Worldʼs First TV White Space Prototype Based on IEEE 802.22 forWireless Regional Area Network

January 30, 2013

The National Institute of Information and Communications Technology (NICT, President: Dr. Hideo Miyahara), Hitachi KokusaiElectric Inc. and ISB Corporation have developed the worldʼs first prototypes of base station (BS) and consumer premise equipment(CPE) based on the IEEE 802.22 standard operating in TV White Spaces (TVWS) (470 MHz - 710 MHz). The developed prototypes willprovide broadband wireless access to underserved and unserved regional areas around the world as well as bringing reliable backupbroadband communications in emergency, which will follow the worldwide trend of promoting the TVWS for wireless communicationsystems.

Background

From replacing the current analog television (TV) technology with digital television technology, some of the spectrum previously used byanalog television become vacant referred to as TV White Space (TVWS). The Federal Communications Commission (FCC) in the United States,the Office of Communications (Ofcom) in the UK, and the Ministry of Internal Affairs and Communications in Japan have initiated opening upthe TVWS to wireless communication systems for efficient reuse of the unused TV spectrum, which is based on non-interfering with broadcastincumbentsʼ operation. The IEEE 802.22 Working Group has published the IEEE 802.22-2011 standard for TVWS broadband wireless access toregional areas where it is most needed and where the TV spectrum is least used. In particular, the IEEE 802.22 systems offer around 10 timesthe coverage of Wi-Fi as well as enable to provide reliable backup broadband communications in emergency. However, there is no TVWSsystems based on the IEEE 802.22-2011 satisfying the FCC spectrum requirements.

Achievements

The NICT and Hitachi Kokusai Electric Inc. have developed the worldʼs first prototype devices of basestation (BS) and consumer premise equipment (CPE) verifying the physical (PHY) and the medium accesscontrol (MAC) layer design based on the IEEE 802.22 standard in the TVWS (470 MHz - 710 MHz). The PHYpart developed by Hitachi Kokusai Electric Inc. allows the devices to use vacant TV bands over the frequencyrange from 470-710MHz, the MAC layer part developed by NICT provides a medium access method based onpoint-to-multipoint access with supporting the different QoS levels, and supports cognitive capabilities ofinterference estimation, geo-location and white space data base (WSDB) access over the IP. The WSDB(http://whitespacetech.isbcorp.com/) provided by ISB Corporation avoids interference to incumbents of TVbroadcasters from automatically selecting the non-interfering TV band.

Future prospects

The NICT, Hitachi Kokusai Electric Inc. and ISB Corporation in the future will develop the enhanced technologies based on the IEEE 802.22standard and also work closely with WhiteSpace Alliance (WSA) (www.whitespacealliance.org) to provide products for worldwide markets. TheNICT, Hitachi Kokusai Electric Inc. and ISB Corporation will demonstrate the developed prototype devices at the Super WiFiSummit(www.superwifisummit.com) in Miami, Florida, from January 30 to February 1, 2013.
