"5G: Review of 5G Technology Readiness and Commercialization", is a Global Outlook Report that gives an overview of the emerging 5G standard and the main market requirement trends worldwide with a competitive insight to players driving 5G deployment. With the first 5G radio equipment now available, initiatl 5G deployments have begun, led by operators in Korea, Japan and the U.S. The introduction of the first 5G mobile handsets later in 2019, as well as further evolution of 5G radio and core specifications, will drive massive adoption of 5G beginning in 2020.
While pre-5G, pre-standards deployments have defined the 5G era thus far, significant hardening of standards related to both radio and core innovations took place in 2018. After completing the first 5G standard in December 2017 for 'non-standalone' 5G new radio (NR), the 3GPP, which defines the standards governing cellular technologies, approved the standalone version in June 2018. The non-standalone version enables 5G NR to be deployed on top of an existing LTE core; however, the standalone version enables operators to build greenfield all-5G networks.
Meanwhile, operators continue to refine the 5G core based on the service-based architecture (SBA). Building a 5G core will be crucial to enabling 5G-related features such as network slicing, but SBA represents a radical change in network design. The reference architecture for SBA is well defined, but the transition will be rocky. As a result, vendors are working with operators to enable a smooth transition to SBA-based 5G core.
5G transport requirements dictate significant increase of bandwidth to the RRU of 10 Gbps and more; backhaul connectivity to CU will scale to 100 Gbps. 5G advanced use cases have very stringent synchronization and latency requirements as well, and vendors need to offer solutions that fulfill these 5G transport requirements cost-effectively, while also taking into account physical constraints (space and power available). Vendors should also take into account interworking between 5G transport and 5G core, and deploy solutions that serve other network domains as well (fixed access, carrier Ethernet, etc.) to optimize costs of 5G transport deployment and operation.
The report identifies the technology underpinning the move toward deployment of 5G networks. The report focuses on key developments across the radio, core and transport network domains. The report also identifies the established and emerging vendors participating in the 5G market and identifies important networking innovations being developed to enable network operators to achieve 5G's full potential.
