  26. 26. 2626 issue 11/09 TECHCOM Consulting  TECHCOM.DE Copyright © All rights reserved Radio Performance Optimisation Monitoring during SHO (Event 1A – best active cell) Conclusion: Shift filter values for E1A Ec/Io requirements (see also chapter SHO) This will improve RSCP (coverage due to MDC/MRC & SHO gain) DYLO already impacts too early NRT service activation at cell edge (feature) – down grades service request at cell edge – decrease coverage & improve capacity, but due to high little i values (RT > 1) especially for NRT 1 …2, we consider too much overshooting of adjacencies at cell level power. Summery:Summery: Small SHO areas (too late E1A activation) and high neighbor cell PwR overshooting (little i for NRT) decrease services, therefore total interference will increase and coverage will decrease but DYLO can not compensate all negative impacts of interference.
