Abstract: Systems and methods for cellular network anomaly detection using spatially aggregated data are provided. Some methods can include identifying data signals at multiple, non-continuous times from a plurality of geographic regions, identifying a power value for each of the data signals, and when the power value for a first of the data signals corresponding to a first of the plurality of geographic regions is higher than a second value, identifying the first of the plurality of geographic regions as a possible location of external interference in a LTE downlink communication channel, a TD-LTE uplink communication channel, or a FD-LTE uplink communication channel.

Abstract: Embodiments disclosed herein include systems and methods for locating all synchronization signal blocks on a 5G new radio channel. Such systems and methods can include measuring downlink signal energy over a bandwidth of the 5G new radio channel to identify a center frequency of a signal broadcast on the 5G new radio channel, processing the signal at the center frequency of the signal to identify a first of a plurality of synchronization signal blocks and global OFDM symbol boundaries for the wireless radio channel, and using the global OFDM symbol boundaries for all raster frequencies of the 5G new radio channel to identify remaining ones of the plurality of synchronization signal blocks.
