Tester with mobile devices

Third-party apps on smartphones and tablets are sometimes backed by faulty or poorly designed software that can produce excessive IP data traffic and drain a device’s battery, even when the app isn’t active. In the past, manufacturers or network operators didn’t have the ability to analyze mobile apps to detect which ones were negatively affecting a device’s performance. This application note discusses how a wideband communications tester combined with a data application unit with a traffic analysis option can be used to perform application based end-to-end tests at the IP level, including data traffic and protocol analysis.
