Bluetooth is the latest communications technology that uses radio waves to transfer information from one device to another over short distances. This means that as Bluetooth uses radio waves, there is no need for any wires or cables between the two devices. Bluetooth therefore enables you to transfer music and other information from your PC or laptop, to your cell phone or even from one cell phone to another, providing that the devices, the sender and the receiver, both have Bluetooth. Although transferring music and other data from one device to another is a popular use for Bluetooth, it can have more important uses, especially within the field of medicine and already the medical profession is using Bluetooth to transfer data such as someone’s heart rate and other vital statistics, to their doctor, saving precious time. Although most electronic devices bought today have probably got the Bluetooth technology fitted in them, as the technology only became available in the early 2000s, you may have a device that does not have it fitted but this need not be a problem as there are Bluetooth receivers available to buy. In fact there are so many that before you buy one, you may want to compare blue tooth receivers to see which would be best suited for your exact needs. Although there are several types of Bluetooth receivers, the main two are Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and Bluetooth Low Energy (LE). The first is limited in range but is better for use when a continuous stream of data is needed to be transferred whilst the second, Bluetooth Low Energy, is ideal for situations where short bursts of data are needed to be transferred or when saving energy is important.
As with everything involving communications today, it seems to be the younger generation which catches on to it first and Bluetooth is no exception with youngsters asking if a device has Bluetooth, before accepting it. This is perhaps understandable as it was the older generation, as the younger generation, that seemed to understand the introduction of records, cassettes and CDs before their parents did. This does mean though that in order to hold their place in the market place, any manufacturer of electronic items must include Bluetooth in its makeup. Although many of the newer communications technologies only receive interest for a short period of time, the usefulness of Bluetooth means that it should be around in one form or another, for quite some time. To understand it better, although Bluetooth does not require the internet in any way, it can perhaps be compared to a type of Wi-Fi which also helps to transfer information without the need for wires but in the case of Wi-Fi, it can only be used in conjunction with the internet. With both Wi-Fi and Bluetooth though, you can be assured that you can keep up with any information whilst still on the move and without too much weight or stress having to be taken with you.
