In a Linkedin post, Rakuten Symphony CMO Geoff Hollingworth says 5G has been a failure, that it will never achieve ubiquitous coverage and it’s time for the mobile industry to invest in customers rather than networks:
5G is a failure. We build technology to deliver a promise, the promise made was commercial. If that promise is not delivered then it has failed. If that promise is delivered but the cost of delivery is prohibitively expensive versus the return, then that technology is a failure. Currently the promise has not been delivered and there is no line of sight to delivery.
I do not believe the market is going to deliver on this promise further down the road, the networks do not work this way. 5G will never have ubiquitous coverage, and this is getting worse. We can get closer to ubiquitous coverage as a network of networks but then all the complexity embedded in 5G for advanced management of the network is a cost. There is never only one “G” in a market, there tend to be at least 3 at any moment. Each G takes time to retire, from a customer, device, and ROI point of view. APIs cannot get deployed universally and by the the time networks are universal the next G is starting to be rolled out. We are still waiting for “real 5G” but even when it shows what will it translate to commercially? Will it arrive before something labeled “6G” is starting to roll out?
“The current cost for 5G is breaking the bank, to the extent where 6G might not be affordable. None of this is good for an industry that is supposedly powering the global GDP and defining the future state of all countries.”
Of course, we agree as we’ve been pounding the table since the 3GPP Release 15 pre-standard version of 5GNR was introduced in 2018. The “real 5G” must include standardized 5G SA core network, URLLC that meets ITU-R M.2410 performance requirements and harmonized frequencies.
“We are already repeating the narrative into 6G with the same concept of ubiquitous coverage mindset. We are not segmenting for actual coverage and actual market reality when comparing to cost, time, and need,” Hollingworth warns. “We must embrace that there are other better ways to solve for coverage, depending [on] the use case and the coverage type required. We have less of a coverage problem and more of a seamless access problem, as one moves from indoor to outdoor city to outdoor suburb to rural.”

Future Network Trends -AI native and cloud native operations:
To see future network needs, there is a need to understand future AI software design patterns. We now see these appearing and they are different from what we have seen before.
They depend on large data streams where the data and interpretation has time sensitivity.
Compute is distributing to where the data is rather than bringing the data to where the compute is.
This forces distribution of models and software to where the data and compute is, and overhead must be kept to a minimum and automation must be maximized to be cost effective.
There is need for rapid iteration and continuous fine tuning of the models and algorithms as more data is analyzed and performance improves.
The first applications with these design requirements are the 5G++ network architected functions. The test of the industry is whether the software can be adopted with true AI native, cloud native operations or whether they will be deployed traditionally. If we succeed in deploying a true hyperscale operation for our own software we can take our tooling and knowledge, and expand it to support any application and service.
Now there are many networks that devices can connect to, and 80% of the time traffic does not travel through cellular networks at all. In markets with high fiber penetration Wi-Fi connectivity and latency has higher performance than cellular, especially indoors, where higher frequency spectrum no longer travels inside buildings, especially those with reflective sustainability materials.
We previously solved as if cellular was the only way to solve all the problems. We must embrace that there are other better ways to solve for coverage, depending the use case and the coverage type required. We have less of a coverage problem and more of a seamless access problem, as one moves from indoor to outdoor city to outdoor suburb to rural.
