Hi,
Results from drive test conducted at the same time for scan & active (voice) mode.
But the values for RSCP, RSSI & Ec/Io vary significantly.
- RSCP is higher for scan mode (understandable as active mode may have missing nbrs, overshooters, handover issues)
- RSSI is higher for scan mode ( shouldn't it be the same for scan and active modes ?)
- Ec/Io is higher for active mode (shouldn't this be lower ? should we check scan Ec/Io or active Ec/Io for optimization ?)
Distribution is as below:
