Thessaloniki, May 22nd ’08 First International Conference in North Greece on EMF Healthy and Environmental Impact Is the electromagnetic pollution necessary in urban areas? Dr. Prof. Livio Giuliani Dr. Ing. Francesco Boella National Institute of Occupational Safety and Prevention Venice - Italy Exposures due to previous plants in Don Sturzo Park area (Venice) A new cositing is to be implemented in the middle of the park.

IN FACT THE ARCHITECTURE OF A NET BASED ON MICROCELLS IS MORE EFFICIENT IF THE INTERCONNECTION WITH FIBER IS HIGH. THAT WAS THE OPPORTUNITY TO EMPLOY THE WIRE NET IN EUROPE.
