Bluetooth is usually used to connect mobile phones, laptops and other portable devices. The good thing about it is that it requires no wires and very low power. The user can make just in insignificant effort or even at all. While infrared needs to have the two connectable devices being sited in a line, Bluetooth needs no such thing, having the possibility of connecting them through obstacles and walls on a very long distance. Nowadays, a prototype circuit only needs a 0.9 cm square board and they are now working at a smaller circuit board.
When one Bluetooth detect another one, they will make an exchange of data containing the addresses and the details of capability. Once this happens, the two devices will establish a 1 MB link. This connection speed is standard and they will also establish security as needed.
The radio supports three voice channels and a speed of 721 KBps. The frequency band that the radio operates is of2.45 Ghz. Bluetooth uses frequency hooping, which stops radio interferences by changing his frequencies. This is a reason why radio transmitted by Bluetooth is so hard to listen to.
Bluetooth allows a distance of 10 meters maximum, but it can be modified until 100 meters which means more energy lost. But even like this, the device will not drain your battery’s life because it has been designed to need and use as low energy as possible.
You can talk and transmit data at the same time. When it comes about communication, Bluetooth surpasses without any problem his resembling, the infrared. Well, while reading these sentences above, I hope you realize that Bluetooth is very hard to compete with. It represents the best method of wireless device in the world. More and more people use it once and stick with it forever because of his impressing technology.
