Title: IEEE 802.22 Standard for Wireless Regional Area Networks - Enabling Rural Broadband Wireless Access Using Cognitive Radio Technology

Dr. Apurva N. Mody
Chair of the IEEE 802.22 Working Group on Wireless Regional Area Networks

Horário: 31/08 - Quarta-Feira

Abstract: The IEEE 802.22 Working Group on Wireless Regional Area Networks
has developed the first IEEE Standard for Television Whitespaces using state
of the art Cognitive Radio (CR) features that has been specially developed
for rural broadband access. The IEEE
802.22 Working Group is the recepient of the 2011 IEEE SA Emerging
Technology of the Year Award. IEEE 802.22 systems will provide broadband
access to wide regional areas around the world and bring reliable and secure
high-speed communications to under-served and un-served communities. This
new standard for Wireless Regional Area Networks (WRANs) takes advantage of
the favorable transmission characteristics of the VHF and UHF TV bands to
provide broadband wireless access over a large area up to 100 km from the
transmitter.
Each WRAN will deliver up to 22 Mbps per channel without interfering with
reception of existing TV broadcast stations, using the so-called white
spaces between the occupied TV channels. This technology is especially
useful for serving less densely populated areas, such as rural areas, and
developing countries where most vacant TV channels can be found. IEEE 802.22
incorporates advanced cognitive radio capabilities including dynamic
spectrum access, incumbent database access, accurate geolocation techniques,
spectrum sensing, regulatory domain dependent policies, spectrum etiquette,
and coexistence for optimal use of the available spectrum.

About the speaker: Dr. Apurva N. Mody (apurva.mody@ieee.org) is currently
the Chair of IEEE 802.22 Standard on Cognitive Radio based broadband
wireless access in the VHF / UHF spectrum allocated to the TV band devices
(www.ieee802.org/22). Under his leadership, the IEEE
802.22 Working Group has received the IEEE SA 2011 Emerging Technology of
the Year Award. Dr. Mody received his Ph. D. in Electrical Engineering from
Georgia Institute of Technology in December 2004. His research was based on
Receiver Implementation for Multiple Input Multiple Output Orthogonal
Frequency Division Multiplexing Systems.
Since June 2005, he has been working at the BAE Systems Technology Solutions
on various projects involving Cognitive Radio (CR), Dynamic Spectrum Access
(DSA) and Cognitive Networks (CN). Dr. Mody has made contributions to the
advancement of technologies such as spectrum sensing, signal detection,
parameter estimation, feature extraction, signal classification, machine
learning, game theoretical formulations, signal space and policy based
management, fusion algorithms etc. Dr. Mody was awarded President’s
Fellowship at Georgia Tech and he is a member of Eta Kappa Nu and Tau Beta
Pi. His research work has been published in two book chapters, numerous
publications and patents.
