WebCorded earpieces emit virtually no RF waves (although the phone itself still emits small amounts of RF waves that can reach parts of the body if close enough, such as on the waist or in a pocket). Bluetooth ® earpieces typically transmit RF waves at much lower power levels than cell phones themselves (see below). WebNone of these technologies use infrared waves. The radiation emitted by some wireless local area networks has the shortest wavelength of all the technologies listed above. All these technologies emit waves with a wavelength in the range 0.01 to 10.0 km. All these technologies emit waves with a wavelength in the range 0.01 to 10.0 m.
