Examples relating to techniques for wireless communications, e.g., visible light communication, VLC, are disclosed. In particular, there is disclosed a communication device for communicating with a plurality of other devices, using a wireless link. The device provides individual reference signals using a number of subcarriers or time slots in accordance to the optical clock reference and the number of transmitting devices in the set or streams to be transmitted in parallel. The device defines the position of subcarriers or of signals at the time slots in accordance to an identification number associated to an individual device within the whole set of transmitting devices or in dependence on an identification number identifying a specific stream or transmitter. The device transmits the reference signal which enables the plurality of receiving devices to identify the signal coming from the individual communication device in the whole set of devices.

The present invention relates to a lancet device, by which a lancet can be displaced along a piercing path for generating a piercing wound in a skin surface, in particular to obtain bodily fluid for diagnostic purposes, comprising a lancet drive having drive means to generate a drive force for a piercing movement of the lancet along the piercing path in the direction toward the skin surface. According to the present invention, the lancet drive comprises a magnet, by which a magnetic retention force oriented opposite to the drive force may be generated, and the lancet drive also comprises triggering means, by which the retention force may be reduced enough that the lancet is accelerated in the direction toward the skin surface under the effect of the drive force generated by the drive means. The present invention also relates to a method for generating a piercing wound, in which the drive spring is held in a tensioned state using a magnetic retention force oriented opposite to the drive force before the triggering of a piercing wound.
