In the UK O2 have there Airwave divsion of the network, which allows the emergency services to continue to communicate with each other, if distator stucks, for example during the london bombings, the networks were jammed in london and only airwave was still active, since its only for the emeregency services to use.

Thnx for ur answers.
@Batesie, Yes PTT always worked fine but GSM. Unfortune this service in Peru is very limited in coverage and mainly to business man.
@QVGA, some towers fall down in Ica (300km to the south) but in Lima no one, and Lima-Lima communications were down too. Lima population is about 8millions and Ica 8thousands (national mobile penetration around 50%) so heavy number of calls was the factor surely.
@MrMiyagui, thats the question, every mobile operator must have an emergency way to keep important communications? does it exist in Peru? People in Ica are in day 2 after earth quake, no electricity, no water, damaged roads... Mobile calls are better now, not ok but work. Its ironic that main way of communication until now are the solid old radio stations but no the modern ways as mobile

Oco, I think it's the mobile companies, who have been nudging people to buy phones and increase market, they forgot to implement their services and towers in a proper way. We were not prepared for this.

We once had a network failure in my country. It turned to be a fre hour for all. Call were made free of charge and I was on air for more than twelve hours. As soon as the network was congested, it was more of a christmas bonous as sms also turned to be free as well.

well this problem here in Peru is not new, i remember that in a normal day sometimes i call someone and the network is just overloaded, specially with certain operators.

actually besides from radio, what is really helping in the damaged area is satellites communications. hopefully fixed phones in Ica are now 90% working, so are mobiles in this area.

Well if the power and water are out chances is phones will be too, the cells do need power too. But mainly in disasters if the network isn't physically damaged its just the conjestion. Networks can't be designed to accomodate everyone all at once, even in normal times there is a certian regection ratio so go figure when everybody wants to make a call. And of course when applicable higher priority phones are given access first.

There are lots of other things that you have take in to thought.

Networks actualy dont get overloaded.

The networks are designed to handle traffic, however the networks also carry what they call spare capicity.

When somehting happens, the networks either use the extra capicity or part of the network is shut down to stop something else happening.

The emergency services dont just use airwave they also use normal mobile systems as a secondary system (UK)

If there only 2 phone boxes and 100 people waiting to use them this is not called overloading but just busy and you have to wait your turn.

Same with the mobile world and this is why you may get network Busy.

Hope this makes sense
