We hate it when a company presents a case study but is unable to mention the operator. Still, we also must give credit for the information assuming the vendor is being as honest as it can be with their assessments —there is a clear conflict of interests when you explain your own successes. This one, however, proves a few things: first, operators are moving forward with SDN, as they need its flexibility; second, SDN proves to be very useful to handle existing networks IP/MPLS or microwave links. SDN is becoming a critical architecture for the future of telecom networks, and it seems the trials period could be reaching the end of its cycle; commercial implementations are about to begin.
We have already established that many corporate blogs are just trying to promote something, meaning: their intent is not purely to inform, but to redirect users towards other assets. This misleading headline suggests there is much more meat on it than there actually is. The truth is that it is pointing to a report from RCR Wireless, and, as we have stated in the past, if there is a white paper behind a mild blog post, it is still our duty to alert about potentially useful content. In any case, the post raises an interesting question, which is how operators can implement a C-RAN architecture while improving —or at least not degrading— user’s quality of experience. The headline had a ripple effect in our heads, leading us to another question we have already asked with NFV: Do operators really know why the need C-RAN for?
Brazil’s economy is going through a recession, but its mobile operators are beefing up their 4G networks
Some are arguing that Brazil could be experiencing the worst economic recession in its history. This could be true but mobile operators have been expanding its 4G networks to improve all its metrics: coverage, speed, capacity and latency. It seems that the World Cup and the Olympics have had a tremendous impact on the telecom infrastructure, now we hope those reports that correlate mobile infrastructure with economic prosperity are right.
There are technologies, such as LTE-Direct (Release 12) that sound like a great idea, but the industry does not seem to care much about them. Some technologies successes are clearly dependent on device manufacturers and, when this is the case, operators have a tough time to decide when it is the right moment to invest in them. It is happening with LTE-Broadcast and also with LTE-Direct. This scenario is not going to change any time soon as the market for devices is so competitive that for a manufacturer to add extra cost to its own devices with an extra feature, there must be a clear user demand for such feature; otherwise, they have no incentive whatsoever. But users have no way to try a new services if device manufacturers do not offer compatible devices; network operators have no incentive to launch the technology. If this feels like the catch-22 paradox, it is because LTE-Direct is a catch-22 situation.
All of us try to play with headlines and, in this case, the headline is quite misleading because the author says he is going to predict what claims to be unpredictable. In fact, the blog post is quite interesting in its predictions, how 5G will progress in 2017 and what areas are the key focus to many companies, especially Ericsson and Qualcomm, as stated by the post. What is important about this blog post is that most of the author’s claims are backed with sources and links to other articles; this provides more credibility to his arguments: 5G is all about connected cars, IoT, MEC, Fog Computing, and network slicing.
It is a brave thing to state, at least these days, that a telco needs to think about a new technology in terms of “revolution” and not “evolution”, as the term “revolution” implies that what has been done before is useless. And remember, operators do not like “revolutions” because they want to use legacy systems as much as possible. Hence, infrastructure providers always talk about “evolutions”; not im this case. Leaving the author’s bravery aside, the following blog post is an interesting one, worth reading, as the 5 silver bullets provided are indeed useful to make sure mobile operators dimension their 5G backhaul infrastructure efficiently. The problem is most operators will avoid any infrastructure revolution as most of them will use current backhaul networks as much as they can for 5G traffic.
This is one of those blog posts —quite common these days— that provides just enough information to be picked up by our radar, but that it would not be worth reading if it wasn’t because it is also promoting a webinar on 3G and moving RAN to the cloud. The topic is interesting because we always think about RAN and the cloud for 5G as if current technologies could not benefit from the cloud flexibility and scalability. Thus, we thought it was worth letting you know about it. And, remember, just because the webinar is on 3G, it does not mean you are walking backwards.
More predictions are coming our way and it does not seem they are going to ever stop. As we have mentioned in previous reviews, our radar is picking them up because most companies are taking the opportunity to write about what’s coming mostly because they have not much to say at this stage. This one is mixing things from mature markets such as the future deployment of 5G —not in 2017—, with emerging markets, which are, in fact, still deploying 3G; in between, the author throws in net neutrality. If you have the stomach, you will be able to digest it.
Just read it. There is not much we can say about it. The industry keeps telling operators that 5G will allow for new services and even though such statement is not false or wrong it is incomplete. The new wireless technology will be a driver for new services, which is different to say that operators should be the ones addressing all of them. Instead, operators must use their resources to turn their business into platforms for others to join, create and share the revenue.
