With a total of 3 patents, his work has advanced the capabilities of wireless communication technologies.
Latest Patents
Yoon Seok Nam's latest patents focus on innovative methods for estimating the position of mobile nodes in wireless sensor networks. One of his notable inventions is a method that estimates a frequency offset between anchor nodes and calculates the time difference when ranging frames from a mobile node are received by two anchor nodes. This method does not require a separate synchronization unit, which is a departure from conventional methods that rely on Time of Flight (TOF) using Two-Way Ranging (TWR) and Symmetric Double Sided-TWR (SDS-TWR) schemes. The estimated receiving time difference is directly applied to a Time Difference Of Arrival (TDOA) algorithm to accurately estimate the position of the mobile node. Another patent involves a passive mode OWR method for estimating the position of a mobile node, allowing multiple mobile nodes to determine their positions with minimal ranging frame transmissions.
Career Highlights
Yoon Seok Nam has worked with esteemed organizations such as the Electronics and Telecommunications Research Institute and the Korea Telecommunication Authority. His experience in these institutions has contributed to his expertise in wireless communication technologies and sensor networks.
