Thessaloniki, May 22nd ’08
First International
Conference in North Greece
on EMF Healthy and
Environmental Impact
Is the electromagnetic
pollution necessary in urban
areas?

1 Microcelle UMTS+GSM+DCS
2 La microcella 8 è stata simulata in corrispondenza a due posizioni distinte su pali contigui; nel calcolo dell’esposizione per la microcella 8 vengono calcolate
contemporaneamente le due collocazioni suddividendo 2 UMTS + 1 GSM sul primo palo e 1 UMTS + 1 GSM + 1 DCS sul secondo

THANK YOU FOR YOUR ATTENTION
• THERE ARE IDEOLOGICAL AND
POLITICAL REASONS BUT INDUSTRIAL
TO DELIVERY WORLDWIDE WARM
CELLS TO PROVIDE MOBIL PHONE
SERVICES. 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.
