LPWAN is a bit like a soup with a smooth surface and a carefully prepared soup. When you stir it gently, you will be surprised to find the hidden treasure! For M2M communications and the Internet of Things, today, the choice of deploying networks is beyond imagination, so that the most suitable solution can't be found. On one platform, not only the networking equipment is growing at a high speed, but also the battery life and low data rate are higher requirements, so LPWAN technology is regarded as the core element to support this demand. However, various innovative technologies in the field of LPWAN have emerged, making competition in this field intensifying. Patent technologies such as Sigfox, LoRa, and Ingenu have developed a good blueprint for building a globally available set of standards based on unlicensed spectrum in the public sector. However, in the process, the popularity of these technologies is also facing huge obstacles. The challenge from the cellular IoT technology has made this already fierce competition even more difficult. Not only that, Machina Research's chief analyst even said that there will be more competitive technologies to join the competition in the future. Weightless-N, Weightless-P, NB-Fi (WAVIoT), Accellus, Flexnet (Sensus), Telenasa UNB and Synergize (Aclara) are all worthy of attention, although this is only a small part of the LPWAN field. In addition to these, you can discover the shadow of other technologies on a large number of critical applications. David Hammarwall, leader of the radio business unit of Ericsson Sweden, summarized the current situation: EC-GSM, NB-IoT and LTE-M1 are the main LPWAN technology competitors in the cellular field, and the future of these technologies depends on the operator's application. Case and network evolution strategy. Patented technology vs standard technology In the future, how many standards can these standards rise? In the dispute between patented technology and standard technology, is it necessary to stage a "you die" story? Or is it a large number of different technologies that can coexist continuously? Nokia marketing leader Arne Schaelicke explains why standards such as NB-IoT are so interesting: "Since Sigfox, LoRa and Ingenu are based on unlicensed spectrum, access thresholds are lower, and more competitive technologies will emerge in the future. It is clear that the increasing number of technologies and access devices in this band will maximize the risk of interference, and that cellular IoT technology based on licensed spectrum can provide reliable connectivity in terms of providing large-area and long-term connectivity. IoT connectivity.†Steve Hilton agrees that he believes that operators seem to have the idea of ​​building a standard base network. After all, building a long-term market, the cellular Internet of Things can minimize the risk, and this is precisely A crucial factor. Undoubtedly, NB-IoT has caused a huge sensation between traditional mobile providers and communication operators. Although the standard has not yet been introduced, 3GPP is working on this and hopes to freeze and release the NB-IoT, a narrowband Internet of Things technology standard based on cellular networks, in June this year. Although not all technologies can survive for a long time, this does not mean that standard technology and cellular technology cannot coexist. Perhaps the best explanation is that operators are claiming support for NB-IoT/LTE Cat-M2, but they are also investing in other technologies outside the cellular network. Which technology is more popular? It depends on the technology itself and the business factors Steve Hilton Hilton, founder and general manager of MachNaTIon Research, points out that if the 3GPP solution takes a long time to implement, then these patented technologies will have an opportunity to develop and re-engineer and customer. And if the 3GPP solution is implemented quickly, these patented technologies will slowly lose the prospects that are now foreseen, and eventually LPWAN technology will become a small part of this huge connection blueprint. From a business perspective, we need to understand the differences between all the different LPWAN technology models. Sigfox and Ingenu are committed to building networks, while LoRa is more inclined to create the entire ecosystem, which means that every technology will be different. Application case. From a technical perspective, Ingenu's RPMA is indeed more suitable for providing stable IoT services. However, things have two sides. For example, not all IoT sensors need to have downlink capability in different application cases. In addition, Hilton also said that the most important factors affecting corporate decision-making are the Internet of Things application access platform, platform solutions, technology integration, and IoT network security. So, for some companies, which IoT solution is more challenging than choosing which LPWAN technology to use.
