Helo,
in fact nothing more than a classic commercial geolocation server as it can be 
used in opt-in or automatic way for car fleet management, for example. 
We did sth like this integrating a probe software inside a phone, but you can 
ping (paging) very well a device directly from a server every x min. (there are 
even commercial offers from telcos)- nevertheless, to do it on all customers at 
once will break down the network...

Objet : [mobile-society] Mobile tracking

Dear all,

There have been some interesting articles on the tracking of mobile phone 
customers. A German member of parliament has a loaded his location information 
so that it is possible to track his movements. It is also possible to see the 
cell tower he is connected to and there is an icon showing whether he is making 
a call. As far as I know, you cannot see who he is calling, the content of 
texts etc.

There has been some discussion about the telecomm operators tracking people. It 
is clear that they track their subscribers since they need to know where they 
are in case they are called. As I understand it, the phone "pings" the system 
every few seconds to let the system know where it is. If the phone (and its 
owner) are moving, this information is also used to alert the different towers 
as the signal degenerates in the one and grows stronger in the other.

The text in the Fast Company article makes is all sound quite nefarious, and I 
suppose that it could be if it were misused. However it is a necessary part of 
the system.

Rich L.
