Comparison of NB-IOT and LoRa IoT low-power wireless technologies
LPWAN (low-power Wide-Area Network, low-power wide-area network) has emerged rapidly in recent years. NB-IoT and LoRa are typical representatives and the two most promising low-power wide-area network communication technologies. So which is better, NB-IOT or LoRa IoT long-distance low-power wireless technology?
LPwan
NB-IoT technology has four major advantages:
First, the coverage is wide. The coverage of NB-IoT is 20 db better than that of the traditional GSM network. If calculated according to the coverage, a base station can provide 10 times the coverage;
Second, it can support massive connections. At 200KHz frequency, a base station can provide 100,000 connections with the help of NB-IoT;
The third is low power consumption, the NB-IoT communication module battery can work independently for ten years without charging;
The fourth is low cost. The cost of NB-IoT modules is less than $5.

The main technical features of LoRa:
It is capable of long-distance transmission of 1-20km. In the city, the wireless distance range is 1~2 kilometers. In the suburbs or open areas, the wireless distance can reach up to 20km. The number of nodes can reach tens of thousands or even millions, and how many nodes or terminal devices can be connected to a gateway. The data rate range is 0.3~50kbps, and the lower data rate can make the battery life reach 3-10 years.
Therefore, it is difficult to say which technology has an absolute advantage if it is compared in terms of technology.
