R&S CMW-PQA Test System for Performance Quality Analysis, by Rohde & Schwarz.

Rohde & Schwarz is presenting its new over-the-top (OTT) application analysis solution at Mobile World Congress, being held this week in Barcelona, Spain. The solution enables network operators and mobile device manufacturers to quickly and easily analyze and assess the behavior of OTT apps on mobile devices the data traffic they cause.

The additional software option is for the established R&S CMW-PQA performance quality analysis test system.

OTT apps are applications such as YouTube and WhatsApp that use mobile networks, but are not a service offered by the network operator. Such apps can cause uncontrolled data traffic on an operator’s network and excessively drain mobile phone batteries.

The R&S CMW-PQA OTT software now allows users to check which server the OTT app registers with, the number of connections it initiates and the network traffic volume it generates. The R&S CMW500 wideband radio communication tester, the core component of the R&S CMW-PQA, also offers a unique IP and protocol statistical analysis function that enables users to analyze how much the OTT app drains the mobile phone battery. The PACE software fromRohde & Schwarz subsidiary ipoque integrates this precise application identification function into the device.

The intuitive user interface enables users to quickly and easily configure tests as usual, Rohde & Schwarz said. Analysis results are available in a clearly structured graphical report. Users will have a clear overview of an app’s data throughput over time, its connected and idle state information, and when RRC messages were initiated.

The OTT solution for the R&S CMW-PQA test system is now available from Rohde & Schwarz. Customers who already have an R&S CMW-PQA do not need to purchase a hardware upgrade. A software upgrade is all that is required to add the OTT functionality to their system.

The test setup for OTT application behavior is on display at Hall 6, Booth C40, at Mobile World Congress.
