The multi-Gbps throughput potential of 60 GHz wireless interfaces make them an attractive technology for next-generation gigabit WLANs. For increased coverage, and improved resilience to human-body blockage, beamsteering with high-gain directional antennas is emerging to be an integral part of 60 GHz radios. However, the real-world performance of these state-of-the-art radios in typical indoor environments has not previously been explored well in open literature.

To this end, in this paper, we address the following open questions: how do these radios perform in indoor line-of-sight(LOS) and non-line-of-sight (NLOS) locations? how sensitive is performance to factors such as node orientation or placement? how robust is performance to human-body blockage and mobility? Our measurement results from a real office setting, using a first-of-its-kind experimental platform (called Presto), show that, contrary to conventional perception, state-of-the-art 60 GHz radios perform well even in NLOS locations, in the presence of human-body blockage and LOS mobility. While their performance is affected by node (or more precisely, antenna array) orientation, simply using a few more antenna arrays and dynamically selecting amongst them shows potential to address this issue. The implications of these observations is in lowering the barriers to their adoption in next-generation gigabit WLANs.
