The Ministry of Industry and Information Technology has issued a notice to promote the deployment of 1.5 million NB-IoT base stations. NB-IoT is surging forward. Many netizens have requested a comprehensive article on NB-IoT, so here comes a super detailed technical article. 1 NB-IoT’s Journey From 2G to 4G, mobile communication networks have been continuously … Read more
Typically, we categorize IoT devices into three types: ① No mobility, large data volume (uplink), requiring a wide frequency band, such as urban surveillance cameras. ② High mobility, requiring frequent switching, small data volume, such as fleet tracking management. ③ No mobility, small data volume, not sensitive to latency, such as smart metering. NB-IoT was … Read more
A new protocol support has been added to the IoT access — CoAP (Constrained Application Protocol)! What is IoT access? It is a fully managed cloud service developed by Baidu Smart Cloud’s Tiangong team, which helps the Internet of Things establish secure and reliable bidirectional connections and device management between devices and the cloud. It … Read more
This article introduces the CoAP protocol in the ThingsBoard platform, primarily due to the increasing application of NB-IoT in the IoT field. First, let’s briefly understand that the CoAP protocol (Constrained Application Protocol) is designed by the IETF specifically for constrained application environments. Functionally, it is similar to HTTP, but compared to HTTP, it is … Read more
Author: Hussain Fakhruddin Translated by: Mu Yunfei The recent surge in the global Low Power Wide Area Network (LPWAN) market can be attributed to several factors. The rapid development of machine learning and M2M communication standards has played a significant role, coupled with the growing global demand for IoT services, the availability of low-cost LPWAN … Read more
Today, I want to talk about LoRa. In the past six months, I have repeatedly mentioned “Internet of Things“. When discussing the Internet of Things, the term I have used the most is “NB-IoT“. [Reference Reading] Previous articles about NB-IoT: I’ve heard that this NB thing is going to take over… What can NB-IoT actually … Read more
1. Introduction IoT applications need to consider many factors, such as node cost, network cost, battery life, data transmission rate (throughput), latency, mobility, network coverage, and deployment type. It can be said that no single technology can meet all the needs of IoT. The two technologies, NB-IoT and LoRa, have different technical and commercial characteristics, … Read more
