Abstract

An In-Building Communications system is disclosed which permits communication in tunnels, underground parking garages, tall buildings such as skyscrapers, buildings having thick walls of concrete or metal, and/or any building which has communication dead zones due to electromagnetic shielding. The invention includes a portable bi-directional amplifier (BDA) system, an outdoor antenna system attached to the building or independently mountable, an indoor antenna system attached to the building or independently mountable inside the building, and a standardized, In-Building Communications (IBC) interface box affixed preferably to the exterior of the building. The interface box communicates with antenna systems attached to the building. The fire department or other emergency response personnel carry portable outdoor and indoor antenna systems and a portable, lithium-ion battery powered, bi-directional amplifier (BDA) system which may be connected to the building during an event such as a fire, earthquake, or an act of terrorism or whenever radio coverage enhancement is required. The portable BDA system is simply connected to the standardized, IBC interface box and powered thus restoring communications within.

Claims

1. A vehicle borne transportable radio coverage enhancement system comprising:

an amplifier kit;

an antenna kit;

a vehicle;

said vehicle has an amplifier kit bin;

said amplifier kit rests within said amplifier kit bin;

said amplifier kit is removably attached to said vehicle by a first removable retention strap;

said vehicle has an antenna kit mounting platform;

said antenna kit rests upon said antenna kit mounting platform;

said antenna kit is removably attached to said vehicle by a second removable retention strap;

said antenna kit has an outdoor antenna that is connected via an outdoor antenna cable to an outdoor antenna connector of said amplifier kit, and

said antenna kit has an indoor antenna that is connected via an indoor antenna cable to an indoor antenna connector of said amplifier kit.

2. A vehicle borne transportable radio coverage enhancement system as claimed in claim 1 wherein said antenna kit mounting platform is a horizontal surface that can rotate about a vertical axis achieving a preferred orientation when said second removable retention strap is removed.

3. A vehicle borne transportable radio coverage enhancement system as claimed in claim 1 wherein said amplifier kit bin comprises a horizontal, rectangular bottom surface and low-profile vertical side walls.

4. A vehicle borne transportable radio coverage enhancement system as claimed in claim 1 wherein:

said antenna kit comprises a tripod;

said tripod has a vertically telescoping center mast to which said outdoor antenna is adjustably attached, and

said indoor antenna is removably attached to said tripod.

5. A vehicle borne transportable radio coverage enhancement system as claimed in claim 2 wherein:

said antenna kit comprises an organizer for said indoor antenna cable, and

said organizer has a cable dispenser that dispenses cable horizontally in a direction aligned with said preferred orientation.

6. A method for deploying a vehicle borne radio coverage enhancement system comprising the steps of:

parking a vehicle in proximity to a structure that requires radio coverage enhancement;

removing a retention strap from a vehicle borne antenna kit;

rotating said antenna kit to orient an indoor antenna cable dispenser toward a point of entry into said structure;

adjusting a directional outdoor antenna attached to a telescoping, rotatable mast to point in the direction of a donor repeater site;

enabling a vehicle borne amplifier;

removing an indoor antenna from said antenna kit;

routing an indoor antenna into said structure simultaneously dispensing said indoor antenna cable, and

placing said indoor antenna in a position within said structure central to an area requiring radio coverage enhancement.

7. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 wherein said directional outdoor antenna is a Yagi antenna.

8. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 wherein said indoor antenna is an omni directional antenna.

9. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 further comprising the step of:

replacing said retention strap securing said vehicle borne outdoor antenna kit preserving said indoor antenna cable dispenser'"'"'s rotational orientation and said directional outdoor antenna'"'"'s pointing direction.

10. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 wherein said step of enabling a vehicle borne amplifier comprises a step of delaying a programmable time before said amplifier begins radio frequency transmission.

11. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 wherein said vehicle comprises a compass and said step of adjusting a directional outdoor antenna comprises using said vehicle compass.

12. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 wherein said vehicle comprises a GPS receiver and said step of adjusting a directional outdoor antenna comprises using said vehicle GPS receiver.

13. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 6 further comprising the step of:

powering said vehicle borne amplifier from batteries internal to said amplifier, and

recharging said internal batteries using power from said vehicle electrical system.

14. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 13 wherein said batteries are lithium ion batteries.

15. A method for deploying a vehicle borne radio coverage enhancement system as claimed in claim 13 wherein said batteries are lead acid batteries.
