Market analysis, development situation and trend comparison of NB-IoT and LoRa

Which market development situation is better, NB-IoT or LoRa technology? Which one is more promising?

Here is a brief description of their development trends

NB-IoT and LoRa

1. Power consumption

Since the two IoT technologies of NB-IoT and LoRa are both low power consumption, the current consumption (peak current and average current) of the node can be more detailed.

The synchronization protocol of the cellular network must also be used, and the terminal must be regularly connected to the Internet and have a short downlink delay.

LoRaWAN uses the asynchronous ALOHA protocol, which needs to wake up the terminal regularly;

Just like a lazy man, if others (terminals) don't ask him to get up and do something, he goes to sleep and wakes up when something happens, but he falls asleep after doing something.

The terminal can provide corresponding solutions and measures according to the specific application to achieve the required scenarios.

2. Battery life

The use of a cellular network must sacrifice node and battery life, but the use of a cellular network can increase the utilization rate of the spectrum.

LoRaWAN nodes will have deficiencies in spectrum utilization, but in order to extend battery life and reduce costs, we have to weigh the pros and cons.

3. Spectrum authorization

It is difficult to distinguish between NB-IoT and LoRa which has more advantages in technology development. It is just that NB-IoT has inherent characteristics and conditions, which makes NB-IoT have certain advantages in the early stage of development, but the conditions of LoRa are not bad. It's just relatively "low-key";

The most obvious difference between NB-IoT and LoRa may lie in whether the work can authorize spectrum. NB-IoT can be allowed to authorize spectrum, but LoRa is not allowed to authorize spectrum;

Compared with NB-IoT, LoRa does have shortcomings in the protocol;

It also leads to NB-IoT that can be directly connected to the cellular network background, while LoRa can only connect to the application server through an indirect connection method. If the background application server is shut down, the information data transmission will be affected, which is extremely inconvenient.

In practical applications, because unlicensed spectrum products will have unstable conditions and specific problems, the blocking and development of licensed and unlicensed spectrum will also affect the development space of NB-IoT and LoRa technology.

4. Field foundation

The advantage of NB-IoT is that it can use the stable base station foundation of the three major operators, and can make full use of the base station for data transmission and collection;

And LoRa can also rely on the enterprise-level LPWAN field to transmit information and data.

Therefore, NB-IoT and LoRa technology have a parallel and good competitive and cooperative relationship, and represent different authorized spectrums. They start from different advantages and can assist each other in common development. They bring new vitality to the Internet of Things era. , To promote the progress and glory of the Internet of Things era.
