Performance measurement for mobile data streaming

Streaming via radio increased in mobile communications, with specific advantages for remote monitoring: distant and ubiquitous controlled and controlling parts. The authors used a real PLMN for mobile data acquisition and transmission. Virtual instrumentation was used for programming at the mobile or fixed probe and client side. At the probe it was used as a portable Digital Oscilloscope whose user-interface was emulated at the client like operating it on-site (non-perceptible delay, 3GPP real-time service [http://www.3gpp.org; (1)]. The goals were the identification of technical limitations, specific test methods and QoS assessment for mobile remote-measurement (by the delay parameter, related to round-trip time and jitter).
