There are several types of LPWAN networking technologies emerging, each with competing networking protocols that make the IoT World of IoT more complex ...

The number of networked devices has skyrocketed as a result of network technologies built specifically for Internet of Things (IoT) applications, the so-called low-power wide area network (LPWAN). As the name implies, LPWAN is a technology that demands very little power consumption, small data transmission and low bandwidth. They can connect several private and public IoT devices to serve a wide range of users and promote the development of smart cities.

There are several types of LPWAN networking technologies that are emerging, each with competing networking protocols that complicate the IoT world; this is no longer a matter of IoT device usage scenarios, but rather end-user and numerous Compatibility of emerging protocols. Worse, smart cities may evolve into more than one dedicated, isolated network.

In light of recent industry news, several competing companies such as Sigfox are planning to deploy their networking technology in a number of U.S. cities, including New York and Los Angeles, by the end of 2016. These issues are particularly relevant.

LPWAN technology because of the limited transmission range, making the type of network construction investment required for the relatively small size, and almost no maintenance. Sigfox, a major technology supplier, has a clear competition with many of the industry's alliances with many companies that support other IoT protocols; for example, Cisco and Huawei are using LoRa and NB-IoT protocols Get a lot of attention on the market.

According to research firm IDC, the U.S. investment in IoT-related products and services will reach 232 billion U.S. dollars by the end of 2016, and the growth rate in the following three years will exceed that of the U.S. market. 16%. The participants in the market, from product engineers to government authorities, wondered which of the communication protocols was the last to win.

The reality is that the LPWAN market is still in its infancy, so it is too early to answer these questions; judging from some early indications, it seems that there will not be only one protocol in the IoT area for IoT.

Imagine the mobile operating system is still ongoing war, no one in the past optimistic about Apple (iOS) iOS will become so welcome now, after all, it is an independent, incompatible system; but the iPhone almost overnight become ubiquitous , And form a complete market around the device. But the topic of Android phones is still ongoing, these products currently account for the entire smart phone market, more than Bacheng.

The same holds true for the IoT market, which has plenty of room for multiple competing protocols, and various devices that blend in with different protocols.

It is important to understand that there is more than one device that uses LPWAN technology; those networks can be integrated into a wide range of applications such as utilities, healthcare, security, and many other end devices and systems, from the simplest of environmental sensors, Intelligent controls to mirrored systems.

Those networks need to be viewed as models of current mobile networks, and they should periodically perform performance assessments to ensure their integrity and therefore optimize cell services on the network; those services include energy management, urban mobility ), Or waste monitoring.

However, IoT networks, whether stacked over traditional carriers' mobile networks or independently, can not be censored as they are today's cellular networks; mobile companies often closely observe the movement of a mobile The successful completion of the data tasks initiated by the device and the speed at which such tasks are performed. .

The IoT network is primarily machine-to-machine communication that facilitates the transfer of light-weight data and does not necessarily require cellular-class throughput; what's more important for such networks is ensuring that they have enough robustness to do all their tasks, as well as networks Waiting time is an acceptable range for IoT applications using this network.

Even more important in IoT is that data can be reliably transmitted when needed, not necessarily how fast; consumers complain that the download takes too long, but those sensors do not. But of course, the data is still delivered within the required timeframe.

The development and widespread deployment of LPWAN has opened the door to a new world of technology used by the public in everyday life; however, the investment and implementation of the IoT program by government agencies to allow field trials to become public services will still be self-propelled by the IoT industry The direct impact of the speed of order. Sigfox has taken the lead in striding, recently announced the launch of the IoT module costs only 2 US dollars, other manufacturers will be how to respond? And let's wait and see!
