Author: Zhao Xiaofei IoT Think Tank Original Please indicate the source and origin when reprinting Introduction In scenarios requiring public networks, NB-IoT and LoRa have strong complementary characteristics. However, in projects that require industry or enterprise-level private networks, NB-IoT private network solutions have a clear substitute relationship with other technologies such as LoRa, Weightless, and … Read more
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
This is an interesting and special 5G plan. The plan is as follows: Phase One (November 2018 to March 2020) First, through shared towers and satellite backhaul, quickly establish a nationwide coverage 700MHz NB-IoT network. Phase Two (March 2020 onwards) Transition from NB-IoT to 5G, supporting all 5G applications except mobile broadband services, specifically providing … Read more
