We report a first-of-its-kind realization of directional transmission for smartphone-like mobile
devices using multiple passive directional antennas, supported by only one RF chain. The …

Directional antenna technologies have made significant advancements in the last decade.
These advances have opened the door to many exciting new design opportunities for …

The demand for wireless bandwidth in indoor environments such as homes and offices
continues to increase rapidly. Although wireless technologies such as MIMO can reach link …

In this work, we report the first study of an important realization of directional communication,
beamforming, on mobile devices. We first demonstrate that beamforming is already feasible …

Recent work demonstrates that directional antennas have significant potential to improve
wireless network capacity in indoor environments. This paper provides a broader …

In this paper, we design and implement a long-range and broadband aerial communication
system using directional antennas (ACDA). The system integrates Wi-Fi devices with aerial …

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

SPAWAR Systems Center Pacific has spent several years developing directional wireless
networks. These networks harness the power of highly directive antennas (range extension …

Increasingly, directional antennas are being used in wireless networks. Such antennas can
improve the quality of individual links and decrease overall interference. However, the …

The capacity of wireless ad hoc networks is affected by two key factors: the interference
among concurrent transmissions and the number of simultaneous transmissions on a single …
