This paper presents a low-cost measurement method for MIMO antenna performance assessment based on the open-source OpenAirInterface initiative. A first measurement is presented with a prototype with 8 antennas at 2,6 GHZ integrated into a 140x140x40 mm fento cell and using Laser Direct Structuring (LDS) technique. The setup is validated through a beamforming gain measurement in a MISO 4x1 configuration in LTE TDD mode. We achieved the expected 6 dB beamforming gain between a SISO and 4×1 MISO configuration.
