless devices, Bluetooth technology stands out. It is a wireless
technology that allows for seamless data and audio transfer
between compatible devices, without the need for cables or
connectors. In this research, we will discuss the concept of
Bluetooth, its history, versions, advantages, disadvantages, and
applications.
4. What Is Bluetooth?
Bluetooth is a wireless technology developed to enable devices to communicate
and exchange data over short distances using radio waves at specific
frequencies, between 2402 and 2480 megahertz, or 2400 and 2483.5 megahertz.
Without wires or cables or any user intervention.
Bluetooth is managed and developed by the Bluetooth Special Interest Group
(SIG), a technology organization responsible for developing and enhancing
Bluetooth technology and its standards, which includes over 30,000 member
companies.
5. Label:
The name "Bluetooth" is directly
inspired by the alias of the Danish
Viking king Harald Bluetooth,
known for successfully unifying
Danish tribes within the same
kingdom. This name was
proposed in 1997 by engineer Jim
Kardach from Intel, and the
implicit meaning of this name is
that just as King Harald unified
his country and brought Norway
and Denmark together, Bluetooth
connects communications and
computers and "unifies" devices
with each other.
I am King Harold Bluetooth who
unified warring Viking Tribes in
the 10th Century. In the 21st
Century a wireless Bluetooth
network is named after me.
History Of Bluetooth
6. History Of Bluetooth
(Cont.)
The Origin:
The development of "short-
link radio," which was later
named Bluetooth, began in
1989 by Nils Olsson at
Ericsson telecommunications
company in Lund, Sweden.
The goal was to develop
wireless headsets.
Logo:
The Bluetooth
logo is the
result of the
combination of
the runic letters
ᚼ (Hagall) and
ᛒ (Bjarkan),
which form the
name Harald
Bjarkan.
