Topic: Ultrawideband: The "Ultra" White Space Technology
Speaker: Jim Landsford, CTO, Alereon
Abstract:
With all the debate over use of spectral "white spaces"
in the UHF bands, there is a technology that is already having to use
cognitive and white space processing in an attempt to achieve efficient
spectral reuse and extraordinary speeds: ultrawideband. These "Detect
and Avoid" techniques are primarily targeting coexistence with systems
in the 3-5GHz band (C-Band) that UWB must coexist with globally. The
bands above 6GHz (X-band) are largely free of restrictions, where UWB
can operate as a pure spectral underlay. This talk will highlight the
status of UWB and the detection and mitigation techniques that are
being developed today to create the huge wireless USB, high speed
Bluetooth, and UWB over coax markets.
Speaker:
Jim Lansford is the Chief Technology Officer of
Alereon, one of the pioneers in UWB technology. In addition to
developing advanced technologies and architectures for future UWB
systems, he is heavily involved in a number of standards, trade groups
and regulatory activities. Dr. Lansford was formerly co-chair of IEEE
802.15.3a High Rate WPAN Task Group, chair of the IEEE 802.19 Wireless
Coexistence Technical Advisory Group and vice chair of the 802.15.2
Coexistence Task Group. He received his BSEE from Auburn, his MSEE
from Georgia Tech, and his Ph.D. EE from Oklahoma State.
