It's Safe To Use Bluetooth Technology In Cars

Sphere: Related Content
With more and more parts of modern vehicles being made with computer chips controlling their functions, you might worry that busing Bluetooth technology in cars would mess up your car. Bluetooth gadgets have been known to interfere with medical equipment and occasionally microwave ovens. However, it is highly unlikely that a car with a computer chip in it would ever crash because it used a Bluetooth audio device.

Frequency Hopping In Timeslots

Bluetooth technology in cars can hook your cell phone to a hands-free headset or it can hook up to your iPod and play the music through your car speakers. There are many other things you can use Bluetooth technology in cars, but playing music and talking on the phone are two of the most used activities.

Bluetooth technology in cars works very much like a combination of a radio and a walkie-talkie. It just doesn't pick up one kind of radio frequency, however. It can pick up several frequencies of radio waves. This is how it can concentrate on one source of information at a time, instead of trying to broadcast all radio stations or telephone conversations in the area at once.

Data or information is sent in units called "packets" to your Bluetooth device. This could be your phone sending it to your headset, for example. Your Bluetooth and your cell phone work together to send these packets from one radio frequency to another, never staying on one frequency for too long. Technically, this is called "frequency hopping in timeslots".

Bluetooth can only work in a small area, such as your car. This means that you can't pick up the music from the Bluetooth used in the Hummer next to you and you only hear the music that you want to from your Bluetooth. However, if the Hummer next to you has the window down and the volume set high, you will hear the music. No Bluetooth technology in cars can help you with that…yet.

Be Sensible

Somebody else with a wireless handheld device or a laptop and a good encryption program can listen in on your packets sent between your Bluetooth and your electronic devices. However, they pretty much have to be in the car with you in order to transmit any malware (malicious software). However, you should never have your Bluetooth on when you have somebody you do not know in your car. You also should keep your Bluetooth hidden, if at all possible.
