We have regular research seminars every Tudesday and Thursday. The topics vary from different areas within the field of wireless data broadcast, including optimization strategies, system architectures, indexing technologies, and emerging data broadcast problems of the next generation wireless networks.

The schedule of our seminars is as follows:

Time 2:00pm~4:00pm, Tuesday & Thursday
Location ECSS 4.910

You are welcome to join us during our seminars.
