This report answers the following questions:

  • Will virtualisation of the 5G radio access network truly enable significant gains for operators in the medium term?
  • What impact will dynamic spectrum management have on 5G?
  • What is the timetable for a standalone (SA) core network, the gateway to true 5G?
  • Will operators no longer be dependent on traditional equipment suppliers? Who are the RAN mavericks?
  • What impact will new entrants from the US have on the RAN market?
  • Which operators are spearheading the adoption of 5G wireless network virtualisation?

List of tables and figures

2. 5G and new network architectures

  • How SDN works
  • How iNFV works
  • Cost comparison between D-RAN and C-RAN on the TD-SCDMA network operated by China Mobile
  • Cost comparison between D-RAN and vRAN over five consecutive year in a densely populated area
  • Allocation of required means to services by slice
  • Comparison of the services’ different speed and latency requirements
  • Pros and cons of the different types of spectrum
  • How calling networks have evolved to accommodate more complex and demanding uses
  • An approach disaggregated from the RAN makes it easier to perform rollouts and increase the network’s density

3. Initiatives

  • One of the transformations sought by network virtualisation is the ability to be free of vendor lock-in/lock-out
  • Main alliances devoted to promoting the development of open vRAN solutions
  • Huawei, a major absentee from the two main Open RAN alliances

4. Rollouts

  • China Mobile’s ongoing RAN developments
  • Features of Rakuten Mobile’s RAN
  • Telefónica’s current RAN developments
  • A number of vRAN and Open RAN initiatives, still in the trial stage
  • Vodafone UK’s current RAN developments
  • Pros and cons of NSA and SA
  • mmWave bands, a plus in the medium/long term
  • Pros and cons of open and non open vRAN solutions
  • A horizontal and vertical disaggregation of the RAN
  • Pros and cons of Open RAN depending on population density
  • Expected economic benefits for mobile operators adopting vRAN solutions

5. Conclusions

  • Mobile operators’ adoption of virtualisation in the RAN
  • Five veteran suppliers’ (Ericsson, Huawei, Nokia, Samsung, ZTE) share of the RAN market
