Advances in Beyond 3G Wireless Communications and Networks

September 25-29, 2006

Santorini Island, Greece


Advances in wireless communications and networks are leading to novel architectures and paradigms as complex wireless devices with sophisticated modalities are integrated into the communication infrastructure. This summer school provides a systematic overview of wireless communications with a view towards beyond 3G architectures and paradigms. The topics of the summer school span advances in physical layer for wireless communications, MIMO systems as well as advances in wireless networks going from the access up to the transport layer. The summer school is organized into short courses taught by experts in the academic community. The curricula of these courses are interconnected and can only be taken as a combined package due to interdependencies in the material. The summer school is intended for students with a background in communications and networks engineering and is given in form of 30 hours of lectures.

This Summer School is jointly organized by CERTH / University of Thessaly (Leandros Tassiulas) and University of Catania (Sergio Palazzo)


The summer school will be held at "9 Muses" Hotel, in Santorini Island, GreeceThe "9 Muses" hotel is located at the Perissa sea village, at the southeast side of the island. The Santorini island is easily accessible from Athens by plane. More information about Santorini can be found here.


All attendees can reserve a room at the "9 Muses" Hotel by contacting Mavroedis Travel Agency either by email at (contact person: Ms. Xanthi Mavroedi) or by phone +30-23510-35735 with the note for the Summer School in 9 Muses hotel, Santorini, Sept.25-29.

There exist two options: (i) single-occupancy room for a rate of 120 euros per night, including breakfast, (ii) shared (double occupancy) room for a rate of 63 euros per night, including breakfast. All attendees should declare their option upon contacting the agency for room reservation. Please reserve a room before September 20.


The Summer School is open to both NEWCOM and non-NEWCOM members. For NEWCOM members that register before September 20, 2006 attendance is free. For Non-NEWCOM members, there is a registration fee (300 euros). For NEWCOM and non-NEWCOM members that register after September 20, 2006, there is a fee of 50 and 350 euros respectively.

Important: All attendees please fill the following registration form and return it to the email address:
