Abstract: RF tagging system (10) has a plurality of resonant circuits (13) on a tag (12). When the tag (12) enters a detection zone (14), the system determines the resonant frequencies of each of the resonant circuits (13) and produces a corresponding code. Preferably, resonant frequency detection is implemented by simultaneously radiating signals at each possible resonant frequency for the tag circuits (13). The system is useful for coding any articles such as baggage or production inventory. Preferably, the radiated signals are phase shifted during the detection process, and signals received by receiver antennas, besides transmitter signals, may be monitored to improve the reliability of detecting the resonant circuits (13). Also, a preferred step adjustment configuration for capacitive metalizations (106, 110) of the resonant circuits is described. For radiating signals into the detection zone (14), focused beam antennas (201) may be used such that each resonant circuit location on the tag can be separately monitored. Also, an apparatus (300) for producing customized resonant circuit tags in accordance with a specified input code is described.

Abstract: In a wireless private branch exchange (11), communication network (10), a method and apparatus are offered for identifying network communication resources. The method includes the steps of measuring a signal quality factor of a channel of a selected spectrum and comparing the measured values with a threshold value. The method further includes the step of selecting channels, exceeding the threshold, as network communication resources. The selected spectrum is that also used by a local cellular communication network. Where scanning determines that a channel is not used by the cellular system then use is permitted with the private system.

Abstract: A cellular cordless telephone (101) may receive cellular telephone calls via a cellular telephone system (103) and receive telephone calls on a system having a limited radio coverage area (113, 115). To reduce the amount of time spent in monitoring the sub-data channel of the limited coverage area system, a timing signal is generated which represents the period of time spent monitoring the radio channel (803). During the monitoring, a predetermined number of data words transmitted on the limited radio coverage area radio channel system are received. When a first received data word is detected (811), an allowed monitoring time value is adjusted to be the sum of the value of the timing signal and the product of a determined number of received words to be detected and the time required for each word (823). This adjusted value of the monitoring time value is compared to the value of the timing signal (825) and when the adjusted monitoring time value equals or exceeds the timing signal value, the monitoring of the radio channel ceases (825).

Abstract: An intelligent repeater (101) is used to control trunked communications at a trunked communication site in a trunked communications system. The intelligent repeater (101) transceives and signal processes radio frequency signals. The intelligent repeater (101) also processes and stores control information. The control information and processed signals are interfaced (109, 110, and 111) directly to an external communication network (117, 118, and 119), without use of a separate central controller for the trunked communication site or system.

Abstract: A radio communication system controller embodies the present invention by providing extended use (306) of a communication resource (106) to a plurality of communication units. The inventive method includes the steps of assigning (402) a first communication resource to a first communication unit, and then temporarily configuring (406) the assigned communication resource as a reserved resource. The controller then receives (408), from a second communication unit, a request to transmit a second communication on the assigned communication resource. Lastly, the controller re-configures (412) the assigned communication resource to allow transmission of the second communication on the assigned communication resource.
