Abstract
A cabinet capable of attenuating or blocking wireless signals contains, a medical device, such as an AED, an internal directional antenna mounted to an internal surface of the cabinet, an external omnidirectional antenna mounted to an external surface of the cabinet, and an electrical connection between the internal directional antenna and the external omnidirectional antenna. The internal and external antennas are configured to transmit wireless signals at particular frequencies and to receive wireless signals at the particular frequencies. The internal antenna is a high gain directional antenna, and the external antenna is a lower gain omnidirectional antenna.
Claims15
A system, comprising:
- a medical device configured to be located within a cabinet capable of attenuating or blocking wireless signal transmission, the medical device comprising a device antenna and being configured to communicate wireless signals at one or more particular frequencies using the device antenna;
- an internal directional antenna mounted to an internal surface of a window of a door of the cabinet, the internal directional antenna configured to transmit wireless signals at the one or more particular frequencies and to receive wireless signals at the one or more particular frequencies;
- an external omnidirectional antenna mounted to an external surface of the cabinet, the external omnidirectional antenna configured to transmit wireless signals at the one or more particular frequencies and to receive wireless signals at the one or more particular frequencies;
- and
- an electrical connection between the internal directional antenna and the external omnidirectional antenna, wherein the electrical connection is routed through a hinge area of the door of the cabinet such that the electrical connection does not interfere with removal of the medical device from the cabinet,
- wherein the system when deployed is configured such that the internal directional antenna is operative to receive a first wireless signal from the medical device, a first electrical signal based on the first wireless signal is provided via the electrical connection to the external omnidirectional antenna, and a second wireless signal based on the first electrical signal is radiated by the external omnidirectional antenna, and
- wherein the internal directional antenna is mounted such that the device antenna of the medical device is aligned with a directional antenna pattern of the internal directional antenna when the medical device is located within the cabinet.

A system, comprising:
- a cabinet comprising a door and a door hinge area, wherein the door comprises a window;
- a medical device configured to be located within the cabinet, the medical device comprising a device antenna and being configured to communicate wireless signals at one or more particular frequencies using the device antenna;
- an internal directional antenna mounted to an internal surface of the window of the door of the cabinet, the internal directional antenna configured to transmit wireless signals at the one or more particular frequencies and to receive wireless signals at the one or more particular frequencies;
- an external omnidirectional antenna mounted to an external surface of the cabinet, the external omnidirectional antenna configured to transmit wireless signals at the one or more particular frequencies and to receive wireless signals at the one or more particular frequencies;
- an electrical connection between the internal directional antenna and the external omnidirectional antenna, wherein the electrical connection is routed through the door hinge area such that the electrical connection does not interfere with removal of the medical device from the cabinet;
- and
- an external wireless access point,
- wherein the system when deployed is configured such that the internal directional antenna is operative to receive a first wireless signal from the medical device and to provide a first electrical signal based on the first wireless signal via the electrical connection to the external omnidirectional antenna, and to radiate a second wireless signal based on the first electrical signal from the external omnidirectional antenna, wherein the second wireless signal is received by the external wireless access point, and
- wherein the internal directional antenna is mounted such that the device antenna of the medical device is aligned with a directional antenna pattern of the internal directional antenna when the medical device is located within the cabinet.
