"CARRIERS NATIONWIDE CAN NOW legally bid adieu to the legacy analog networks that the Federal Communications Commission required them to keep online through Feb. 18.
AT&T Mobility and Verizon Wireless will be shutting down their analog networks this week, while Alltel Corp. is taking a phased approach to the shutdown that will be complete by the end of September. The three companies are the largest carriers that will be turning off their analog networks, but many smaller, rural-based carriers have the same opportunity before them."
