Bluetooth Cell Phone

Bluetooth cell phones are pretty common – cell phones having become must-have accessories these days and Bluetooth being one of the most convenient ways to transfer data wirelessly. Devices communicate with each other in a myriad ways – through cables, wires and radio waves. For wireless communication, radio waves are the preferred means. Bluetooth technology also makes use of radio waves belonging to a certain frequency. Bluetooth, however, sends very weak signals, which makes it operational only in a very small area – providing what is called as a personal area network (PAN), which is about 10 meters. And the best part is that Bluetooth does all this automatically.

Bluetooth technology provides a solution to all the problems of small-range wireless communication between devices. If you remember, long before Bluetooth cell phones were equipped with infra-red transmission capability. Thus, you could send messages, pictures and songs via infra-red between two cell phones as long as they were pointing at each other’s receivers. However, infrared had some serious limitations. Firstly, it required line-of-sight positioning, which meant any physical interference would cause the signal to break. It was also quite short range. Secondly, infra red would enable communication only between two devices at a time. Bluetooth provides an answer to all these problems.

Bluetooth makes it possible for devices to communicate even in the presence of a physical interference within its range. Therefore your Bluetooth cell phone can easily interact with your hands-free wireless receiver, or your Bluetooth enabled landline or computer which might be in another room. Also, Bluetooth makes it possible to connect to multiple devices. So you could send the same audio or video file to a number of your friends from your Bluetooth cell phone onto theirs. Bluetooth is quite affordable and most cell phones have the capacity inbuilt. The ones that don’t can be equipped with Bluetooth easily and inexpensively.

The best part about Bluetooth is that it functions automatically. Therefore, if you use a Bluetooth headset, every time you turn your phone on, it will automatically look for your headset in its range and will ‘sync’ with it, if it finds it. Thus, all calls automatically get routed to your headset. This makes Bluetooth cell phones especially useful for those who end up talking on the phone while driving. Since using the cell phone while driving is a illegal in most states, Bluetooth headset make it possible for you to answer calls without ever taking your hands off the wheel or having your eyes on the phone. This same feature is taken one step ahead by some Bluetooth cell phone car kits. This is a small Bluetooth enabled device that lets you talk and hear like you do on your phone’s loudspeaker. Thus, you have absolutely nothing on your person.

However, Bluetooth’s automatic capacity is what makes it vulnerable to security threats. Wireless networks and communications are much more prone to hacking and interference than wired ones. It becomes that much easier for someone to intercept messages that you send via Bluetooth. Also, other Bluetooth cell phones can easily pick up your Bluetooth cell phone and infect it with a virus. However, Bluetooth cell phones have advanced security measures to counter this. Most Bluetooth cell phones have security options for you to choose from at the service level and device level. These measures allow users to choose the devices with which the want to communicate and the users from whom they want to receive data. Users can also switch the Bluetooth mode such that other blue tooth phones cannot find them. Anti virus software made for cell phones is also essential to maintain security. In any case, it is essential to know exactly how to protect ones cell phone while using Bluetooth.
