Recent cross-layer MIMO systems have promised significant throughput
gains. Yet, these have been demonstrated on software radios as they
are considered incompatible with existing Wi-Fi radios and
protocols. OpenRF breaks this assumption; it is the first system to
show cross-layer MIMO on today's Wi-Fi devices and real
applications. OpenRF proposes new formulations of interference
alignment, nulling and beamforming designed for 802.11's MAC and
PHY. OpenRF has a software defined networking design for
self-configurability. OpenRF shows reduced delays and stalls for video
applications.
