Verizon Wireless plans to shut down its 2G CDMA2000 1x network by 31 December 2019, reports Fierce Wireless, with the operator said to be working to transition its voice calling services onto its LTE network via voice-over-LTE (VoLTE) technology. Verizon noted in April 2016 that 92% of its wireless traffic was carried over its LTE network, and has reportedly said that mobile users typically replace their phones every 2.5 years, therefore expecting the majority of its CDMA200 1x subscribers to have moved to VoLTE-capable phones by 2019. The cellco, however, will consider postponing the 2G technology closure until 2020 if subscribers need longer to migrate to its LTE network. ‘We will not abandon a single customer,’ commented Verizon spokesman Chuck Hamby, adding: ‘We will work with each of the customers one-on-one. Should there be stragglers, we will continue to work with them.’ Verizon is also refarming its 3G CDMA2000 1x EV-DO spectrum to use for its LTE network, while Fierce Wireless notes that rival operators AT&T, T-Mobile and Sprint have also closed down older networks in recent years, having shut down their respective Leap Wireless’ Cricket CDMA network, MetroPCS’ legacy CDMA network, and WiMAX network.
