Abstract:

Any around-the-body wireless system faces challenging requirements. This is especially true in the case of audio streaming around the head e.g. for wireless audio headsets or hearing-aid devices. The behind-the-ear device typically serves multiple radio links e.g. ear-to-ear, ear-to-pocket (a phone or MP3 player) or even a link between the ear and a remote base station such as a TV. Good audio quality is a prerequisite and mW-range power consumption is compulsory in view of battery size. However, the GHz communication channel typically shows a significant attenuation; for an ear-to-ear link, the attenuation due to the narrowband fade dominates and is in the order of 55 to 65dB [1]. The typically small antennas, close to the human body, add another 10 to 15dB of losses. For the ear-to-pocket and the ear-to-remote link, the losses due to body proximity and antenna size reduce, however the distance increases resulting in a similar link budget requirement of 80dB.
