MWC 2015: Rohde & Schwarz adds test option for analyzing mobile app behaviour

Rohde & Schwarz has presented its over the top (OTT) application analysis solution for the first time ever at Mobile World Congress. This solution enables network operators and mobile device manufacturers to quickly and easily analyze and assess the behavior of OTT apps on mobile devices. 

It is an additional software option 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 tried and tested PACE software from Rohde & 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. Analysis results are available in a clearly structured graphical report. Users will appreciate features such as the clear overview of an app's data throughput over time, its connected and idle state information and when RRC messages were initiated.

The test setup for OTT application behavior is on display at Mobile World Congress in Barcelona (hall 6, booth C40). 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.
