5G Core Summit – Cloud, Fog, Private 5G and Initial Deployments

At the beginning of November, we took part in the 5G Core Summit by Informa and Knect365, a virtual conference, on which I’d like to shed some light.

5G Core Summit

The conference’s main areas included: 5G use cases and ecosystem development, network cloudification, edge clouds, and network slicing, trials and lessons learned from initial deployments, specialized use cases, private networks and practical aspects of the first implementations, evolution strategies, and alike.

We had the opportunity to get some insights into various topics around the 5G Core Network. For me, however, not this was the most important concerning this summit. What was the most interesting, was to hear about the initial feelings regarding the first year of 5G deployments, about standalone (SA) network implementations, and cloudification of the networks that take part around the world. That was a reality check which took my attention.

One of the important aspects discussed in several panels and talks was the various use cases for 5G and the need for collaboration to realize those between the operator and the vertical / enterprise. This was raised as one of the key points to make 5G successful as being the vertical-based system, while each of the application is different and specific to a vertical, which require tailoring the solution and alignment between the requirements and offering, which is not always obvious.

Fog Computing and Private Mobile Networks within the 5G Core Summit Agenda

On our (RIMEDO Labs) side, we addressed two topics, namely Fog Computing (by prof. Hanna Bogucka) and Private 5G (by myself), which I’d like to elaborate on a bit more below. You can watch recordings of both talks in the videos below.

Fog Communications and Computing

On Day 2 of the conference, prof. Hanna Bogucka gave a talk on Fog Communications and Computing. Her talk included the following items: Fog vs. cloud vs. edge architectures for communication and computing networks, URLL communication and computing (URLLC&C) in 5G/6G networks based on fog architecture, computational intelligence in communication networks, cost optimization in the fog, and network „uberization”, AI for cost-effective URLLC&C perfection in the fog network.

After the session, prof. Bogucka joined Break & Live Video Q&As along with Yogaratnam Rahulan, 5G Innovation Centre, Philip Bridge, EE, and Christopher Silberberg, Omdia, where the discussion was around Cloud Native, Edge Computing, Network Slicing, and Monetization aspects.

Private Mobile Networks and 5G

On day 3 of the conference, I had my talk on 5G and how it fits onto the Private Mobile Networks concept, which covered background information on network and spectrum sharing mechanisms, 5G and its features that make it suitable to private mobile networks, various types of Private 5G Networks deployments with their pros and cons and how core network sits in those options, comparison between the 3GPP-defined Standalone Non-Public Network (SNPN), and Public Network Integrated NPN (PNI-NPN) as well as where private 5G suits its purpose and can be applied.

After the talk, I took part in a live Q&A session (which actually ended up being a panel discussion) with Guy Redmill, Redmill Marketing Associates, and Steven Ghoussain, Careem (Uber). The discussion circled around Private Mobile Networks, its potential, options and technicalities, network slicing, 5G applications, and use cases, as well as the language differences between the different parties involved in the current landscape.

Some of the conclusions were that to enable the true potential of private mobile networks it is required to get the ecosystem in place talking to each other with telcos, vendors, regulators (to allow local spectrum licensing), open initiatives (like Open RAN), application developers, and verticals. The variety of use cases require the discussions to take place between different parties, language to be unified, and integration being an important aspect to make this concept flying towards mass-scale deployments.

Final Note on the Presented Topics

Regarding Fog Computing and Communications, I believe this is an interesting topic for further research towards 6G extending the scope of potential processing places for AI and use cases requiring high performance. You can read prof. Bogucka’s post on the current trends in telecoms and IT, as well as on green communications, which relate to the „Fog” aspects.

Regarding Private Networks, in my opinion, it’s a huge topic for 5G to enable the full potential of 5G. I’m planning to write more about it on this blog soon, however, you can already find an introductory post on this topic in here.
