NB-IoT will of course not be completely replaced by Cat.1. First, in the market distribution of cellular connections, high-speed connections account for 10%, medium-speed connections account for 30%, and low-speed narrowband connections account for 60%. In other words, NB-IoT's current market share of 60% far exceeds Cat.1.

A typical LoRaWAN network architecture includes four parts: terminal, base station, NS (network server), and application server. A star network topology is adopted between the base station and the terminal. Due to the long-distance characteristics of LoRa, single-hop transmission can be used between them. The base station forwards the LoRaWAN protocol data between the NS and the terminal, and carr···

NB IoT stands for Narrowband Internet of Things; Cat-M1, also known as LTE-M, is specifically designed for IoT. But you may not have heard of the third option, but it is most suitable for today's global IoT deployment: the LTE standard called Category 1 (Cat-1).

DTU is a wireless terminal device specially used to convert serial port data into IP data or convert IP data into serial port data for transmission through a wireless communication network.

5G smart gateway can integrate the information collected by different things and transmit it to the next level, so that information can be transmitted between each part. 5G smart gateways can realize protocol conversion between perception networks and communication networks, as well as different types of perception networks, and can realize wide-area interconnection as well as local-area interconn···
