NB-IoT application scenarios Does electricity meter reading support NB-IoT?The scenarios of power meter reading are divided into user-side communication and distribution network communication systems. The frequency band of the power load monitoring system adopts 230MHz+1.8GHz TD-LTE private network.

The difference between LoRa and NB-IoT, the technology used by NB-IoT is cellular communication, and the linear spread spectrum used by LoRa. The network deployment of NB-IoT can be multiplexed with existing cellular base stations, while LoRa requires independent network construction.

The industry applications of 4G DTU are mainly in the following major industries:Common application: PLC realizes wireless communication application through DTU, DTU and remote configuration software realize wireless transmission

4G DTU adopts high-performance industrial-grade 8/16/32-bit communication processor and industrial-grade wireless module, uses embedded real-time operating system as software support platform, and provides RS232 and RS485 (or RS422) interfaces, which can be directly connected to serial devices , to realize the function of transparent data transmission.

Wireless technology enables devices to establish network connections and communicate with each other without the need for wired cables. There are currently many different wireless technologies in hardware products in the fields of Internet of Things (IoT) and Machine-to-Machine (M2M) communication. used in. The three common wireless protocols are lora, NB-IOT, and ZigBee. Next, let's take a look a···

ZigBee is a low-power local area network protocol based on the IEEE802.15.4 standard. LoRa is one of the LPWAN communication technologies. So which is better, lora wireless or ZigBee? Today we will take a look at the specific introduction.

Which is better, LoRa or NB-IOT IoT low-power wireless technology?The biggest difference between NB-IOT and LoRa is whether they work in licensed spectrum and so on.

LPWAN (low-power Wide-Area Network, low-power wide-area network) has emerged rapidly in recent years. NB-IoT and LoRa are typical representatives and the two most promising low-power wide-area network communication technologies. So which is better, NB-IOT or LoRa IoT long-distance low-power wireless technology?

The difference between RTU and DTU:RTU = remote terminal unit remote terminal device;DTU==data-transfer unit Data transfer unit;RTU is more complicated than DTU.

RTU is a remote terminal equipment, which is an automatic equipment based on "telecontrol" technology (telemetry, remote signaling, remote adjustment, remote control) installed in power plants and substations in the power grid dispatching automation system. PLC is a programmable logic controller, which performs data aggregation and instruction processing in the field station. It has a variety of c···

RTU is the abbreviation of Remote Terminal Unit (remote measurement and control terminal), which is the basic unit of SCADA system. An RTU can have several, dozens or hundreds of I/O points and can be placed in the field near the measurement point. RTU should have at least the following two functions: data acquisition and processing, data transmission (network communication), of course, many RTUs ···

4G transmission terminal DTU products include 4G DTU, 3G DTU, LTE DTU, TDD DTU, FDD DTU, GPRS DTU, TDD-LTE serial converter, FDD-LTE serial converter, etc.

NB-IoT and LoRa are both representatives of the field of low-power wide area networks. As representatives of the field of low-power wide area networks, both NB-IoT and LoRa are long-distance transmission technologies and are hard to distinguish. Then NB-IoT and LoRa are very strong. Who is the future trend of the Internet of Things? Let's take a look at the specific content.

Data terminal (4G DTU) access: 4G users can choose CMNET and APN to access the network. CMNET is usually used for public users, and APN is for industry users, usually in a group. Users need to set a user name and password, which is more secure good. In addition, APN users can apply for binding fixed IP addresses of mobile intranets.

Smart gateway, also called industrial IoT smart gateway, wireless data collection gateway, communication collection gateway, wireless gateway, industrial communication gateway, wireless sensor management host, industrial Ethernet serial port smart gateway, RS485 serial port Modbus RTU smart gateway, belongs to wireless sensor Internet product.
