    Abstract: A device may receive small cell data associated with a small cell, wherein the small cell data includes small cell location data and a small cell barometric pressure reading. The device may identify a calibration user device connected to the small cell and may receive, from the calibration user device, a user device barometric pressure reading. The device may calibrate, based on the user device barometric pressure reading, the small cell barometric pressure reading to obtain a calibrated small cell barometric pressure reading. The device may identify a reference weather station and may receive, from the reference weather station, weather station data, wherein the weather station data includes a weather station barometric pressure reading, and a weather station altitude that indicates an altitude of the reference weather station. The device may determine a small cell altitude based on the calibrated small cell barometric pressure reading and the weather station data.

    Abstract: A base station may obtain channel usage information identifying usage of one or more unlicensed radio frequency (RF) spectrum bands. The base station may select a selected band, of the one or more unlicensed RF spectrum bands, based on the channel usage information. The base station may select one or more RF channels, of multiple RF channels included in the selected band, based on a congestion value of the selected band. The congestion value may be determined based on values of the channel usage information corresponding to the selected band. The selected RF channel may include an impaired RF channel that may not permit full bandwidth utilization due to constraints. The base station may communicate with user equipment via the one or more RF channels of the selected band.

    Abstract: An improved lawful intercept (LI) infrastructure is described. In response to a valid LI provisioning request, a subscriber management component statically allocates a user equipment (UE) subject to the LI provisioning request to an edge location comprising a high-speed gateway and a Mediation and Delivery Function (MDF), which coordinates the delivery of intercepted communications. The subscriber management component maintains this allocation for the life of the LI provisioning request and reverses the UE to a dynamic gateway allocation scheme when the LI provisioning request ends. As a result, only a subset of edge locations must be equipped with MDFs, and the handover is transparent to the UE.
