On February 22, AT&T plans to close the book on 3G to make room for the upgrade to 5G. It says it has given companies and consumers that rely on their networks three years’ notice about this, but the Alarm Industry Communications Committee (AICC) wants an extension. In a filing to the FCC earlier this month, communication organization Public Knowledge claimed that factors like the global pandemic and the semiconductor shortage introduced difficulties in upgrading from 3G. In an FCC filing from earlier this week, AT&T points out that alarm company ADT has already upgraded nearly all of its 3G systems.
Along with AT&T, T-Mobile will shut down its 3G network at the end of March, and Verizon will follow suit at the end of the year.
