Expandable in-wall antenna for a security system control unit
View Patent ↗The present disclosure relates to an expandable antenna for a security system that is installed within a wall. The security system may include a control unit. The control unit may include a casing that houses one or more internal components of the control unit and a radio-frequency (RF) communication module that is situated within the casing. The RF communication module includes an antenna connected that is exposed to the exterior of the casing. An expandable antenna connects to the antenna connector. The expandable antenna is fit through an aperture in a wall and is then expanded to an enlarged size within the gap of the wall.
1. A control unit for a security system, the control unit comprising:
a casing for housing one or more internal components of the control unit for a security system;
at least one radio-frequency communication module situated within the casing of the control unit;
at least one antenna connector for the security system; and
an expandable antenna external to the casing of the control unit, configured to connect to the antenna connector, the expandable antenna fitting through an aperture in a wall to which the control unit is mounted and expanding to an enlarged size within a gap of the wall.
2. The control unit of claim 1 , further comprising a second radio-frequency communication module, the second radio-frequency communication module connecting to a second expandable antenna fitting within a second aperture in the wall to which the control unit is mounted.
3. The control unit of claim 1 , wherein the radio-frequency communication module is a Global System for Mobile Communications (GSM) communication module.
4. The control unit of claim 1 , wherein the expandable antenna connects to a cable component that communicatively connects the expandable antenna to the antenna connector.
5. The control unit of claim 4 , further comprising a stopper component at a proximal end of the cable component opposite the expandable antenna, the stopper component preventing the proximal end of the cable component from passing through the aperture in the wall.
6. The control unit of claim 1 , wherein the expandable antenna is a loop antenna comprising an expander configured to expand the loop antenna from an elongated shape to a substantially circular loop shape.
7. The control unit of claim 1 , wherein the expandable antenna is a dipole antenna comprising an expander that changes the orientation of a first pole of the dipole antenna to a second pole of the dipole antenna from substantially parallel orientation to a substantially aligned orientation.
8. A security system comprising:
a plurality of sensors communicatively connected to a control unit for the security system;
the control unit comprising:
a casing housing one or more internal components of the control unit for a security system;
a Global System for Mobile Communications (GSM) communication module situated within the casing of the control unit, the GSM communication module comprising an antenna connector accessible from an exterior of the casing of the control unit;
an expandable in-wall antenna configured to connect to the antenna connector, the expandable in-wall antenna fitting within an aperture in the wall while in a compact state and expanding to an expanded state inside the wall.
9. The security system of claim 8 , further comprising the GSM communication module communicatively connecting the control panel with a remote server over a GSM network.
10. The security system of claim 8 , wherein the control unit further comprises a Z-Wave communication module that communicates with one or more electronic devices according to the Z-Wave communications protocol, the Z-Wave communication module further comprising a Z-Wave antenna situated within the case of the control unit.
11. The security system of claim 8 , wherein the control unit further comprises a Z-Wave communication module that communicates with one or more electronic devices according to the Z-Wave communications protocol, the Z-Wave communication module further comprising an expandable in-wall Z-Wave antenna that connects to a Z-Wave antenna connector of the Z-Wave communications module, the expandable in-wall Z-Wave antenna fitting within a second aperture in the wall while in the compact state and expanding to the expanded state inside the wall.
12. The security system of claim 8 , wherein the expandable in-wall antenna is a loop antenna.
13. The security system of claim 8 , wherein the expandable in-wall antenna is a dipole antenna.
14. The security system of claim 8 , wherein the expandable in-wall antenna is a telescoping monopole antenna.
15. The security system of claim 8 , wherein the expandable in-wall antenna comprises an expander connected to the expandable in-wall antenna that, in response to being engaged, expands the expandable in-wall antenna from the compact state to the expanded state.
16. A method comprising:
creating an aperture in an exterior section of a wall;
inserting an antenna in a compact state into the aperture such that the antenna is behind the exterior section of the wall;
following inserting the antenna into the aperture, expanding the antenna from the compact state to an expanded state; and
connecting the antenna to an antenna connector of a control unit for a security system.
17. The method of claim 16 , further comprising mounting the control unit to the exterior section of the wall.
18. The method of claim 16 , further comprising establishing a connection between the control unit and a remote server using a Global System for Mobile Communications (GSM) connection, the GSM connection established using the antenna.
19. The method of claim 16 , wherein creating the aperture comprises creating an aperture having a size smaller than a size of a stopper component of the antenna.
20. The method of claim 19 , further comprising removing the stopper component.
