Device for control of data transfer in local area network
First Claim
1. A wearable electronic communication device for a portable electronic communication device, the wearable device is configured for Body Coupled Communication (BCC) and capacitance measurement in close proximity to a person'"'"'s body and comprises:
- a BCC antenna over which BCC is carried out and that functions as a capacitance sensor that makes a body capacitance measurement, wherein if the body capacitance measurement belongs to a predefined capacitance range, the body capacitance measurement indicates that the wearable device is in close proximity to or in contact with a body part of the person, andprocessing circuitry in operational connection with the BCC antenna, the processing circuitry controlling the BCC and the body capacitance measurement, whereinthe antenna and the capacitance sensor are the same structural entity arranged as one common electrode for both the BCC and the body capacitance measurement of the wearable device, the processing circuitry comprising a first impedance used when the common electrode is used for body capacitance measurement and a second impedance used when the common electrode is used for BCC.
