    Abstract: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one cooperative device, an access point, and at least one non-cooperative device. The method includes steps of generating a matrix of at least 8 bits configured to register each instance of at least one of a clear-to-send frame and a request-to-send frame transmitted between the at least one cooperative device and the access point during a specified duration, calculating a cumulative distribution function based on the registered instances within the generated matrix for a probability of the presence of an aggressive transmission signal by the at least one non-cooperative device within a measurable vicinity of one or more of the cooperative device and the access point, and determining the presence of the aggressive transmission signal based on the calculated cumulative distribution function being greater than a predetermined threshold.

    Abstract: Systems and methods presented herein provide for improving communications when encountering aggressive communication systems. In one embodiment, a communication system includes a WAP operable to link a UE to a communication network via a communication protocol and a communications processor operable with the WAP to detect another communication system operating within a range of the WAP, and to determine that the other communication system is operating via another communication protocol that differs from the communication protocol of the communication network based on UEs in range of the WAP. The UEs are operable to communicate via both communication protocols. The communications processor queries the UEs in the range of the WAP to determine which of the UEs are communicating via the other communication protocol, and estimates a rate of successful communication with the UE via the WAP based on a number of UEs communicating via the other communication protocol.

    Abstract: Systems and methods presented herein provide for capacity sharing between wireless systems. One wireless telecommunications system includes a plurality of base stations and a Mobile Central Office (MCO) communicatively coupled to each of the base stations. Each base station is operable to handle a session from a wireless device and to handoff the session to another of the base stations when the wireless device moves into a range of the other wireless base station. The MCO is operable to detect capacity on a first of the base stations, to request capacity from another wireless system in response to detecting the capacity on the first base station, to acquire at least a portion of the requested capacity from the other wireless system, and to direct the wireless device to communicate via the capacity acquired from the other wireless system.

    Abstract: Systems and methods presented herein provide for altering communications of a LTE wireless communication system operating in an RF band with a conflicting WiFi system. In one embodiment, an LTE system includes a wireless base station operable to transmit downlink communications to a UE in the RF band and to receive uplink communications from the UE in the RF band. The LTE system also includes a processor operable to detect the uplink communications from the UE, to estimate a location of the UE based on the detected uplink communications, to determine a communication capability between the UE and the wireless base station based on the location of the UE, and to downgrade the downlink communications from the wireless base station to the UE based on the determined communication capability to avoid interference with the WiFi communication system.

    Abstract: Systems and methods presented herein provide for capacity sharing between wireless systems. In one embodiment, a scheduler is operable with a plurality of wireless base stations. Each base station is operable to digitize a frequency spectrum of radio communications from a plurality of user equipment (UEs). The scheduler communicatively couples to first and second Mobile Central Offices (MCOs). The scheduler processes the digitized frequency spectrums of the base stations, extracts radio communications of a first of the UEs from the digitized frequency spectrums of one or more of the base stations coupled to the first MCO, determines that a capacity of the first MCO has been exceeded, determines that a capacity of the second MCO is available, acquires at least a portion of the capacity of the second MCO, and handles a call of the first UE through the capacity acquired from the second MCO.

    Abstract: A multiple-input multiple-output (MIMO) capable system is contemplated. The communication system may include a signal processor configured to separate an input stream into multiple signal paths to facilitate simultaneous transport through a communication medium. The capability to simultaneously transmit multiples signal paths may be beneficial in order to maximize throughput and/or minimize expense.
