With the announcements by the Korean mobile service providers and AT&T in the US, turning up 5G service in late 2018, this might be a good time to pause and reexamine the road to 5G – how we got to this point, and where 5G is going in the future. There have been many twists and turns on the way, and I am sure there will be many more. A few of the twists we have recently seen discussed in the media revolves around the definition of 5G.

I wrote an article published on RCR Wireless – The Twisted Road to 5G – the primary focus are the packet core and the RAN, and I discussed 5G based on the 3GPP specifications. Here are some highlights of the articles:

  • 5G Vision and Milestones to Date – The 5G System has come to be known as 5G Standalone or Option 2 for a 5G network architecture (Figure 1). In addition, a wireless system must work over certain spectrum and a 5G spectrum has been defined by 3GPP as well. 5G frequency bands for UEs…
  • Twist or Turn to 5G?  The industry coalesced around the 5G NSA E-UTRA-NR Dual Connectivity (EN-DC) architecture as shown in Figure 3 for early deployments of 5G in 2019. As it turns out, MR-DC is a way to deliver more bandwidth by combining the capacity of the 4G RAN and the 5G RAN …
  • 5G Core is Key to Achieving the 5G Vision – The 5G Core (Figure 4) is designed to be a service-based architecture (SBA) to provide a resilient, efficient, and flexible network to meet the requirements of all of the 5G uses cases (eMBB, mMTC, uMTC/URLLC, and FWA). The SBA is designed to…
  • Path to the 5G Vision – At a minimum, 5G can be UE devices (e.g., 5G hotspot or 5G smartphone) and an access network (e.g., 5G NR) that utilizes the defined 5G spectrum and is defined by 3GPP that leverages the EPC. Technically, the network would be described as …
