Topic:  Ultrawideband: The "Ultra" White Space Technology
Speaker:  Jim Landsford, CTO, Alereon

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.
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.
