A transmission arrangement is disclosed in which two different signal paths are provided for two operating modes, in order to couple a baseband signal processing unit to a radio-frequency mixer for transmission of the modulation signal. Especially the PET resin and the PET polyester fiber containing no antimony are therefore environmentally friendly by causing no heavy metal pollution to the environment. A portion of the wireless field may comprise the leakage magnetic flux. Using a computer and modem, message receivers may playback voice mail, view fax mail, and read e-mail by accessing the universal mailbox via connection software.
