Much of the ongoing discussion around 5G is focused on use cases: wireless broadband to the home, in-vehicle infotainment, immersive event experiences, truck platooning, remote health care, smart cities and smart factories to name a few.
Mobile networks and cloud packet core developers are working on the new mobile standards and technologies that will make this happen. Radio access network (RAN) technology is evolving from distributed to centralized to cloud architectures. Solutions are being developed to push content and some elements of core processing closer to users: Multi-access edge computing.
Operators will ultimately use a variety of architectures for 5G. Those new architectures are not going to work without an overhaul of what we call the anyhaul network: a mix of mobile transport technologies – including fiber, microwave, and GPON.Low latency is essential for centralized and cloud-optimized RAN architectures.
High-throughput IP routers with a variety of 1/10/100 GE, TDM, and SONET/SDH interfaces are required to provide high-throughput, secure, reliable routing for any-to-any connectivity over any network topology. Operators need 10 Gbps cell site and 100 Gbps network links, multi-terabit throughput capacity, and high port densities at every node. Carrier software defined networks (SDN) provide the functionality needed to provision end-to-end network services over multi-layer wide area networks.
