Tomohiro Arakawa, Ph.D.
Software Defined Radio Engineer at Lynk
Many devices including laptops, smartphones, and tablets are connected to WiFi or Bluetooth so you can use them virtually anywhere. However, we are still charging these devices with copper cables. We are studying a way to efficiently transfer energy to the remote devices without wires by applying the theory of digital communications.
If we can transfer energy to remote devices, then we can send information as well. However, the optimal strategy for the power transfer is different from the one for the information transfer. In this research, I am mainly investigating the tradeoff between the data rate and transferred power.
Spectrum scarcity is becoming a significant problem for wireless communication systems. DARPA Spectrum Collaboration Challenge (SC2) aims to solve the issue by utilizing software defined radio (SDR), machine learning, and collaboration. I am participating in SC2 as a member of our team (Team BAM! Wireless), and mainly designing the physical layer of the radios. We were ranked in the top 10 teams at the Preliminary Event 1, which was held in December 2017.
