Abstract: A device may receive a beamformed wireless signal from a base station. The device may perform a frequency conversion of the beamformed wireless signal to form a frequency converted signal after receiving the beamformed wireless signal. The device may perform, after performing the frequency conversion, processing related to at least one of: analyzing the frequency converted signal, scanning a channel associated with the frequency converted signal, or generating a map related to the frequency converted signal. The device may generate, after performing the processing, output related to at least one of: the analyzing the frequency converted signal, the scanning the channel, or the generating the map.

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.

Abstract: Methods and systems for adjacent channel leakage ratio (ACLR) measurement in a cellular network are provided by creating a measurement timing for a symbol or signal transmitted from a base station of the cellular network in an allocated frequency band, measuring power levels of the signal in the allocated frequency band based on the created measurement timing, and measuring power levels in adjacent bands based on the created measurement timing, and deriving the ACLR measurement from the measured power levels in the allocated frequency band and the measured power levels in the adjacent bands.
