*Bluetooth®
technology is the global wireless standard enabling, convenient,
secure connectivity for an expanding range of devices and
services. It is an essential element for bringing everyday objects
into the connected world.
*Created
by Ericsson in 1994. In 1994 a group of engineers at Ericsson, a
Swedish company, invented a wireless communication technology,
later called Bluetooth. In 1998, the original group of Promoter
companies—Ericsson, Intel, Nokia, Toshiba and IBM—came
together to form the Bluetooth Special Interest Group (SIG). Since
no single company owns the technology, the SIG member companies
work together to preserve, educate, and further Bluetooth
technology as a means to bring devices into the connected world.

INFRARED
|
*Infrared
technology
allows computing devices to communicate via short-range wireless
signals. With infrared, computers can transfer files and other
digital data bidirectionally. The infrared transmission technology
used in computers is similar to that used in consumer product
remote control units.

UTP
|
*Unshielded
twisted-pair (UTP) consists of four pairs of thin, copper wires
covered in color-coded plastic insulation that are twisted
together. The wire pairs are then covered with a plastic outer
jacket. The connector used on a UTP cable is called a Registered
Jack 45 (RJ-45) connector. UTP cables are of small diameter and it
doesn’t need grounding.
