At the moment, most of our users are based in the major cities where the carrier coverage is great, so we don't need to worry about them being out of coverage.
Shortly, however, some will be travelling to various parts of the country where coverage may not be that great and I was wondering how this would affect our BES service to these BB users (we are running BES 4.1.7).
Let's say a BB user is out of coverage. How does the BES "know" not to keep trying to send messages to them?
On this same level, could someone clarify the various signal 'bands' there are? From the users who have gone out of coverage there seems to be:
3G (best) > EDGE > GPRS > gprs > GSM
Am I correct? And they need at least GPRS for BES functionality to work (lower case gprs means that the device is just waiting for BES-enabled GPRS to work)?
But I always thought GSM was the band that all of them (incl 3G worked at)?

"When a BlackBerry smartphone is unable to receive messages (for example, if the BlackBerry smartphone user is out of network coverage or the radio is off), the messages remain in a queue on the BlackBerry Enterprise Server until the BlackBerry smartphone connects to the wireless network"
So I guess that that BES server needs to recv some sort of notification from the wireless (carrier or RIM?) network that the device is back in coverage again. Do you know how this works? Is the communication regarding out of coverage/ in coverage devices:
i) Between BES server and RIM NOC
ii) RIM NOC and Carrier network
iii) BES server and Carrier network?
