Get To Know Bluetooth Technology

Bluetooth Technology

Once a novelty, ‘Bluetooth’ has now become a word generously strewn over all types of communication devices. Consumer electronics in fact, from PCs to fitness equipment, seem to be better off with Bluetooth in them. Although, owing to abundant usage of the term, it may not be immediately apparent, Bluetooth is now the trade name for technology and is managed by The Bluetooth Special Interest Group. The SIG includes many members, and licenses them to use the technology. Today, every common device has Bluetooth available, and new uses for the technology are constantly being discovered.

Bluetooth is a smart method of data transfer, eliminating the need for cables, and streamlining large transfers. It offers a host of benefits over wired communication, most of which don’t exist with any other technology. The physical range of the technology, to date, is 100 metres. This in effect means all needs the average user may have for interfacing devices within one physical space, can be met with Bluetooth technology. It allows for many devices to be connected to each other, as opposed to many one-on-one technologies that only allow data transfer between two devices. With a simple interface and sufficient access, any number of devices can be paired together. However, individual recipients can be targeted, even with multiple devices in the same Bluetooth network, through the use of identifiers.

Any wireless technology will invariably offer faster speeds than a wired one, and Bluetooth is no exception. Through the years, Bluetooth has adapted and updated its protocols to offer increasingly faster speeds. While the original concept offered a modest one megabyte per second transfer rate, today’s high level protocols are capable of transferring at 25Mb or more per second. While this requires all involved devices using the newest protocol, Bluetooth is backwards compatible, and will function with older devices, at lesser speeds.

The newest versions of Bluetooth (3.0, and 4.0) vastly improve on the technologies energy saving operation. Bluetooth uses very little energy to power itself, a key ingredient for battery-saving in mobile devices. Besides a newly introduced ‘low energy profile’ that is exclusive to Bluetooth 4.0, all versions utilize low energy signals to communicate, and don’t drain a power source. Bluetooth is also fully automatic. That is, with the specified range, any devices that ‘meet’ each other will start to communicate, with no initiation required. Bluetooth signals aren’t hampered by most obstacles either, making communication within an enclosure possible. Using low frequency signals also means the technology won’t be interrupted or interfere with other wireless networks.

Having achieved a standardized implementation, Bluetooth technology is here to stay, and future developments guarantee faster speeds and longer ranges. With all the advantages it offers, it is pleasing to know that Bluetooth is cheap, and easy to implement on devices. More devices apparently unrelated to communication, will begin to use it, as it integrates seamlessly with smart homes and offices. Public services and health organisations are already using Bluetooth extensively, in a variety of applications. It has the potential, in time, to completely replace other forms of networking.
