Difference between Bluetooth and wireless
Bluetooth vs wireless:
Bluetooth and wireless are two very popular technologies that allow different devices to connect with one another and share data from a distance. These two technologies exist in all kinds of computers, laptops and mobile phones alike. However, the purposes that Bluetooth and wireless serve are very different. Therefore, in order to differentiate these two extremely useful devices from one another, it is imperative that their true nature be revealed in a comprehensive manner.
What is Bluetooth?
Bluetooth is a wireless device that enables the users exchange data over a short distance from fixed and mobile devices. In doing so, Bluetooth is capable of creating personal networks with high amounts of security, thus enabling the exchange of information wirelessly over many devices. Introduced in the year 1994 by the telecom vendor Ericson, Bluetooth was first introduced as an alternative to wireless alternative to RS-232 data cables. Today, Bluetooth is managed by Bluetooth Special Interest Group which has in its possession, over 15000 member companies operating in the areas of telecommunication, computing, networking and consumer electronics.
What is wireless?
Wireless can be introduced as a blanket term that is used to refer to all methods of communications that use electromagnetic waves such as radios, satellites, GPS and etc. However, by wireless, most people today imply Wi-Fi, which is a technology that allows computers or the internet to communicate with each other through a wireless router. Developed as an alternative method for restrictive wired networking, wireless facilities are usually found in laptops, PDAs and Smartphones and it is often used to connect the device to internet via a hotspot.
What is the difference between wireless and Bluetooth?
In a sense, Bluetooth too is a wireless technological device that enables two or more devices to connect with each other and exchange data and information without being connected by wires. However, when one mentions wireless, it often refers to the Wi-Fi wireless networking system rather than the whole range of wireless systems that utilize electromagnetic waves to connect with one another instead of being connected through wires. However, the key difference between wireless and Bluetooth would be the fact that while Bluetooth devices communicate with one another in a secured, separate network, wireless network on the other hand is capable of communicating with any other device through a wireless router. Therefore, the number of devices that Bluetooth can reach is limited while this is not the case with a wireless network.
Another difference can be identified when it comes to the range within which the devices can be operated. Bluetooth can only be operated within a few meters of distance, with an exception to class A devices whereas a much greater range is offered in wireless networks in order to offer the users with greater mobility. The range limit on Bluetooth was thus imposed intentionally as a means of reducing security risks. The speed in which data is transferred within the two technologies also differs. While the data transfer between Bluetooth devices is rather slow, one can attain great speed in data transfer with regards to a wireless network. This is due to the fact that the amount of data that needs to be transferred via Bluetooth is rather low and thus it is considered that Bluetooth does not require much bandwidth as wireless.
Wireless has been around much longer than Bluetooth even though both the technologies are still at their primal stages. However, Bluetooth was introduced with the aim of replacing infrared which had a lot of restrictions and also with the aim of replacing cables whereas wireless networking was introduced with the aim of getting rid of the hassle and limitations involved in a wireless network. However, both services are today, available in mobile phones, laptops, computers, Smartphones and the like.
