Infrared technology is used in remotes. the more the strength of the remote the more the infrared rays can travel, but for household electronics the range is less then 50 feets. in order to have a signal detected there should be a straight line between the transmitter and the receiver. If
there is a wall or large object between the transmitter and receiver than the signal will not pass through
it.
Bluetooth uses a radio
frequency, which allows transmission of infrared signal through walls and other big objects. The
range Bluetooth device is about 30 ft. Because
Bluetooth technology is based on a standard 2.4 GHz frequency, different
Bluetooth devices can easily communicate with each other, regardless of the
manufacturer. this means that it can be of any company not necessary Samsung or acer or any other manufacturer. While Bluetooth is well on its way to replacing infrared in many different areas, the technology is not meant to be used for wireless networking. Instead, wifi technology, which has a larger range and higher bandwidth than Bluetooth, is the standard that most wireless networking equipment uses to compare.
