▶ About the Laboratory
We conduct research on wireless networking, well-balanced between theory and practice
by (1) developing new networking protocols/algorithms and (2) evaluating/demonstrating
them via analysis, simulation, and system building.
▶ Research Area
Our research interests include the protocols/algorithms/applications for wireless networking!
At this time, we are in particular working on WiFi, LTE, and their future evolutions including
femtocell, CoMP, VoLTE, VoWiFi, and MIMO.
