Bluetooth
Although IR adaptors used to be common in personal computing devices,
the technology was pushed aside as alternatives such as Bluetooth emerged.
Bluetooth is a wireless personal area network technology based on a specification
that was created in the late 1990s. The technology allows for the
transfer of data between devices over short distances.3 Rather than line of
site, Bluetooth uses radio frequencies (modulating in the unlicensed 2.4GHz
band) to create a link between devices. To avoid interference with other
signals in the band, Bluetooth hops to a new frequency after transmitting or
receiving a data packet. Bluetooth is designed to let smaller, more personal
devices communicate wirelessly, eliminating the need for USB cables to
make connections between computers and peripherals, data synchronization
for mobile devices, wireless headphones, and hands-free mobile phone use.
