ABSTRACT:
A through-the-window coaxial coupler coaxially couples Radio Frequency (RF) signals between the inside and outside surfaces of a window. The through-the-window coaxial coupler includes an inside portion that mounts on the inside surface of a window, and an outside portion that mounts on the outside surface of the window and couples to an outside antenna. An inside electronic package couples to the inside portion of the through-the-window coaxial coupler, and is located adjacent the inside portion and remote from a radiotelephone. The inside electronic package includes a receive amplifier that amplifies RF signals that are received from the outside antenna via the through-the-window coaxial coupler and that provides the RF signals so amplified to the radiotelephone. In another embodiment, the inside electronic package may include a wireless transceiver and that wirelessly transmits and receives signals to and from a radiotelephone. Thus, only power may need to be supplied to the electronic package, but signal and/or connections may be provided to the radiotelephone using wireless communications. One such wireless communications protocol that may be used is the well known "Bluetooth" protocol that defines a universal radio interface in the 2.45 GHz frequency band that enables wireless electronic devices to connect and communicate wirelessly via short-range, ad hoc networks.
