Abstract: According to examples, NR and LTE signal concurrent testing may include ascertaining LTE synchronization data associated with an LTE signal, and ascertaining NR synchronization data associated with an NR signal. The NR and LTE signal concurrent testing may further include performing, for the LTE synchronization data, LTE analysis, and performing, for the NR synchronization data, NR analysis. Based on the LTE analysis and the NR analysis, a mufti-path profile of the LTE signal and the NR signal may be determined.

Abstract: A test device may be a portable test device that can perform over the air measurements to determine synchronization errors between clusters in a cellular network. The test device can generate a graphical user interface that can show a map of the boundary area between clusters, locations of base stations hi the boundary area, locations where over the air measurements were taken by the test device, an indication of whether cells are in synchronization for each measurement location, and a table of actual measurements and derived parameters pertaining to cell phase synchronization, interference and other performance metrics.
