Bluetooth & Health - L1

Bluetooth wireless technology is a short-range radio technology that uses radio frequency fields to transmit signals over short distances between telephones, computers and other devices. The technology offers simplified communication and synchronization between devices without the need for cables.

A common application is a Bluetooth headset connected to a mobile phone.  The headset will only operate within a few metres of the phone.

Bluetooth operates in the radio frequency range of 2.4 to 2.485 GHz at very low power, typically about 2.5mW which is approximately 100 times less than the maximum power of a mobile phone.  The Bluetooth signal is constantly adjusted amongst 79 frequencies which minimizes any interference from other radio frequency emitting devices.

There has been a lot of research conducted worldwide to investigate possible health effects of radio communications and wireless technology.

In relation to radio frequency emissions and wireless technology and health, the general conclusion from the World Health Organization (WHO) is;

Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health
