Outline of Final Research Achievements

This research aims to develop an accurate indoor localization technology for narrow-band, low-power wireless communication technologies such as BLE (Bluetooth Low Energy) and ZigBee (IEEE 802.15.4). Low-power narrow-band wireless communication technologies such as BLE and ZigBee tend to suffer from a low localization problem due to multiple wireless signal paths. We therefore developed an accurate indoor localization technology relying on differences in multiple channels. Wireless communication in different channels has different responses depending on location and channel. We utilize the difference to improve localization accuracy.

Academic Significance and Societal Importance of the Research Achievements

本研究により，ZigBeeやBLEを用いた測位において推定精度の著しい低下を防ぐ技術が確立されたと言える．これまで測位精度の問題でWi-Fiを採用せざるを得なかったようなIoT機器における通信モジュールの置き換えに大きく寄与できる．通信モジュールの置き換えは通信性能の低下につながるが，消費電力の低下に伴ってより小型なデバイスの実現も可能となるなど，副次的な面も含めると大きな波及効果が期待できる．また，広帯域化する無線通信方式にも応用ができる方式であることから，より通信とともに高精度な測位を実現するための基盤技術になりうると期待される．
