Filed:

Dec 9, 2005

Appl. No.:

11/299106

Inventors:

Carl E. Fabian - Miami FL, US
Frank O'Neill - Boulder CO, US

International Classification:

G08B 13/14

US Classification:

3405721, 3405724, 3405681

Abstract:

Provided is a detector system for detecting a plurality of items each having at least one RFID tag attached thereto. The detector system may include a presence detector and/or a message detector. The presence detector may include a signal reader which receives modulated carrier frequencies from the RFID tags during a predetermined response time period for comparison to a reference level. The signal reader may be configured as a power integrator or a constellation discriminator. The power integrator sums the power contained in signals transmitted by the RFID tags by integration for comparison to an environmental noise level measurement taken during a quiet period. For the constellation discriminator, bits contained in the modulating message are compared to the bit pattern of a predetermined reference constellation. The detector system may be configured as a 3-state detector which combines the presence detector with a message detector that indicates the identification code of the RFID tags.

Appl. No.:

11/289877

Inventors:

Frank P. O'Neill - Boulder CO, US

International Classification:

H04B 7/15

US Classification:

455 111, 155 121, 155 131, 155 15

Abstract:

A repeater system combines co-located antennas, an intentional imbalance in signal amplification between downlink and uplink, stability management and an amplification indicator to create a user-installed solution to co-channel interference within cellular systems, in strong signal environments such as elevated locations or high-rise building. The invention may be particularly relevant to cellular systems, such as CDMA, that allow limited imbalance between uplink and downlink path losses, thus enabling the design of an inexpensive repeater with a weaker or non-existent uplink, and which creates moderate signal amplification for selected line-of-sight signals, defeating co-channel interference over a small area. The difference in signal amplification on the downlink and uplink is maintained at a level below the capacity of the system to support imbalance, guaranteeing reliable cellular calls.

Abstract:

A repeater system combines co-located antennas, limited and controlled downlink signal amplification, stability management and an amplification indicator to create a user-installed solution to co-channel interference within cellular systems, in strong signal environments such as elevated locations or high-rise building. The invention may be particularly relevant to cellular systems, such as CDMA, that allow limited imbalance between uplink and downlink path losses, thus enabling the design of an inexpensive downlink repeater which creates moderate signal amplification for selected line-of-sight signals, defeating co-channel interference over a small area.
