無線ワイヤレススマートユーティリティネットワーク(Wi-SUN)は,通信機能を搭載する電気/ガス/水道等の各種スマートメータの情報収集,遠隔制御への応用のほか,構造物モニタリング、農業、医療等の各種アプリケーションにも活用できる.しかし,Wi-SUN ネットワークにおいて,膨大な数のメータ・センサーが存在す
るため,輻輳や干渉などの原因でWi-SUN 無線システムの性能が劣化する.そこで,柔軟かつ高度に周波数を活用するためのTV ホワイトスペース(TVWS)技術を用いるTVWS-Wi-SUN システムの開発が期待されており,標準化,実用化が急務となる.2014 年,TVWS-Wi-SUN に関連する国際標準規格IEEE 802.15.4m がリリースされた.NICT(独立行政法人 情報通信研究機構)では,IEEE802.15.4m に準処した無線機の開発を行った.本稿では、開発した無線機の特性を検証するための室内実証実験を実施し,評価した結果について報告する. |

This article presents the development and the laboratory experiment of radio equipment for TV White Space wireless smart utility network (TVWS-Wi-SUN). A Wi-SUN is a ubiquitous wireless network that monitors, commands, and controls for service providers at one end, and measures, collects, and analyzes data for consumers at the other. Utility control
and metering are typical Wi-SUN usage. In addition, agriculture monitoring, street light, and industrial automation system are
also the target usage of Wi-SUN. It is notable that Wi-SUN can support many kinds of application. However, congestion and interference issues degrade the network system efficiency since several thousands of meters or sensors potentially exit in the network. Additionally, how to cover the wide service area is another issue for Wi-SUN. To address these issues, the TV white space communication technology, which occupies the requencies allocated to TV broadcasting services but not used locally, receives overwhelming attention. Despite the fact that Wi-SUN and TVWS are independent and uncorrelated technologies, they can be combined to create a hybrid ecofriendly wireless network system, named TVWS-Wi-SUN. For promoting the TVWS-Wi-SUN system, the IEEE802.15.4m, which is the standard for the TVWS wireless personal area networks (WPANs), has been released. The NB-OFDM based solution for TVWS-Wi-SUN is proposed in IEEE 802.15.4m. For implementing TVWS-Wi-SUN, the radio equipment based on IEEE 802.15.4m is developed. In this article, the performance of the developed radio equipment is verified through laboratory experiment. Experimental results provide a solid foundation to the developed radio equipment in achieving the requirements of TVWS-Wi-SUN system. |
