View Full Version : Effect on DL & UL power while doing IRAT
2011-01-07, 03:17 PM
What would be the effect on DL and UL power if IRAT (LTE-UMTS-EDGE) takes place? Lets suppose a user is in LTE coverage moves to an area with no LTE coverage but WCDMA(UMTS) and then to an area where theres no 3G coverage but only 2G coverage?

UL, ms/ue initiates an increase of mspower to conduct iRAT from 3G to 2G.. As the ms/ue moves and searches for 3g sites while in UTRAN network, power control technology from utran takes place so that it will enable to switch one technology to the other... u can verify this when will the iRAT ho takes place by viewing the Ec/Io and RSCP iRAT ho threshold. Before doing any SSV or cluster drive test, make sure that you have all the parameters of the sites including ho threshold and trigger. (i hope this one helps)
