JDSU (NASDAQ: JDSU; and TSX: JDU) innovates and markets diverse technologies that enhance the way people experience the world every day. We enable fast, high-quality communications, secure financial transactions, reliable consumer electronics, green energy, differentiated brands and a host of other solutions. We provide these solutions through three business segments: Communications Test and Measurement, Communications and Commercial Optical Products, and Advanced Optical Technologies.

The Vancouver based Wireless Capacity Solutions Business produces the industry's most advanced and scalable wireless subscriber simulation and test systems for CDMA, UMTS, HSPA and LTE technologies.

The system supports:

• Functional Feature Tests to verify RF performance of LTE and UMTS subsystems
• System Performance Tests with mixed data applications measuring max data throughput, packet latency, jitter, etc. under dynamic RF environments.
• Call Model Tests to verify system performance under real-world traffic scenarios.
• Stress Testing under Traffic Load measuring impact on RF resources, Scheduler performance, CPU and RAM capacities as well as integrity of signaling under load.
• Data Application Performance Tests measuring Quality of Service and its impact on data throughput for mixed data traffic.

JDSU's DMTS systems use patented software defined radio (SDR) techniques to generate realistic traffic patterns, subscriber call model behavior and emerging data applications in order to test the capacity, performance and reliability of 3G and 4G networks.

Modern 3G and 4G Mobile networks are both dynamic and adaptive in nature with network intelligence moving out of the core and into the edge of the access networks. The test challenge now is to simulate subscriber behavior at both the RF and IP interfaces to ensure quality and performance objectives have been met. That challenge has been successfully met by Dyaptive Systems with systems deployed by virtually all leading Radio Access Network (RAN) manufactures and many of the worlds leading mobile network operators.
