Advantages and disadvantages of zigbee protocol and main application areas of zigbee，Mainly used for short-range wireless connections. It has its own protocol standard that coordinates communication among thousands of tiny sensors.

The difference between 4G LTE gateway and CPE,4G CPE is an LTE data terminal device that converts high-speed 4G signals into WiFi signals, which can support a large number of mobile terminal access. 4G CPE can be widely used in wireless network access in rural areas, towns, hospitals, units, factories, communities, etc., which can save the cost of laying wired networks.

As the most promising low-power wide-area communication technology, LoRa has been used in all walks of life. LoRa uses linear frequency modulation spread spectrum modulation technology, which maintains low power consumption, significantly increases communication distance and network efficiency, and eliminates interference, so that even if the same frequency is used for simultaneous transmission, t···

NB-IoT application scenarios: Agricultural Internet of Things, intelligent manufacturing, trash cans Does the Agricultural Internet of Things support NB-IoT?The agricultural Internet of Things usually adopts M2M, Zigbee, 433MHz, WiFi, wired, etc. The main problems focus on network coverage, power supply and cost.

NB-IoT technology can solve the problem of low power consumption, but it needs to be established when network coverage is in place and global roaming access is available.

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.
