The latest generation of this Quality of Service (QoS) wireless benchmarking system, allows cellular operators to evaluate competitive network performance from the subscriber’s perspective while simultaneously gathering engineering performance data on their own networks.

Flexible and scalable
Any combination of test phones, data cards, and scanning receivers can be configured – up to a total of 24 devices. All major air interface technologies are supported, including GSM/EDGE, UMTS, HSPA, CDMA-1x, EvDO Rev A, and iDEN, making Multi an ideal platform for the evaluation and measurement of multiple diverse wireless systems.

Mix-and-match of technologies
Harnessing the efficiency of multiple parallel test phones/cards with the in-depth analysis capabilities of the scanning receiver, Symphony Multi provides the most capable, full-featured mobile test system in the industry.  Each Single Board Computer (SBC) module can support one test phone and one data card interface, increasing the number and type of simultaneous tests that can be performed and reducing the amount of hardware required.

Proven history
Built on the widely deployed Multi hardware system from Ascom Inc. (formerly Comarco), Symphony is also available as an in-line upgrade for their extensive existing installed base of QoS measurement products.

All-in-one scanning receiver
Symphony Multi employs the latest generation 3G scanning receiver – a flexible, precise, and powerful resource for advanced network problem diagnosis.  Tightly coupled to calling module operation, the scanner provides an independent and powerful diagnostic tool, facilitating real-time interference and problem analysis.

Worldwide Support
Built to exacting standards and backed by superior worldwide support, the Multi is designed to operate reliably in real world field conditions under harsh operating environments, ensuring integrity of data collection and maximizing engineering productivity.
