  • About the Laboratory & Research Area
  • ▶ 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.
