What is LPWAN?

Application Areas

While LPWA networks offer many possibilities, some use cases are easier to define than others because they have already been tested and implemented in real-life scenarios. Of course, this does not prevent innovation. In fact, new and experimental use cases are the driving force behind the IoT, and LPWAN is perfect for this. lpwa standardHowever, in the early stages of its development, there are still many discoveries to be made about the possibilities of implementing low-power WANs.

Parking Management

While parking resource management poses a greater challenge in growing urban areas, LPWAN offers a flexible and effective solution to this problem. Starting with the IoT technology sensors that allow students us to identify whether a parking space is occupied or not, this information can be used as input to many enterprise applications, such as signs indicating how much space is available at a given level or indicating where these service stations are located, or even simultaneously informing authorities through a data interface that certain social vehicles have been parked for too long. For learning this situation-specific use, the low-power characteristics of LPWA networks are more obviously important than the remote control characteristics studied. After all, it is never cost effective to replace the batteries of hundreds (or even thousands) of parking space monitors every month.

Public Lighting

Whether on a sidewalk, a crowded intersection or an isolated highway, thousands of light bulbs are lit everywhere. In most cases, monitoring such networks means that someone sees the lights go out and calls the appropriate authorities. However, with LPWAN, the lights themselves can alert the command center if they are being operated and if they are turned on or off, allowing for better use of energy and improved safety.

Water Pressure Test

A simple pressure gauge can transmit data readings in a timely manner and can even help detect leaks before they are detected or any damage occurs. The ability to communicate over long distances without a network is critical for pipeline networks up to several kilometers long, and the expected battery life should be measured in years. In cities, signals that provide long-range communication in rural areas can also be used for underground infiltration so that underground pipes can be monitored.

Smart Pallets

In order to track goods, you usually need to always scan the load as it is loaded to another person or place. In between these transfers, it can simply be assumed that the goods remain in the same building or on the same truck or train when they move. The advent of LPWA, however, makes it possible to implement smart pallets that not only continuously send signals, but also track the location of the goods and whether they have been opened, discarded or mishandled. Here, LPWA can be used not only for long-distance communication when goods are moved from one location to another, but can also benefit from battery life, as no one wants to find and replace the batteries of a frequently moving pallet.

Types of LPWAN Technology

Non-Cellular LPWA Networks

Over the past decade, two major types of LPWAN technologies have emerged: networks based on non-cellular problem solving Chinese solutions, such as Sigfox or LoRa, and networks where enterprises use companies' existing research cellular data technologies to develop the provision of information services, such as LTE-M and NB-IoT.

Standardized Cellular LPWA Networks

While Lora and Sigfox technologies are becoming increasingly important in today's iot connectivity space, it is no wonder that mobile network operators are trying to get their iot cake and eat it too by deploying lpwan for iots using cellular solutions.

3GPP, dedicated to mobile technology standardization, has proposed two IoT standards based on existing cellular networks:LTE-M and NB-IoT to alleviate compatibility issues and reduce production costs for M2M applications. Communication modules. LTE-M offers more consistent speeds, shorter latency and better roaming than its non-cellular competitors due to the use of licensed spectrum and the same protocols as 4G.

Conclusion

While there already seems to be some intense competition in the LPWAN standards business relationship in the IoT space, the duel is actually a win-win. Why is this the case in China? First, because they each focus on meeting the needs of different use cases, and given the huge diversity of applications for IoT systems, we teachers can safely assume that all LPWAN technology issues will find a niche market that requires a country to grow. Secondly, the rapid economic development and the growth they are working are learning to experience mainly because still considered not yet the most advanced technology can only make the prospects of LPWAN technology research how much better. The more they are discussed, promoted and deployed, the more likely it will be that the ultimate goal of their growth will be achieved through the emergence of an all-inclusive standard that establishes a way to unify their benefits in a single student solution.
