• Reduced development time—The CS8 has the industry’s most capable and easy-to-use development and debugging tools which can reduce product development time by weeks
• Optimized data service capabilities—Test with real payload data, not dummy packets ... even when you're testing high-speed throughput and IPv6
• Improved product quality—The CS8’s Protocol Tester functionality, including the IMS Message Flow Composer, enables fast development of design verification test cases that help identify bugs earlier in the R&D process
• Maximum Return on Investment—Cost-effective, scalable test platform minimizes long-term spending and brings value to every phase of the product life-cycle, from early-stage development to operator acceptance and deployment

A uniquely versatile, easy-to-use multi-cell, multi-RAT network emulator that addresses all phases of mobile device development.

A single CS8 instrument supports 2 LTE cells, all 3GPP LTE bands and bandwidths, plus integrated fading and MIMO (2x2 and 4x2).

The only network emulator to offer multiple automation interfaces that support all use cases:

• Interactive Tester: Interactive GUI for fast ad-hoc testing
• Protocol Tester: Rapid development of complex protocol test scenarios, e.g.,IMS/VoLTE
• Development Library UI: Easy test automation using a building-block approach
• Development Library SDK: Deep control of network emulation functions and events

Industry-verified real-time IPv6 Evolved Packet Core (EPC) provides multi-RAT network emulation with realistic connection anchoring points.

First to market with key 3GPP Release 10 features—the industry’s first network emulator to offer Carrier Aggregation with MIMO, fading, and noise in a single box.

The CS8 is at the heart of Spirent’s one-stop-shop leadership in IMS/VoLTE testing, including IMS protocol, VoLTE mobility, voice/audio quality, RCSe, E911 over VoLTE, and operator acceptance.

Scalable to support comprehensive location technology testing, including E911 over LTE, SUPL 2.0, LTE Positioning Protocol (LPP) and Observed Time Difference of Arrival (OTDOA).

• CS8 Wireless Device Design Tester Overview DatasheetSpirent’s CS8 Wireless Device Design Tester is the perfect testing platform for developers of LTE, UMTS, CDMA and multi-mode UEs and MS’s. A single hardware platform can be used in every stage of mobile device development.
• CS8 Protocol Tester DatasheetThe CS8 Protocol Tester is a suite of tools and utilities that help User Equipment (UE) and mobile device chipset developers address increasingly rapid evolutions of wireless technology. It expedites development and prevents low-layer bugs from ever making it out of the R&D lab.
• CS8 Wireless Device Design Tester for System Design and Platform Testing DatasheetCS8’s state-machine-based real-time protocol processing provides the world’s most advanced and realistic platform for system-level UE and chipset-platform testing.
• One-Stop-Shop for VoLTE TestingOffering a complete portfolio of testing capabilities from UE development to automated device acceptance, Spirent’s VoLTE testing solutions ease the challenges in designing and deploying mobiles devices that implement this complex and important technology.

• IMS Architecture: The LTE User Equipment PerspectiveThis paper provides an overview of IMS, its architecture and applications from the perspective of LTE User Equipment (UE. It also provides a look at the evolution to a data-only LTE network and includes a discussion of the challenges and requirements to support delivery of voice services (including VoLTE) over an all-IP network.
• IMS Procedures and Protocols: The LTE User Equipment PerspectiveThis reference guide provides an intuitive introduction to IMS procedures and protocols, focusing on those concepts most relevant to the UE designer.
• VoLTE Deployment and the Radio Access Network: The LTE User Equipment PerspectiveThe combination of IMS, SIP and RAN ultimately provides the “carrier-grade” VoLTE experience. This white paper identifies new and necessary RAN features and discusses how each improves the quality of VoLTE service.
