This paper describes an outdoor MIMO measurement campaign conducted in the 2GHz band employing a sounding bandwidth of 20MHz. The study aimed to compare the MIMO performance of two prototype devices with a reference dipole antenna module. The results obtained reveal a systematic blocking of one of the PDA antenna ports with the user’s thumb alongside a significant reduction in the available MIMO channel capacity. The laptop MIMO enabled device was found to offer good MIMO capacity enhancement, matching the performance achieved with the dipole antennas.
