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
