Abstract: Using beamforming antennas to improve wireless multicast transmissions has received considerable attention recently.

In a switched beamforming system, the antenna typically provides a set of K single-lobe beam patterns of degree. 360/K covering the entire azimuth of 360o where ...

The work in proposes to partition all single-lobe beams into groups and to form composite multi-lobe beam patterns to transmit multicast traffic. The key ...

This work designs non-iterative, near-optimal beamforming algorithms based on the optimality conditions derived from its Lagrangian formulation that deliver ...

This paper revisits the key challenge-beam partitioning in the beamforming-multicast problem-and makes significant progress in both algorithmic and analytic ...

Abstract—We present the design and implementation of. ADAM, the first adaptive beamforming based multicast system and experimental framework for indoor ...

While the broadcast nature of the wireless medium intrinsically supports multicasting, link performance is dictated by that of the weakest client(s). With their ...

Briefly, smart antennas offer a variety of beamforming capabilities that can support transmissions at higher data rates, without degrading reliability. However, ...

Beamforming and its application in the form of multi-user MIMO in 802.11ac have the potential to change how networks are built and increase capacity.
