This KPI measures system performance. Since the KPI is measured by the RBS, it does not include time when the RBS is down, i.e. node restart time is excluded.

The length of time in seconds that a cell is available for service is defined as cell availability. Cell availability for a cluster of M number of cells during N reporting periods can be calculated using the following formula. The counters are on cell level.
