Test setup for anechoic room based MIMO OTA testing of LTE terminals

摘要: Over-The-Air (OTA) performance testing is becoming a key method for Multiple-Input-Multiple-Output (MIMO) enabled devices as it allows evaluation of most aspects the radio communication performance. This way has become very important research topic especially because MIMO now introduced into, example, LTE and WiMAX systems. The main purpose this to validate whether user equipment will have good in real use. CTIA, 3GPP COST are spending big effort standardizing OTA procedure which much more complex than similar single SISO testing. CTIA SubGorup (MOSG) comparing each proposed technique establish, first, an exact methodology second, ensure them offers comparable results. contribution focuses on multi-probe anechoic chamber solution summarizes activities related lab being built at Aalborg University (AAU), Denmark performed.
