Recently, rapid increase of mobile devices pushed the radio frequency (RF)-based wireless
technologies to their limits. Free-space-optical (FSO), aka optical wireless, communication …

Compared with omni‐directional antennas, directional antennas have many merits, such as
lower interference, better spatial reuse, longer transmission range, and improved network …

The 60 GHz wireless technology that is now emerging has the potential to provide dense
and extremely fast connectivity at low cost. In this paper, we explore its use to relieve …

60 GHz technology holds tremendous potential to upgrade wireless link throughput to Gbps
level. To overcome inherent vulnerability to attenuation, 60 GHz radios communicate by …

Due to high directionality and small wavelengths, 60 GHz links are highly vulnerable to
human blockage. To overcome blockage, 60 GHz radios can use a phased-array antenna to …

Mobile devices cannot rely on a single managed network, but must exploit a wide variety of
connectivity options as they travel. We argue that such systems must consider the derivative …

Visible Light Communication (VLC) is a fast-growing technology to provide data
communication using low-cost and omni-present LEDs and photodiodes. In this paper, we …

Multi-User MIMO promises to increase the spectral efficiency of next generation wireless
systems and is currently being incorporated in future industry standards. Although a …

With the proliferation of WiFi technology, many WiFi networks are accessible from vehicles
on the road making vehicular WiFi access realistic. However, several challenges exist: long …

Low robustness under mobility is the Achilles' heel of the emerging 60 GHz networking
technology. Instead of using omni-directional antennas as in existing Wi-Fi/cellular networks …
