dc.description.abstract | Recent studies show that high-power cross-technology interference
is becoming a major problem in today’s 802.11 networks. Devices
like baby monitors and cordless phones can cause a wireless
LAN to lose connectivity. The existing approach for dealing
with such high-power interferers makes the 802.11 network switch
to a different channel; yet the ISM band is becoming increasingly
crowded with diverse technologies, and hence many 802.11 access
points may not find an interference-free channel.
This paper presents TIMO, a MIMO design that enables 802.11n
to communicate in the presence of high-power cross-technology
interference. Unlike existing MIMO designs, however, which require
all concurrent transmissions to belong to the same technology,
TIMO can exploit MIMO capabilities to decode in the presence
of a signal from a different technology, hence enabling diverse
technologies to share the same frequency band. We implement a
prototype of TIMO in GNURadio-USRP2 and show that it enables
802.11n to communicate in the presence of interference from baby
monitors, cordless phones, and microwave ovens, transforming scenarios
with a complete loss of connectivity to operational networks. | en_US |
