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

First Results Meet Expected Performance Levels
Throughputs Measured peak rates for FDD & TDD normalized to
20 MHz meet or exceed NGMN Field Trial expectations ofat least 100 Mbps for DL and 30-50 Mbps for UL

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
Disclosure- Performance levels and related testconditions will be displayed
