According to one embodiment, a wireless communication apparatus includes a reception unit, a storage unit, a transfer amount decision unit, and a first transfer control unit. The invention additionally relates to liquid-crystalline media and to high-frequency components comprising these media, in particular antennae, especially for the gigahertz range. The mounting system may include at least one rail capable of being connected to a vehicle frame, wherein the rail includes at least one socket. A RC time constant for triggering is set in an operational context according to conditions of usage and desired application of the ESD protection circuit. The TEC dissipates heat sufficiently to allow the EML to be used in the header assembly.
