Abstract: Aspects of the subject disclosure may include, for example, a system that provides for obtaining, by a server comprising a processor, network parameter data from an eNodeB of a wireless network. The server can determine a predicted bandwidth for a group of end user devices in a coverage area of the eNodeB according to the network parameter data. The server can receive, from an end user device of the group of end user devices, a request for the predicted bandwidth. The server can provide the predicted bandwidth to the end user device. The providing of the predicted bandwidth enables the end user device to provide a video chunk request to a content server that is based on a selected chunk delivery schedule and facilitates streaming of video content to the end user device from the content server. Other embodiments are disclosed.

Abstract: Systems and methods for overshooting cell device detection for application to self optimizing network algorithms are disclosed herein. The system ranks neighbor relationships between first, second, and third cell devices in a cellular network, based on handover statistics directly received from the cellular network. The system thereafter identifies one of the second cell device or the third cell device as an outlier neighbor cell device based on a ranking of the neighbor relationships and identifies, as a function of an azimuth direction and a distance between respective cell devices of a group of screened cell devices, an overshooting cell device that propagates a transmitted radio frequency signal causing interference to a cell device included in the group of screened cell devices.

Abstract: Cluster-based optimization of antenna tilts in a wireless network and other related aspects are presented herein. A screening component can receive information indicating wireless conditions of respective wireless access points of a geographical region, select, based on a performance criterion, an access point of the respective wireless access points, and group the access point and an other access point of the respective wireless access points into a representation of a cluster of access points. Further, an optimization component can derive antenna tilt values for respective access points of the cluster of the access points in response to a simulation of an application of the antenna tilt values to the respective access points. Furthermore, an implementation component can direct the antenna tilt values to respective components of the respective access points.
