What is GoS (Grade of Service)?

During the busiest hour, the Grade of service (GOS) is an estimation of the capacity of versatile endorsers to access a cellular framework. GOS is normally determined as the likelihood that a cell is blocked, or call encountering a delay greater than the given queuing time. Grade of service might be seen autonomously according to the point of view of approaching versus outgoing calls, and is not really equivalent toward every path or between various source-destination pairs.
