Today’s device delivers voice, navigation, data services and more, sometimes simultaneously.

Mobile devices and chipsets are more complex than ever. The device must now accommodate multi-antenna techniques (MIMO) while roaming between networks of multiple radio access technologies using different frequency bands. Today’s device delivers voice, navigation, data services and more, sometimes simultaneously. The interplay between protocol layers mean that designers can no longer catch and “patch-fix” fundamental bugs during field-testing.

What to Test

Due to the interdependencies between multiple elements at multiple protocol layers, today’s device designer must be able to quickly and completely control a simultaneous integrated emulation of multiple network and radio access elements. Cellular devices and chipsets must be evaluated for:

• Operation with the IMS subsystem (especially Voice over LTE, or VoLTE operation)
• Increasingly complex Evolved Packet Core (EPC)
• MIMO antenna techniques
• Roaming between radio access networks (using multiple radio technologies)

When issues arise, the designer must be able to quickly isolate causes, make fixes, and conduct regression tests, even if the design is nowhere near complete.

Spirent Solutions

Today, time-to-market calendars are short and design teams are lean. Spirent is committed to helping wireless engineers deliver better-quality products in less time.

• CS8 Device Tester offers a unique set of tools that help designers deliver flawless designs quickly. At the engineer’s fingertips are a real-time Evolved Packet Core (EPC), IMS subsystem and, multiple cells using multiple simultaneous Radio Access technologies (RATs).
• CS8 Protocol Tester includes a suite of purpose-specific tools so the engineer can quickly create any imaginable scenario for testing. CS8 protocol control is complete yet efficiently intuitive. The result is a design that has been battle-tested before it leaves the R&D lab.
