VoLTE Infrastructure Market Revenue Declined 10 Percent Y/Y in 1Q 2019, According to Dell'Oro GroupREDWOOD CITY, Calif., May 29, 2019 /PRNewswire/ -- According to a recently published report from Dell'Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, Voice-over-LTE (VoLTE) infrastructure market revenue declined 10 percent year-over-year (Y/Y) in 1Q 2019. Huawei ranked no.1 for the first time this quarter. "Many service providers are not aggressively promoting VoLTE even as LTE subscriptions continue to rise," according to Dave Bolan, Senior Analyst at Dell'Oro Group. "Several factors can keep service providers from offering VoLTE. One factor is the capital cost, another is geographic coverage. VoLTE requires good RF coverage to work properly. Therefore, service providers that offer LTE at higher frequencies need more cell sites to get the same quality voice coverage," continued Bolan. "The tipping point toward VoLTE will be 5G Standalone networks. Voice over 5G will also use the IMS Core, but if 5G coverage is weak, then voice calls can only fallback to VoLTE since circuit switched fallback is not supported in 5G. Service providers are slowly beginning to recognize this and are taking the adoption of VoLTE more seriously," Bolan added.>
