Remember the original analog cellphone technology called AMPS? That I first paid attention in 2004 the FCC said carriers may not remove AMPS cell sites before 2007.Landlines will work up until the time telcos are no longer responsible to maintain them.
My (not for long) employer was invested in AMPS and wouldn't let me pursue GSM or Verizon's CDMA. Sent letters to customers, "Oh, the FCC is only saying carriers may take AMPS offline in 2007. There is so much AMPS it will be around for a long time!"
First day they could take AMPS sites down, they started falling like a house of cards. Carriers could handle 10-100 more calls on the same precious bandwidth using GSM.
I was long gone in 2007. Later visited and found having lost the talent (me) to revise the PCB they hired a consultant to design an adapter board for the new data radio. I could have changed the original product's PCB for the new radio in a couple hours. But wasn't volunteering. They had the CAD software and original digital artwork. Just didn't have anyone competent to make the change.
