CWTEC 2023: The unavoidable complexity of future wireless networks?

Brought to you by Cambridge Wireless

The introduction of new mobile network generations, new spectrum bands and new antenna technology has added complexity to deployed networks. Work on defining the next generation of mobile networks is underway, is this the time to rethink mobile networks?

Registration for this event is now closed.

About the event

Through in-depth technical presentations, CW TEC 2023 will explore the complexity of future wireless networks, with sessions covering:

How complex are current mobile networks?

  • What is the complexity?
  • What has driven the complexity?
  • multi-RAT, multi-Band,
  • M-MIMO,
  • Multiple backhaul options

How do we deal with today’s complexity?

  • Managing the complexities Tools & techniques
  • What short term techniques can help to manage the situation?
  • Intent based network and service management
  • Wi-Fi / Cellular integration
  • Application of AI

What are the future technologies that are making it simple (or not)?

  • What long term/distributive technique are on the horizon?
  • Integrating space and airborne platforms (LEO/HAPs)
  • Even higher frequency spectrum (THz)
  • Open architectures (Open RAN)
  • Cell-less architectures
  • A new 6G RAT?
  • Spectrum sharing?
  • Neutral host in-building
  • RIC (non-real time, near real time & beyond)

The day will conclude with a panel introducing insights from adjacent industries such as the energy sector, railway signalling, TV broadcasting – how have they dealt with complexities and improved infrastructure?

How complex are current mobile networks? - Vicky Messer

Session chair – Vicky Messer, VP Product Management, Picocom UK
How complex are current mobile networks?
Exposing the reality of current network deployments; multi-RAT, multi-Band, M-MIMO, many backhaul options…

09:45

Talk 1 - Network architecture - Andy Sutton

Andy Sutton, Principal Network Architect, BT
Where did the complexity of future wireless networks come from? What has happened since we launched 2G GSM with a single technology, single frequency band and a single operator site? This talk will review the evolution of digital cellular site design and explore how the complexity has come about. To do this we’ll explore radio access technologies, frequency bands, antenna systems, RF transmission lines, site sharing and mobile backhaul, we’ll also look to the future to consider how site design will evolve through RAN architecture evolution, including optimisations of today’s D-RAN and deployments of C-RAN with traditional approaches, or vRAN and Open RAN.

10:10

Talk 2 - Normal Accidents – Living with high-risk technology - Moray Rumney

Moray Rumney, Director, Rumney Telecom
The limited debate on how brittle our technological world is becoming needs to be addressed or we risk sleepwalking into catastrophe. This talk is based on a 1984 analysis of high-risk technologies by Charles Perrow of Yale. His thesis is that when systems become sufficiently complex and tightly coupled, failure will be unexpected, incomprehensible, uncontrollable, and sadly, unavoidable. Blaming the operator is common, but Perrow’s conclusion is that failure is not unlucky or abnormal but inevitable based on design. The solution is not more risk mitigation features which add complexity but to return to less complex systems that are inherently robust, less efficient, and less vulnerable to failure and attack

Managing today’s complexity - John Okas

Session chair - John Okas, CCO, Real Wireless - Managing today’s complexity
What are the tools & techniques for dealing with today’s complexities? What short term techniques can help to manage the situation?

11:25

Talk 1 - Managing complexity & predicting future capacity upgrades - Peter Love

Peter Love, 4G/5G Densification Architect, Nokia
What if we could predict the future? The overwhelming majority of complexity in current mobile networks is driven by the need for ever growing capacity. In this presentation we will we be answering the following questions.
• Why is capacity growth important and why is it difficult to keep up?
• What is the current arsenal of solutions on the table today to help?
• How to decide what solution best fits the network expansion whist being a justifiable expense?

11:45

Talk 2 - Supply Chain Diversification - is it just another name for complexity? - Nick Johnson

Nick Johnson, Head of UKTIN
Economics tells us that monopoly of supply is a bad thing, and in the context of telecoms we seem to be very close to it. Government proposes diversifying the supply chain as a remedy. Industry imagines promoting another large vendor to fill the gap. How can telecoms innovation help the industry meet policy, manage complexity, be affordable, perform well and make common sense all at the same time?

12:05

Talk 3 - AI-native 6G – rethinking network architecture - Yue Wang

Yue Wang, Head of Group, 6G Research/SRUK, Samsung
The presentation will discuss the challenges the industry is likely to encounter as we advance towards an AI-native network, and highlight the need to rethink the design and architecture of next generation networks to support the convergence of communication, computation, and intelligence in the 6G era.

12:25

Talk 4 – CISCO - Simplifying Wi-Fi Operations - Mark Grayson

Mark Grayson, Fellow, Global Technology and Standardization Group

The presentation also includes the type of use cases a future network needs to address, something about required network capabilities, as well as some of the technology components, ending in a high-level architectural view.

14:35

Talk 2 - Integration and Interoperability - Maria Lema

Maria Lema, Weaver Labs

Talk 3 - Intelligent RAN Architecture - Professor Rahim Tafazolli

Professor Rahim Tafazolli, University of Surrey
The talk will give an overview on what is expected for 6G to deliver and more notably the 6GIC vision and strategy of 6G requirements and research challenges. It will propose new RAN architectures that will simultaneously achieve energy and Coverage efficiencies. The idea is based on intelligent Network of Networks in solving an important societal challenge of Digital Divide.
