- the pager is limited, geographically, in just how far a toned-out page will be received, whereas a cell phone, with its unlimited towers, can receive the notification no matter where you are;
Generally, if im off-duty but standing by for calls, im well within the coverage area offered by my pager... And despite what the big three cell carriers would like you to believe, they are nowhere near reliable coverage in central Pennsylvania. Cellular is 100% reliable 65% of the time.
text messaging sent out by the agency is, in itself, a cheaper and more convenient alternative to receiving notifications. There is also apps available to co-ordinate communications between department and agency members via text messages, too.
I agree with you on this, it has made interagency communications a breeze but this was never done over our dispatch anyways. Others may have.
if the "sound" of the tones going off and listening to the Dispatcher is what gets you up, then your agency...or members...signing up for such things as "eDispatch" will fill your bill, which will generate a phone call to your cell phone, with the tone/voice message that was sent and, again, with no geographical limitations.
The sound of my tones isn't what usually wakes me, it's my pager. The little ding my phone makes when a CAD is pushed to it does not. As for our County, I also get more info over the voice page vs CAD push to my phone, YMMV. And again for the geographical issue, I feel if you're so far away from your coverage area that you no longer hear your dispatch center, you're not really in a position to respond.
The issue of using phone apps to replace pagers, there's usually no further info after your notification. Who responded? Did additional info come in after the initial dispatch? Did a numerical change in the address? Did another unit come available and swap assignments with you? Some places may do it right, but I imagine most don't.
Also, take into account that the Counties that dispatch over radio generally own the infrastructure that does the paging and voice dispatching. So in the realms of public safety, its an entity they own and maintain and in turn, they know its reliability in the event of a disaster. While cell towers are generally well-maintained and backed up, they are still owned by an outside entity are still used by the lay public, and are prone to failure.
