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.

Zokolink is a M2M wireless communication backbone enterprise, mainly providing: industrial wireless routers, wireless data transmission terminals, 4G routers, ZigBee terminals, LoRa/LoRaWAN gateways, etc.

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.

5G industrial routers are industrial grade (lower than industrial grade is consumer grade, higher than industrial grade is military grade). Second, it is a high-performance router. Third, the WLAN port of this router is a wireless port, which adopts the LTE standard (TDD or FDD), so it is called a 5G industrial router.

4G router is an industrial IoT high-speed router, compatible with 4G/3.5G/3G/2.5G network, flagship-level configuration, VPN link, industrial-grade protection, wide temperature design, can easily build high-speed and stable wireless transmission network , using the public LTE network to provide users with wireless long-distance data transmission.

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.

First of all, many people do not have a clear understanding of the concept of the transmission range of industrial-grade wireless routers. Generally, the wireless network signals of industrial wireless routers are marked in the manual. Usually, the effective transmission distance ranges from 100-250 meters, so many people think that As long as it is within this transmission range, the signal can b···

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···

Industrial 4G routers provide services such as parking space query, reservation, and entry and exit information records in smart parking lots. Vehicles enter the parking lot by means of license plate or vehicle identification, and lock or guide the parking space through the industrial 4G router, so as to achieve the purpose of convenient, fast and safe entry and exit of parking users.
