LSTI Friendly Customer Trials (FCT)Consolidated Test Methods For LTE

Common Recommendations for Trial Network Set-Ups

Common Definition of Key Performance Indicators (KPIs) Common Generic Procedures for Trial Configuration 42 test s ecifications rou ed in 13 testin domains

Methodologies Consistent with NGMN Field Trial Rqmts LSTI FCT split in 2 Trial Phases:

- Phase I- Radio Access testing with Non-Commercial/Simulated EPC

- Phase II- Testing with EPC & E2E Using Commercial Network

Cell Capacity

NGMN essential ranges for Spectrum Efficiency: 1.59 - 2.65(DL),0.99 - 1.65(UL) are met.

For a 20MHz bandwidth, the normalized average Cell Capacity isapproximately 40 Mbps

PlansMore Radio and E2E PerformanceTesting

Continue Testing- Radio Access Testing and E2E TestingPhases are Planned Through 2010

Analyze Results- On a Test Domain Basis, LSTI FCT

Group will Analyse Results
