Techniques are provided for enhancing continuity in service of a radio authorized to transmit in shared spectrum by setting a transmit expiry time based upon whether the radio must cease transmission when a dynamic incumbent user operates in the dynamic protection area (DPA) to avoid aggregate interference to a receiver of the dynamic incumbent user, in or about the DPA, exceeding a threshold interference level.

Systems and methods for increasing continuity of communications service

Methods, systems, and computer readable media described herein can be operable to provide a 6 GHz backhaul within a premise. Adapters may facilitate a conversion of communications between one or more local area networks and one or more wide area networks. A 6 GHz backhaul may be used by one or more access points to support various wireless services having unique or differing operational and bandwidth requirements. A 6 GHz backhaul may be used to pass communications between an adapter and a network interface device and/or between the adapter and one or more access points.

Wireless backbone and structured wireless

Methods, systems, and computer readable media described herein can be operable to facilitate location determination, communications with an AFC system, configuring operational parameters in response to an identification of active 6 GHz paths, and timing distribution and low-latency services. Methods, systems, and computer readable media are described herein for implementing and improving use of automated frequency coordination (AFC), operational deployment of the 6 GHz band for unlicensed devices, and use of the 6 GHz band for low-latency services, timing distribution, and QoS.

Automated frequency coordination and device location awareness

A system for ESC protection includes a spectrum access system (SAS) configured to allocate a frequency band in the system and at least one Citizens Broadband Radio Service device (CBSD) communicatively coupled to the SAS and configured to provide wireless service to UEs. The system also includes at least one ESC communicatively coupled to the SAS and configured to detect RADAR signals from offshore RADAR devices. The SAS is configured to assign grants to the at least one CBSD such that the aggregate signal energy received at the ESC does not cross an overload threshold, as calculated by the SAS. The ESC is configured to detect an aggregate signal energy received at the ESC, and trigger, in response to the aggregate signal energy exceeding the overload threshold, an operation that suspends transmission of at least one CBSD or moves at least one CBSD to a different frequency channel.

Mechanism for environmental sensing capability protection

In one embodiment, a method is provided. The method comprises: setting a first voltage level provided to a cable; operating a radio, coupled to the cable, with constant power consumption; measuring a first current level provided to the cable; setting a second voltage level provided to the cable; measuring a second current level provided to the cable; and determining a first resistance of the cable using the first and second voltage and current levels.

Methods and apparatuses for determining cable resistance

Apparatuses for determining cable resistance

Certain aspects are directed to an interceptor system for characterizing digital data communicated between certain points in a telecommunication system. The interceptor system includes an interface device and a processing device. The interface device can retrieve data from at least one communication link between a radio frequency processing unit and a baseband processing unit of a telecommunication system. The data includes digital data communicated between the radio frequency processing unit and the baseband processing unit. The processing device can determine an interface link protocol for communicating with terminal equipment via the telecommunication system. The interface link protocol can be determined based on an organization of the data retrieved from the communication link.

Interceptor system for characterizing digital data in telecommunication system

A method for detecting interference in a wireless system is disclosed. The method includes receiving an uplink signal at a remote radio head in a distributed base station, passing the uplink signal from the remote radio head to a baseband unit over a front-haul communication link as baseband IQ data, and intercepting the baseband IQ data at a tester coupled between the remote radio head and the baseband unit. Processing of the IQ data is performed to determine whether an interfering signal is present in the uplink signal.

Interference detection and identification in wireless network from RF or digitized signal

A passive intermodulation (PIM) tester is provided. The PIM tester includes at least one interface to couple the tester to a front-haul communication link used for communicating front-haul data to a remote radio head (RRH) having one or more antenna ports. The PIM tester includes a programmable processor, coupled to the interface, configured to execute software, wherein the software is operable to cause the tester to do the following: identify at least one tone in at least one downlink band of the remote radio head, wherein potential PIM products may appear in at least one uplink band of the remote radio head in response to the identified at least one tone; inject the identified at least one tone in the at least one downlink band of the remote radio head; and monitor the at least one uplink band for the potential PIM products from the injected at least one tone.

Passive intermodulation (PIM) testing in distributed base transceiver station architecture

A method for detecting the presence of a signal in a frequency spectrum is provided. The method includes receiving the frequency spectrum. The power spectral density of the received frequency spectrum is estimated. A plurality of frequency bins are segmented for the frequency spectrum based on the estimated power spectral density. For segments with an estimated power spectral density above a first threshold, a radar spectral signature matching algorithm is applied to detect the presence of the signal and for segments with a power estimate below the first threshold and above a second threshold, additional techniques are applied to detect the presence of the signal.

Detecting Federal Incumbent Radar (FIR) signal

The present disclosure describes various embodiments for detecting and/or localizing a passive intermodulation distortion signal in a radio frequency system having multiple transmit and/or receive paths.

System and method for passive intermodulation source localization

A method for diminishing passive intermodulation (PIM) is provided. The method comprises: upsampling an uplink baseband modulated signal; upsampling a downlink baseband modulated signal; determining a time delay for the upsampled downlink baseband modulated signal; time delaying the upsampled downlink baseband modulated signal by the determined time delay; estimating a third order PIM distortion (PIMD) product by filtering the time delayed, upsampled downlink baseband modulated signal with a third order power series kernel; generating a first filtered signal by subtracting the estimated third order PIMD product from the upsampled downlink baseband modulated signal; estimating a Nth order PIMD product by filtering the time delayed, upsampled downlink baseband modulated signal with a Nth order power series kernel; generating a nth filtered signal by subtracting the estimated Nth order PIMD product from the n&#x2212;1th filtered signal; and downsampling the nth filtered signal.
