Abstract: A device, method, and computer-readable medium are provided for detecting and mitigating signal interference due to passive intermodulation at a base station. Generally, when antennas are configured to transmit at two or more different bands or frequencies, particular combinations of frequencies can introduce passive intermodulation at one of the corresponding receive bands or frequencies. Passive intermodulation is exacerbated, in some instances, due to the presence of non-linearities in the RF path. Embodiments can be configured to automatically detect the presence of passive intermodulation in one of the receive bands or frequencies and dynamically mitigate the affected receive signal to maintain optimal system performance.

Abstract: A wireless access point to dynamically controls power amplifiers. The wireless access point wirelessly exchanges media communications using a plurality of frequency bands. The wireless access point monitors an internal temperature in an enclosure and determines that the internal temperature is above a temperature threshold. The wireless access point monitors traffic loading on each of the plurality of frequency bands exchanging media communications and selects a frequency band with a low traffic level. The wireless access point redirects the media communications to a frequency band having a higher traffic loading level and disables a power amplifier associated with the selected frequency band having the low traffic loading level.

Abstract: Systems and methods for performing UE handover based on group delay variation include a base station (i) selecting a target neighbor sector from a plurality of neighbor sectors for the handover, where each neighbor sector has a group delay metric, and where the target neighbor sector is selected from the neighbor sectors based at least in part on each neighbor sector's group delay variation and (ii) initiating handover of the UE to the target neighbor sector. Some embodiments include creating a neighbor relations table (NRT) comprising at least some of the neighbor sectors, and prioritizing the NRT based on group delay and/or group delay variation. In some embodiments, selection of the target neighbor sector for the handover is additionally based on neighbor sector handover success rates and Reference Signal Receive Power (RSRP) values for neighbor sectors reported by the UE for which the handover is to be performed.

Abstract: A device, method, and computer-readable medium are provided for mitigating signal interference at a base station. Signal interference can be generated from subcomponent levels at a base station (e.g., electronic antenna motors) due to non-optimal designs or electric ground interferences. Generally, when power is provided to such subcomponent(s), a noise or harmonic can be inadvertently generated, falling into one of the operating bands of the base station, and negatively impacting system performance. As such, embodiments can be configured to dynamically ascertain a noise baseline associated with the base station, determine that one or more of the subcomponents are at fault for interfering with the base station operating band(s), and mitigate the interfering signal for a period that least impacts system performance.

Abstract: According to the present disclosure, a base station may be configured to serve a user equipment device (UE) over two or more beams using different modulation and coding schemes (MCSs) in response to determining that another base station is concurrently serving another UE at nearly the same location. For instance, a first base station may initially serve a first UE over two beams using the same MCS on both beams. The first base station may then determine that a second base station is serving a second UE at nearly the same location. And in response, the first base station may then change the MCS on at least one of the two beams so that the first base station then serves the first UE using different MCSs on the two beams. Serving the first UE with different MCSs concurrently on multiple beams may help to improve the first UE's reception.

Abstract: Systems, methods, and software described herein provide enhancements for monitoring communication data for multiple applications on a wireless device. In particular, a wireless access node is configured to monitor signal to noise data for a first frequency band from a second frequency band. When the signal to noise data meets noise criteria, the access point schedules observation periods in the first frequency band to determine intermodulation distortion for the first frequency band from the second frequency band. Based on the intermodulation distortion meeting distortion criteria, the access point schedules the second frequency band to transmit data only when the first frequency band is neither transmitting nor receiving data.

Abstract: Systems, methods, and computer-readable media for detecting cell site component faults are provided. An unmanned aerial vehicle may be utilized to collect heat signature information about remotely located cell towers. The heat signature information is analyzed to detect any anomalies at the remote cell site that may indicate an antenna, radio, or cable connector are malfunctioning or need repair, for example. When an anomaly is detected, an indication of the anomaly and information to identify one or more components that correspond to the anomaly are communicated.

Abstract: During a communication session, a filter in the RAN may filter signals sent over the communication pathway. When the filter filters signals sent over communication pathway, it may also cause some filter loss in the signals. The amount of the filter loss may vary as a function of frequency. Before the start of a communication session, the RAN may determine a filter loss for a given frequency. Because a higher filter loss indicates the RAN will transmit (or receive) a weaker signal, it may be undesirable to transmit signals to WCDs that are located a far distance from the RAN with frequencies having high filter losses. Thus, once the RAN has determined a filter loss for a given frequency, the RAN may reserve the given frequency for use in communication between the RAN and at least one WCD based on a distance between the WCD and the RAN.

Abstract: A machine for dispensing a freshly mixed cup of juice or other beverage made from concentrate mixed with water immediately prior to the dispensing, comprising a generally U-shaped water reservoir, the water in which is kept at an essentially constant level by means of a proximity switch interacting with a solenoid valve located in the principal water supply. Coils of a refrigerant unit are disposed in the reservoir to chill the water to a temperature above the freezing point, and one or more concentrate tanks are located between the arms of the U-shaped reservoir, so that the concentrate will be chilled to, and maintained at, a desired temperature. Modular pump units are utilized for pumping concentrate into a mixing chamber, with a power driven impeller utilized in the mixing chamber to effect a mixing of concentrate with a suitable quantity of water from the reservoir.
