5G networks are more complex to deploy and operate than their 4G LTE predecessors due to a number of factors. On top of the more complex radio and core architectures, 5G networks are also being deployed in virtualized environments. And there is an increasing focus on open interfaces between the key components in the 5G architecture, allowing mobile operators to combine components from multiple vendors into a single deployment.
It is important to understand that 5G does not require virtualization in order to be deployed; likewise, 5G does not need open interfaces; and ‘virtualization’ and ‘open’ are not synonymous with each other. But all of these trends are impacting the mobile industry at the same time, resulting in a perfect storm of disruption, innovation and change. The move to virtualized deployments started with 4G LTE – it is now accelerating. The Open RAN movement also started with 4G LTE but is starting to peak with 5G deployments. So, just as the major mobile operators, and new greenfield entrants, are deploying significant 5G networks, new options are available to them.
An added disruption comes from the enterprise 5G deployments – enterprises are now deploying their own mobile networks to support a wide variety of applications across all vertical industries. With the advent of new spectrum such as CBRS in the U.S., enterprises and organizations have access to spectrum allowing them to deploy and operate 4G LTE and 5G networks without the involvement of a mobile operator.
This eBook explores the concepts and technologies driving the transition in mobile networks from closed to open and from intertwined hardware/software products to virtual services that run on commercial off the shelf computing equipment. Interviews with leading executives covering the major issues, benefits and opportunities for the industry are included from Amdocs, CommScope, Intel, Mavenir, Nokia and Syniverse. And these leading vendors also cover a range of subjects in the accompanying articles.
