Within the research project ZIM IRAP, QUALIGON implements a testbed at the laboratory of the Technical University Chemnitz. The testbed is intended to support the development of a new approach for LTE small cells from the quality perspective. These LTE small cells will be deployed in closed areas and provide mobile internet connectivity e.g. at industrial sites or office environements. The testbed embeds mobile devices in combination with SIM switching technologies by QUALIGON. In this setup, the Appium framework is used to control over-the-top (OTT) apps on the mobiles for traffic generation and quality assessments, while the SIM switching allows to change SIM profiles between tests. This combination provides a high flexibility and variability of the considered test scenarios. The whole setup is remotely.
