Because of this, the frequencies are able to penetrate living tissue down to a cellular level. They can travel long distances without a wire. These types of frequencies have a short wavelength and a rapid rate of oscillation. We can also call this radiation microwave frequencies. It also refers to another form of radiation coming from your Bluetooth devices. But contrary to what you may be thinking, it turns out that microwave radiation doesn’t just refer to the thermal radiation or heat waves, you use to warm up leftovers. Well, chances are you’ve heard of microwave frequencies. Your Bluetooth devices are designed to surpass this lower frequency radiation using UHF.īut what kind of high-frequency radiation are we talking about, exactly? These devices also continuously emit radiation, but they rely on low-frequency signals to function. This is in contrast to most of the other devices you use daily, such as your TV or radio. So, the high-frequency signals from your activated Bluetooth devices, while weak, are being continuously emitted in a concentrated area around you. Cell phones are lower, at 700, 900 and even 1900 MHz. The signals from this band can travel up to around 10 meters.īluetooth transmitters are in the same MHz (megahertz, or EM wave frequency) category as WiFi routers, tablets, and microwaves: between 2400-2500 MHz. When Bluetooth is being used, it emits low power radio transmission signals in an ultra high-frequency band (UHF). ![]() But how exactly does this technology work, and how concerned should you be about how it’s affecting you? The first thing that comes to mind when you hear “Bluetooth” is the convenient hands-free headsets you put on your head so you can communicate while walking down the street or while driving your car. This article explains Bluetooth radiation and potential health concerns. ![]() ![]() However, we don't have enough studies or time to know if our everyday Bluetooth exposures are safe. How Bluetooth Devices Can Negatively Affect Your Healthīluetooth technology has brought us great convenience: hands-free ear phones smart ovens smart watches and many other "smart" devices that can communicate with other devices and provide us with interesting information.
