Overview

• TM500 is used by every Tier 1 Network Equipment Vendor for 3GPP base station development

– ‘De facto Standard’ within the industry for WCDMA, LTE & LTE-Advanced testing

• TM500 & E500 used as load & interoperability reference tool provides key benefits

– Dramatically reduces time from weeks to days needed to get started ‘out of the box’ as we have already integrated with all Tier 1 vendors

– Debug your network/infrastructure, not your test tool

– 1 UE / Single UE advanced features already proven before migration to load test system

• TM500 & E500 used for end to end LTE system testing for over 5 yrs

– We have a long record of debugging network/infrastructure equipment

– We know how to test both 3GPP functionality and capacity

• Custom-designed AF/Shenick solution

– Adapted for use in wireless environment

– D500/D1000 is exclusive to TM500/E500

• Fully stateful data service synchronised PER UE

– Full interaction of Application & IP transport protocols with radio environment

as in the real world; NO simulation

– Provides application measurements ideal for end to end testing

• e.g. latency, jitter

– Supports user Quality of Experience measurements

• e.g. MOS voice quality

– Fully integrated with GUI, one point of control
