5G is the first wireless standard designed without the smartphone at the center — the 5G Radio Access Network (RAN), connecting subscribers to service providers, will be architecturally very different from past generations.
The core network, fundamental in managing and routing data, voice and video traffic, is also re-imagined in 5G. Network equipment manufacturers and service providers are faced with new technologies, architectures, access methods, applications, and traffic compared to past generations — they’ll need to troubleshoot never-before-seen issues in the rigorous R&D validation environment.
5G introduces higher frequencies (millimeter wave), wider bandwidths, advanced multi-antenna access schemes, small cells, and network slicing including network function virtualization, and orchestration. Given all this new technology, predicting and measuring the performance of the network in support of devices such as IoT sensors, smart phones, and self-driving autos will be challenging.
Keysight Technologies' subject matter experts, Kalyan Sundhar, author of "5G for Dummies" and Analyst Chris Depuy of 650 Group answer these questions:
- What are important technical service challenges faced in the evolution to 5G?
- How will infrastructure evolve for RAN and Core?
- What are the design and test challenges?
