Abstract: Some embodiments include systems and methods for establishing incident communications networks. The system can include an incident controller, a communications resource database that stores communications resources information, and a marshalling rules module that stores a set of marshalling rules. The incident controller can use a marshalling rule to identify and select the communications resources to be marshaled into the incident communications network based on an incident trigger. Upon receipt of an incident trigger, the incident controller is configured to establish the incident communications network by obtaining a marshalling rule based on the incident trigger. The incident controller marshals communications resources based on the marshalling rule and the communications resources determined to be available. Information sources can either provide an incident trigger (e.g., a hurricane warning) or provide data to be analyzed to determine an incident trigger.

Abstract: A serving mobile location center (SMLC) receives a position request concerning a mobile-of-interest (MOI) operating in a discontinuous transmission (DTX) mode, and in response a wireless location system (WLS) is tasked to locate the MOI. A plurality of location measurement units (LMUs) are instructed to receive and digitize radio frequency (RF) energy. At the LMUs, a signal of interest is received and cross-correlated with a known training sequence to produce a received detection metric. The detection metric is weighted to favor the MOI even in the presence of interference from other mobile devices. The SMLC selects the LMU with the best weighted detection metric as a reference site and selects two or more LMUs with lesser weighted detection metrics above a threshold as co-operating sites. The received signal of interest is demodulated and demodulated data are distributed to the co-operating sites.

Abstract: A method for controlling an adjustable gain in an amplifier having an output power level and an adjustable gain is disclosed. The method includes an enhancement to a conventional Automatic Gain Control (AGC) function that distinguishes between a signal caused by oscillation and a signal that actually appears in the amplifier's passband. The method also controls unwanted and out of control amplifier oscillation using an iterative correlation process. The method prevents gain “hunting” if the output signal level is near the “set point” of the maximum permitted output level by implementing some degree of Hysteresis. The correlation process is performed by tracking a specified number of alternating gain increase/decrease cycles. If in any cycle the gain is not changed, or is changed in the same direction as in the previous cycle, the correlator is reset and the process begins again.

Abstract: Two or more sectors of a coverage area of a wireless communication system may be linked together to form a wide area network. Each sector is associated with at least one radiation pattern carrying information, and the sectors forming the wide area network share at least some of the same information. One base station modem used to encode and decode information may be coupled to two or more radio transceivers, wherein each transceiver is associated with a different sector. In this manner, two or more differently geographically disposed sectors essentially function as one wide area network, in that the multiple sectors are served by one base station modem. The number of sectors that are selected to be serviced by a particular base station modem may be based at least in part on one or more of a capacity demand and a topological distribution of subscriber stations in at least a portion of the coverage area.

Abstract: Latitude and longitude information within a wireless navigation and information system (200) is transmitted from route planning equipment (207) to a base site (201). A translator (203) converts each reference point from an absolute coordinate to a relative coordinate by subtracting a reference geographic location from each absolute coordinate (350). The base site (201) then sends a message comprising the relative coordinates for each reference point to the remote unit (213). Finally, the remote unit (213) utilizes the reference geographic location and calculates absolute coordinates for each reference point and passes this information to any navigation equipment (705) that is coupled to the remote unit (213). Broadcasting only the relative coordinates of each reference point to the remote unit (213) allows reference points to be transmitted to the remote unit (213) in a shorter length message than with prior-art methods.

Abstract: Sequential data transmission by a plurality of communication units may be achieved in a communication system by using an accurate external clock and transmitting at predetermined time intervals or time slots. By using a GPS clock signal as the external clock, a communication system may determine a cycle time and duration of time slots such that each communication unit is allocated a time slot for data transmission. This approach eliminates the need for polling of communication units and substantially reduces data congestion on control channels of the communication system.

Abstract: A console interface for a trunked communication system is disclosed wherein unique interface modules are coupled to the central controller and console network to establish communication therebetween. A console interface constructed and arranged to transceive trunking channel call information couples the dispatcher console to the console network thereby allowing the dispatcher to interact with the trunked system.
