Hi Peter, We tested both the Beam+ and a unit from Double Robotics using 802.11r and 5 GHz in a four AP lab environment. We found that the iPad the Double uses has slightly better roaming behavior, especially with 802.11r enabled. It was still occasionally inconsistent, though, and the Double product does not give detailed connection statistics like Beam+ UI does so it was harder to measure our qualitative observations.
