Test method for narrowband F/TDMA-based wireless sensor/actuator networks including radio channel emulation in severe multipath environments

Cammin, Christoph; Krush, Dmytro; Heynicke, Ralf; Scholl, Gerd

A test method for narrowband wireless sensor/actuator networks is presented, facilitating affordable and efficient performance and compliance tests prior to the deployment of the wireless communication systems. Commonly used channel models are examined to derive a worst-case test scenario. Employing frequency/time division multiple access (F/TDMA) techniques and protocol synchronization, a new and efficient test method is suggested, where the equipment under test (EUT) is evaluated under the worst-case scenario. A cost-efficient channel emulator is introduced to emulate fading in multipath environments. Also, industrial interferes can be included in the setup. Furthermore, a procedure to test wireless devices with integrated, non-detachable antennas is presented.
