With the launch of LTE services by multiple service providers across the world, telecom equipment manufacturers (TEMs) must deliver innovative, differentiated, and cost-competitive products in order to succeed in the wireless ecosystem of the future.

We provide a comprehensive set of testing services to help TEMs deliver differentiated solutions across the entire LTE ecosystem. Backed by a team of more than 1,800 dedicated test engineers, our testing services are based on a strong foundation of domain expertise across access, core, and wireless LTE networks.

TEST PLANS AND SUITES

We have a rich repository of reusable/customizable test cases and in-house stubs to test for various LTE network elements, including:

TEST SIMULATORS AND FRAMEWORKS

Our in-house test simulators and automation frameworks help TEMs deliver superior product quality and accelerate time to market for LTE products.

> Software Tool for Automated Test Environment (STATE): STATE accelerates unit testing, subsystem and system integration testing, and regression testing of 2G/2.5G/3G/LTE products. This platform agnostic tool allows script creation and execution, event tracking, logging, and customizable statistics and reports.

> LTE Network Element Simulators: Our LTE network element simulators are 3GPP R8-compliant. They include:

• Aricent LTE PGW Lite

• Aricent LTE SGW Lite

• Aricent LTE EPC Lite

• Aricent LTE MME

• Load generator (UE + eNodeB, for load and performance testing)

• Aricent LTE HSS

• Aricent LTE EPC NMS

• STATE and MME libraries

TEST EQUIPMENT

Our investments in test equipment and infrastructure are vital to our delivering testing expertise across the entire LTE ecosystem. Our test equipment includes traffic generators and analyzers from leading vendors such as SignaLion, IXIA, Spirent, Agilent, etc. Additionally, our labs are equipped with routers and switches from Cisco, Juniper, and HP.
