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

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 …

Interference among co-channel users is a fundamental problem in wireless networks, which
prevents nearby links from operating concurrently. Directional antennas allow the radiation …

The use of directional antennas in wireless networks has received growing attention
because of its high spatial reuse and high antenna gains. The Medium Access Control …

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 …

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

Using directional antennas can be beneficial for wireless ad hoc networks consisting of a
collection of wireless hosts. To best utilize directional antennas, a suitable medium access …

Previous research in wireless ad hoc networks typically assumes the use of omnidirectional
antennas at all nodes. With omnidirectional antennas, while two nodes are communicating …

Capacity of wireless mesh networks can be enhanced through the use of smart directional
antennas, which not only enable nodes to have high quality links but also increase network …

We investigate the possibility of using directional antennas for medium access control in
wireless ad hoc networks. Previous research in ad hoc networks typically assumes the use …
