But the Analysys Mason report on the state of these markets, the snappily titled, Predictions for IoT: Investments in NB-IoT, LTE-M and new capabilities prepare operators for an active 2018, makes for interesting reading. In many ways, there has been a huge amount of activity in 2017 but, according to the research firm, that’s what makes 2018 so interesting. “The billion-dollar acquisitions or contract wins of previous years have been absent in 2017. That said, telecoms operators have been building out IoT connectivity networks, adding capabilities and working with the broader ecosystem. All of which should set the market up for an active 2018.” says the report.
One of the big questions facing the IoT market is what connectivity technology is going to be used. And here Analysys Mason sees a big split. In China, the drive is towards Narrowband IoT (NB IoT): it’s the technology that’s being supported by all three national operators and the government.
In the US, on the other hand, much of the impetus is towards LTE-M, where it’s being rolled out by AT&T and Verizon.
But, predicts Analysys Mason, there will be a change here. It sees Verizon as looking to support both technologies. For report co-author Tom Rebbeck, this is not a seismic shift in policy. “It’s not a big deal to support both technologies, it adds maybe 20% to the production costs.” The report points out that Telia is also supports both technologies. As Rebbeck points out, that’s a small price to pay to able to support global technologies. Analysys Mason does predict, however, that no firm will be launching both technologies at the same time — there’ll be one first.
One technology that’s not mentioned in the report is LORA, a third option for connecting IoT devices. Rebbeck says that this is a technology that’s stronger in Europe — particularly France, Switzerland and the Netherlands — rather than in the US or China. “Although,” he says, “there are pockets of LORA in other parts of the world: Dr Peng is doing things with LORA in China as is Comcast in the US.”
What is going to be interesting is to see how the operators react. We’ve already seen that Verizon is likely to be offering both but other providers could well take alternative approaches. “We could see different operators taking different strategies, whether that’s narrowband IoT or LTE-M or what,” he says. “This gives them a point of differentiation as it’s going to be hard to differentiate on price — this is a low-cost business.”
But, as he points out, there may be some specific elements in this. “Take the Apple series 3 watch, there’s a possibility that this will support LTE-M. If it does: that what would give an operator who promotes LTE-M a short term benefit.” However, this is not a likely outcome; as the report points out “This is a stretch given the status of the technology at the end of 2017, but LTE-M will support voice and streaming music (arguably a more important use case than voice) and uses lower-cost modules and, crucially, provides better battery life. In many countries, at least one operator will support LTE-M by mid-2018. An Apple Watch on LTE-M is not likely in 2018, but it is possible.”
While it’s not about costs, there are some differences between the technologies. “There are some differences, LTE-M carries voice, for example,” says Rebbeck. “While NB IoT is cheaper and has a longer battery life. LORA is even cheaper and has an even longer battery life.” He says that this is causing a problem for manufacturers who need to decide what technology to support. “There will be consumer electronics manufacturers who are delaying an investment decision because they want a technology.”
But, he says, this indecision about what technology to support is not redolent of the battle between VHS and Betamax in the consumer electronics space. “They’re both variations of LTE and they’re going to co-exist,” he says.
The report also draws attention to the battle between LTE-M and NB IoT in the connected automotive market, where there’s a competition between cellular vehicle-to-everything (C-V2X) and 802.11p technology.
However, in this instance, this is not so much an issue that’s going to be decided by the providers, this could well depend on some state intervention. As the report points out, “Much attention will be on the European Commission and whether it decides to mandate V2X. A decision either way could have a significant impact on the success of either the LTE-derived C-V2X technology or the 802.11p standard.”
As Rebbeck explains, the EU would have other governments on their side — the US and China governments have already announced their support of 11p.
So, while we wait to see what the market decides on IoT technology, it looks like state intervention could be deciding factor in the connected automotive world. It will certainly be interesting to see which one stimulates the market to the greatest degree.
