At present, the most popular LPWAN technologies are LoRa, Sigfox, and NB-IoT. These three technologies have their own advantages. The public can select the most suitable communication technology according to different fields and usage requirements. What are the specific differences between NB-IoT, LoRa, and Sigfox? Is there any detailed comparison information?
What is the difference between NB-IoT, LoRa, and Sigfox?

Wireless communication technology is the transmission basis of the Internet of Things. With the development of smart city applications becoming popular, various technologies have been introduced and new, and they have seized the Internet of Things market. Among the LPWAN technologies, the most popular ones are LoRa, Sigfox, and NB-IoT.

In the trend of the Internet of Things, what are the advantages of each of these three technologies? Who will be the best partner in your professional field? The words of the Internet of Things, big data, AI artificial intelligence, the relevant industry personnel must be familiar with the heart.

In the technical framework of the Internet of Things, “sensing” is the most basic core source. In the fields of agriculture, industry, construction, transportation, medical care, etc., the sensed data should be analyzed through AI to form related applications. First, you must deploy the appropriate transmission technology and domain to collect and report huge amounts of environmental data. In wireless communication technology, WI-FI, Bluetooth, ZigBee, and Z-Wave, which have been launched earlier, have laid the foundation for development in different fields. WI-FI is suitable for large data transmissions, such as audio and video transmission or AR/VR. It is also the basis of general wireless network. The disadvantage is that it consumes a lot of power. Bluetooth is mostly used in personal wearable devices. Mature; ZigBee and Z-Wave are fruitful in automatic control applications such as industrial and construction.

When it comes to wireless networks, what everyone thinks of, besides WI-FI, it is probably the mobile communication network of mobile phones. Today's communication technology is about to enter 5G, which is about higher bandwidth, higher speed, lower latency, and of course more power consumption. Because it is communication between people, data transmission is more intensive and the amount of exchange is more. huge. For M2M communication, because the deployment scope of the device is generally wider, and the wireless device must avoid frequent battery replacement, LPWAN (Low Power Wide Area Network) technology takes advantage of the situation, its small data volume, long-distance transmission and The power-saving features make a big splash in the field of Internet of Things applications.
