Evaluation method and device

The invention discloses an evaluation method and device, relates to the technical field of communication, and is used for improving the accuracy of evaluating the coverage capability of a 5G network, and the method comprises the steps: determining the coverage range of a preset cell, and dividing the coverage range into a plurality of grids; determining a plurality of target candidate grids from the plurality of grids, the target candidate grids satisfying a preset condition: the first signal quality of the target candidate grids is less than a first threshold, or the second signal quality of the target candidate grids is less than a second threshold; the first signal quality and the second signal quality belong to different network types; multiple target grids are determined from the multiple target candidate grids, each target grid corresponds to one grid type, the distance between any two grids in each grid type is smaller than or equal to a third threshold value, and the number of the target grids in each
