A system and method for transmitting wideband signals via a radio communication system adapted for transmitting narrow-band signals is described. This polypeptide provides a novel diagnostic means for hepatitis by determining the production level of the polypeptide or an mRNA encoding the polypeptide in the liver. A Multiple-Input Multiple-Output signal is received in the terminal via multiple receive antennas. The transceiver is configured to wirelessly communicate with the mobile device when the first detector detects that the mobile device is connected to the electronic device.
