Anyone know how often a cell phone will ‘ping’ the tower, someone said every few seconds, I thought it was in minutes.
This is how i understand how it works. The phone pings the tower basically saying I’m here and I’m listening for you to tell me if a call is coming it. The tower responds listen to frequency xxxx, and the phone does passively. The tower announces on frequency xxxx to all the phones listening. If a phone hears its ‘name’ called it will also be given a frequency for the call (actually 2 frequencies talk/listen) and will go to that to complete the call. In the above the carriers left a empty space in that listening frequency which they wanted for potential future use. That reserved empty space is what is used for txting. So this is why txting is so fast, it uses the same method as to get your phone to ring, that being passively listening.
Txting was a form of mobile email (actually you can usually txt to email and email to txt), it was smaller and less functional but that made it great for a cell phone but not really needed for landlines. Landlines used computers with modems to accomplish essentially the same thing as txting, so there was no pressing need for landline txting.
Txting,while still tied to email, really has taken on a life of it’s own, but the land line phone is dieing out, plus broadband internet, which is expanding, can handle txting, so there is no pressing need to add this function to landlines.
