-=> Brian Lingard said to Al Feyen about, Cell <=-
 BL> Your cellular phone will probably do a check-in with the network
 BL> every 30 minutes or so.
 BL> I base this on the regularity of my phone checking in to the
 BL> network when I have it near a radio and get a little interference
 BL> on the radio from the phone transmitting.
 BL> The network can probably control this by sending out a roll call
 BL> request.
 BL> Your phone also sends an identification when you turn it on.
Only once every half hour?  I know it varies by company,
but a half hour between check-ins seems like a long
interval.
Not that I doubt your word or your method.
It must vary by call volume, you ether live in a high
volume area, or a low volume area.
Most other people I've talked to about this clam times as
low as five seconds or as much as 2 minutes.  No one else
was even closes to half an hour.
 
Blessed Be
