Mobile operator EE has completed the migration to a new national IP/MPLS core network which underpins the delivery of its faster 4G data services.

EE launched its 4G service in October 2012 and uses the same network to provide 3G services. EE's 4G coverage is said to reach 72 percent of the UK population, with 3G coverage reaching 98 percent of the population, according to EE.

EE has signed up 3.6 million 4G subscribers, with sales of 4G plans now outstripping 3G. With such a fast rate of 4G customer adoption, the network had to be underpinned by an MPLS (multi-protocol label switching) platform capable of providing a higher performance at scale to serve data-hungry 4G users.

The MPLS network has been delivered using Juniper Networks' SDN-ready MX Series Universal Edge Routers. Used with the established Juniper Networks Junos operating system, EE says it has a network that will increase automation and deliver services at scale. This includes bringing new MVNOs (mobile virtual network operators) online quickly and managing multi-service IP interconnects with other service providers.

Peter O'Donnell, head of transport network design and planning at EE, said: "We predict 97 percent of our customer base will be using 4G devices by 2018. The Universal Edge technology provides EE with all the capacity and performance head-room that it needs in the medium term, and it has a strong development roadmap so our investment is sound."
