REDWOOD CITY, Calif. – February 19, 2015 –Dell’Oro Group, the trusted source for market information about the networking and telecommunications industries, announced today that the Evolved Packet Core (EPC) market grew significantly year-over-year, turning in nearly 150 percent revenue growth in the fourth quarter 2014 versus the year-ago period.  Driven by rapid subscriber growth on Long Term Evolution (LTE) radio networks, the EPC segment continued to drive overall market growth, as Traditional Packet Core revenues declined.

“There are two interesting points to note this quarter—namely that the Asia-Pacific region now represents the largest segment of the evolved packet core market.  Recently, this has been driven by Chinese service providers’ significant expansion of their LTE networks,” said Chris DePuy, Vice President at Dell’Oro Group with responsibility for Wireless Packet Core coverage.  “The second point relates to another interesting trend, Voice over WiFi (VoWiFi).  While market adoption of this technology is primarily driving IMS spending, it is also benefiting the packet core market with spending on devices such as the Evolved Packet Data Gateway, or ePDG, which is an integral part of the VoWiFi delivery infrastructure and allows for continuous call connectivity when the user moves from WiFi to cellular coverage,” DePuy explained.
