As we all know, although LTE and NB-IoT are closely related, the design goal of LTE is high speed and large data volume, while NB-IoT is designed for the “intermittent transmission of small data” for the Internet of Things (IoT), making their directions opposite. Therefore, the LTE core network (EPS) is no longer suitable for … Read more
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
This is the 5G networking option we are all familiar with… There are options 2, 3, 4, 5, and 7, but there is no option 6. So what does option 6 look like? It connects the 4G core network to 5G base stations, and only connects to 5G base stations. This option was proposed around … Read more
