The present disclosure relates to apparatus, systems, and methods for analyzing characteristics of entities of interest. In particular, the present disclosure provides a mechanism for analyzing information about entities of interest and for rating or scoring the entities of interest based on the analyzed information. The rating or the score of an entity of interest can sometimes be referred to as a placerank value of an entity of interest.

Apparatus and methods for providing enhanced coverage in a quasi-licensed wireless system using a reduced-cost base station apparatus. In one embodiment, the base station is configured to utilize quasi-licensed 3.55-3.70 GHz CBRS (Citizens Broadband Radio Service) GAA and PAL spectrum, and employs a power amplifier sharing arrangement in its transmitter chain(s), along with multi-sector antenna elements. A scheduling algorithm operative on the base station generates sector-specific weights which are used to allocate the shared power amplifier(s) between the different sectors. Advantageously, design and production costs of the base station are reduced through sharing of comparatively expensive amplifier and transmitter chain components, thereby allowing for commoditization of the base station for mass distribution.

In an aspect, a first network node may receive, from a second network node, one or more reference signals transmitted using one or more first polarizations known to the first network node, wherein the one or more reference signals are received having one or more second polarizations. The first network node may determine whether the one or more reference signals followed a line-of-sight (LOS) path between the first network node and the second network node based on a comparison of signal characteristics related to the one or more first polarizations and signal characteristics related to the one or more second polarizations.

A knowledge base of cell information can be built and made available to one or more mobile devices. A mobile device with access to this cell information may proactively perform a radio signal scan at a frequency of an expected cell(s) that is/are indicated in the cell information (e.g., if the expected cell is associated with a serving cell and/or with a geolocation that corresponds to the current Global Positioning System (GPS) location of the mobile device). After performing the radio signal scan, the mobile device may store measurement information (e.g., signal strength) about the expected cell(s) in local memory of the mobile device, and, upon receiving an instruction from the serving cell, the mobile device may access the stored measurement information from its local memory, and may send the measurement information to the requesting serving cell.
