Industrial-grade PoE switch is a switch with power supply function. PoE switch is widely used in the field of security monitoring and wireless coverage, which can save the cumbersome power supply wiring for camera and wireless AP. So how far is its POE power supply distance?

DTU has a wide range of applications. In a broad sense, when communicating, the module units responsible for sending data information at both ends of the transmission data link are called DTUs, which convert the format of the transmitted information and organize and verify the data. In a narrow definition, DTU generally refers to the lower GPRS / WIFI / 3G / 4G and other transmitting terminal equi···

Choose a managed or unmanaged switch: If the network is relatively simple, you can choose a plug-and-play unmanaged switch; if it is convenient for future maintenance, you may need to choose a managed switch. Only a managed switch can achieve ring topology connection .

Why choose transparent transmission for 4G DTU data transparent transmission module,Transparent transmission refers to a data transmission method that has nothing to do with the medium of the transmission network, the modulation and demodulation method, the transmission method, and the transmission protocol.

What is CPE? First of all, to understand it literally, it is the abbreviation of "Customer Premise Equipment", which translates to "Customer Terminal Equipment". Because 5G CPE equipment is equivalent to a 5G router.

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···
