Patent number: 9781685Abstract: Both uplink spectral efficiency and downlink spectral efficiency are improved through adjustments made to various parameters that would otherwise be treated as static type parameters. Variations in respective performance of two or more cells can be considered during the adjustment. Further, variations of respective cell performance based on time of day/week are considered and compensated for through various adjustments. Such timely adaptations are applied in order to improve the performance of each cell, during each time of day/week.Type: GrantFiled: November 21, 2013Date of Patent: October 3, 2017Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Ernest Tsui, Srikanth Hariharan, Vibhav Kapnadak

Patent number: 9768812Abstract: A passive intermodulation detection system is provided to remotely identify passive intermodulation at a base station site and diagnose the type of intermodulation and location of the non-linearity that is the source of the passive intermodulation. The passive intermodulation detection system can generate a test signal in a first band that is transmitted by an antenna. Another antenna can receive a signal in another band, and the passive intermodulation detection system can analyze the received signal to determine whether an intermodulation product due to a non-linearity is present. Based on the type of intermodulation product, period, order, frequency, and etc, the type and location of the non-linearity can be identified and canceled via a passive intermodulation canceling mechanism.Type: GrantFiled: June 10, 2016Date of Patent: September 19, 2017Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Ernest Tsui, Paul Maxwell, Vibhav Kapnadak

Patent number: 9392473Abstract: During scheduled or unscheduled wireless communication outage, restoration of crucial or critical cell site devices and/or base station device are prioritized. The system filters current key performance indicator values and historical key performance indicator values for a reference cell device to produce a filtered key performance indicator metric for the reference cell device, filters statistical data to produce filtered statistical data representing a filtered statistic for the reference cell device, determines a weighting factor for the reference cell device, and displays of a ranking score determined as a function of the weighting factor, the filtered statistic data, and the filtered key performance indicator metric. The ranking score provides an ordering that can be used to restore critical cell site devices and/or base station devices.Type: GrantFiled: September 16, 2015Date of Patent: July 12, 2016Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Vibhav Kapnadak, Zhi Li

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.Type: ApplicationFiled: December 6, 2012Publication date: June 12, 2014Applicants: AT&T INTELLECTUAL PROPERTY I, L.P., AT&T MOBILITY II LLCInventors: Fereidoun Tafreshi, Srikanth Hariharan, Vibhav Kapnadak, Hyun Ok Lee, Xiaojun Tang
