IEEE 802.22 Standard: Regional and Rural Area Broadband Wireless Access Using Cognitive Radio Technology in Television Whitespaces

Apurva N. Mody, Chair, IEEE 802.22 Standard Working Group

apurva This talk will be about the IEEE 802.22 Standard on Wireless Regional Area Networks (WRANs) which was published in July 2011. 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 rural communities, which are estimated to include nearly half of the worlds population. The IEEE 802.22-2011 is the first IEEE 802 Standard for operation in the Television (TV) Whitespaces, defined as the available or un-occupied TV channels. It is also the first IEEE Standard that focuses on broadband connectivity in rural areas where most vacant TV channels can be found, thus helping to bridge the digital divide. IEEE 802.22 Working Group is the recipient of the IEEE SA Emerging Technology Award. 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 could deliver 22 Mbps to 29 Mbps, depending upon the country of deployment, without interfering with reception of existing TV broadcast stations. IEEE 802.22 incorporates advanced cognitive radio capabilities including dynamic spectrum access, incumbent database access, accurate geo-location techniques, spectrum sensing, regulatory domain dependent policies, spectrum etiquette, and -coexistence for optimal use of the available spectrum. The members of the IEEE 802.22 Working Group have established the Whitespace Regional Area Networks Alliance (

Dr. Apurva N. Mody ( is the Chair of IEEE 802.22 Working Group (WG) for Wireless Regional Area Networks (WRANs) ( He is the driving force behind the WhiteSpace Regional Area Networks Alliance ( The primary aim of the IEEE 802.22 WG is to create commercial wireless standards that will use TV Whitespaces to enable rural broadband wireless access. Under his leadership, the IEEE 802.22 WG is the recipient of the IEEE SA 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 BAE Systems Technology Solutions. Dr. Mody has played a pivotal role in growing the BAE Systems expertise and market share on Cognitive Radio (CR), Dynamic Spectrum Access (DSA) related systems. He has been a key contributor on many DoD programs and invited speaker at many DoD and commercial events. Dr. Mody is a Senior Member of the IEEE, President' s Fellow while at Georgia Tech, Member of Tau Beta Pi and Eta Kappa Nu Honor Societies.

The meeting begins at 7 p.m. at the new meeting auditorium at the Verizon Technology Center. The address is 60 Sylvan Road, Waltham, MA 02451. The entrance is by the far corner, with the picnic tables out front, and not the tower or the new building. It is most easily reached by the West Street entrance. Verizon prefers that we provide a list of attendees in advance, so if you want to come, you need to register at, but admission is free.

We will be taking Apurva to dinner at the Green Papaya before the talk at about 5:30 pm.
