QualityAssurer Series—QA-604/QA-805/QA-813


QualityAssurer Series—QA-604/QA-805/QA-813

Industry’s Most Powerful and Flexible Platforms

EXFO’s latest QualityAssurer series of platforms is targeted at NEMs and NSPs that are developing and deploying IMS and wireless networks. The QualityAssurer offers easy-to-use test solutions covering the complete testing lifecycle of LTE, IMS, VoLTE and VoIP networks and services.

With the QualityAssurer, EXFO has leveraged its leadership in IMS and wireless (2G/3G/LTE) testing to deliver unmatched signaling and user-plane testing capability in an integrated platform.

Real-World Network Testing

Combined with the W2CM-10GbE module, the QualityAssurer can emulate tens of millions of subscribers generating traffic to emulate any real-world network condition, enabling NSPs and NEMs to test different scenarios in their labs. It can also emulate various network elements within the LTE, IMS or VoIP networks to perform wrap-around testing of network elements, thereby ensuring that the network being developed or deployed exceeds customer expectations.

End-to-end testing of 4G networks requires the ability to generate and analyze voice, video and data sessions from subscribers through the LTE and IMS networks. The QualityAssurer can generate voice (VoLTE) and video calls, data sessions (such as HTTP web browsing, SMTP e-mail downloads, FTP file downloads and messaging), simultaneously, across millions of users with traffic distributions that are representative of real-world networks. These sessions are generated and analyzed in real time, and at line rate, providing key measurements of quality of service (QoS) parameters such as mean opinion score (MOS), delay, jitter and packet loss. The statistics across these sessions can be grouped by user-defined values (e.g., QoS class identifier (QCI) and CODECs), so as to facilitate easy identification and resolution of network issues.

4G/LTE Testing

LTE RAN Testing

The eNodeB includes all radio-related functions, and the LTE radio interface is up to 10 times faster than the interface in WCDMA.

Radio-related measurement reports coming from UEs are not visible outside the radio interface, which can make radio interface optimization challenging. QoS verification for VoLTE services, data applications and video broadcasting increase the need for sophisticated testing tools.
