This paper presents the results of a preliminary measurement campaign on beam adaptation for indoor moving users, comparing the path loss on a typical modern office floor and a lab floor. The performance of a static user beam is compared to that of an optimized user beam for the scenario of a user walking through a corridor. Results show that beam optimization is most beneficial when a line-of-sight is present. The gain of beam optimization decreases when the number of reflections required to establish a path increases. It is shown that the average path loss after beam optimization is lower on the office floor than on the lab floor that has a similar layout, but mainly metal instead of glass walls. The presented results show that glass walls on the office floor provide low-loss paths via reflections, while a glass window at the lab floor blocks paths.
