About

Jihun Choi is a wireless communications researcher whose work centers on low-power, low-frequency radio systems designed to operate reliably in challenging, non-line-of-sight (NLOS) environments. His research addresses a critical gap in modern communications: enabling robust connectivity in complex indoor, urban, and infrastructure-poor settings where conventional higher-frequency systems struggle to penetrate obstacles and maintain reliable links. Choi's most influential contribution, "Low-Power Low-VHF Ad-Hoc Networking in Complex Environments" (2017, 27 citations), established a compelling case for leveraging the lower portion of the VHF band to achieve superior signal penetration for mobile agents in dense scenarios. Building on this foundation, his 2021 survey of small, low-frequency antennas (12 citations) has become a valuable reference for researchers tackling the practical design challenges inherent to compact antenna systems for IoT, robotics, and emergency response applications. Notably, his 2019 work demonstrated real-time digital video streaming over low-VHF links on robotic platforms, bridging theoretical networking concepts with tangible autonomous systems applications. Across his career, Choi has consistently advanced the case for low-VHF as a practical, scalable solution for next-generation wireless communications, influencing both hardware design and networking protocol development for resource-constrained, mobile platforms.
