Rohde & Schwarz GmbH & Co. KG, or R&S, a provider of electronic test and measurement equipment, has unveiled an integrated test solution with IP and protocol statistic analysis for detailed assessment of data transmission on smartphones.
Equipped with the new R&S CMW-KM051 option, the R&S CMW500 wideband radio communication tester can analyze and test IP-based applications using ipoque's deep packet inspection (DPI) engine.
The combination of RF and application testing in a single instrument allows network operators and smartphone manufacturers to test how mobile apps affect the performance of wireless communications and mobile phone networks, the company said.
The R&S CMW500 provides a testing environment for wireless communications networks such as LTE, WCDMA and even WLAN. Using the integrated data application unit, the instrument combines standard RF testing requirements with the IP world.
By adding the R&S CMW KM051 option, the R&S CMW500 can analyze and test IP-based applications, giving network operators a way to qualify applications or optimize them for their networks. Smartphone manufacturers can also obtain more precise information on how certain applications affect resources such as battery capacity.
The IP analysis involves logging each IP data packet that is sent and received at the IP protocol level. The following functions are available for more precise analysis: list of active IP connections, TCP analysis, list of protocols used, data volume statistics, protocol name resolution, and triggering on IP events. The intelligent and reliable IP analysis records the IP traffic of applications even when they are active in the background. This makes it possible to identify error sources, the company added.
