Bluetooth was designed for low power radio use and can be connected to phones, computers and other network devices. Bluetooth technology was designed primarily for the support of simple wireless networks between devices such as phones, headsets and PDA’s. The wireless signals are transmitted over short distances, usually around 30 feet and communicate at a rate less than 1 mbps.
Bluetooth networks generally connect using dynamic topology known as piconet or PAN. A piconet will contain no less than two and no more than eight peer devices and these peer devices will communicate using protocols originated and designed by Bluetooth specifications.
Bluetooth technology operates using the same 2.4 GHz range as Wi-Fi but is not considered to be a good replacement. Wi-Fi operates at a much faster rate and can offer longer ranges of communication. Wi-Fi is supported on many other platforms and devices than the Bluetooth technology is and will offer a much faster transfer rate and connections speed.
Bluetooth technology allows your device to communicate with up to seven other devices and can alter roles as master or slave. Example; if you are using a headset that is initiating the communication through your phone the headset would be considered the master, but at any time depending on how you use your devices the headset could change roles to be the slave without hesitation or any manual alterations.
A standard Bluetooth phone headset will allow for control of communication through either a phone or a car stereo system. Communication when used between the headset and the PC will require little bandwidth and space and the user can transfer files, contacts or calendar notes using OBEX.
You can find Bluetooth technology in many different devices including the iPod Touch, PlayStation 3, PSP Go, Cellular Phones, Nintendo Wii, headsets, modems, Lego Mindstorms and even some watches. The technology proves to be very useful when the need to transfer information between several devices that are nearby is present.
While Bluetooth has similar applications that are offered by Wi-Fi such as network capabilities, network printing capabilities or transferring files the Wi-Fi technology offers a much more reliable and faster function than the Bluetooth technology. Bluetooth is however a good replacement for cabling and has been used in many smart energy systems such as home thermostats.
Bluetooth technology is present in many of the devices that you use on a daily basis, maybe even without you knowing it. The smooth transfer between information between the devices is there to make life easier, communication more readily available and the devices that use Bluetooth technology are designed to work with each other seemingly and offer a smooth transfer that requires very little manual operation on the users part.
