INFRARED Vs BLUETOOTH


INFRARED:-
=-> Infrared technology is what most TV remotes use..
=-> The distance an infrared signal can travel varies based on the strength of the remote, but is usually less than 50 feet for household electronics..
=-> In order for an infrared signal to be detected, there must be a direct line of sight between the transmitter (REMOTE) and the receiver (TV). If there is a wall or large object between them, the signal will not pass through it..

BLUETOOTH:-
=-> Bluetooth uses a radio frequency, which allows transmission through walls and other objects..
=-> The standard range of a Class 3 Bluetooth device is about 30 ft., which makes it ideal for syncing PDAs with computers, using wireless cell phone headsets, and enabling handsfree cell phone use inside Bluetooth-enabled automobiles..
=-> Bluetooth technology is based on a standard 2.4 GHz frequency, different Bluetooth devices can typically communicate with each other, regardless of the manufacturer..
