Security alarms, medical alerts and other devices could fail once the older wireless services cuts off.
AT&T's planned shutdown of its 3G network Tuesday has sparked fears that home security systems, medical alert monitors and a range of other devices will stop working.Carriers have previously retired networks, but this transition is proving more complicated because the pandemic hindered companies that rely on 3G services from making upgrades. Plus, there are just more devices to manage.
As much as 10% of all public school buses across the country will lose GPS and communications services, according tobus riders that more than 650 prediction display systems at bus shelters that rely on AT&T's 3G service will stop displaying real-time information.An alarm industry group says roughly 2 million devices powering burglar intrusion systems, fire alarms and personal emergency alerts will go offline.
"If you roll the dice, maybe nobody has a problem in the first day or the second day or the third day," Feld said. "But eventually someone’s going to have a problem where they will need that alarm."
