M2M is machine-to-machine communication usually used for remote monitoring, the main purpose is to use sensor data and transmit it to the network. The main components of the system include sensors, RFID, Wi-Fi or cellular communication links, and autonomous computing software programmed to help network devices interpret data and make decisions.

wireless communication technology is very important for IoT products and solutions. With the growth of wireless applications, there will be more and more various technologies and devices, and more and more rely on wireless communication technology. Today we use this article to take stock of the advantages and disadvantages of the main wireless communication technologies in the Internet of Things a···

In the Internet of Things industry, Narrowband Internet of Things (NB-IoT) is an emerging technology that can be widely used worldwide. It has unique advantages. It has wide coverage, multiple connections, low speed, low cost, low power consumption, Excellent architecture features. NB-IOT uses the license frequency band, and can adopt three deployment methods: in-band, guard band, or independent c···

When using edge data centers to move data processing closer to the data source, this number may drop to microseconds. Shortening the physical distance between the data center and the end user can not only minimize latency, but also improve reliability.

Industrial Gateway: A computer system or device that acts as a transformational task. Moving data between two systems that use different communication protocols, data formats or languages, or even completely different architectures, is the most complex network interconnection device. Incorporating edge computing, in addition to the basic protocol conversion function, it also has the following func···

PoE industrial switches refer to industrial switches with PoE power supply, or industrial-grade PoE switches. Industrial PoE switches are based on existing industrial Ethernet switches, embedded with PoE power supply chips, and provide terminal network equipment through network cables. Power and data transmission, realizing PoE power supply scheduling for terminal equipment, and providing more con···

Managed switch or unmanaged switch: If the network structure is simple, you can choose a plug-and-play unmanaged switch; and if you take into account the convenience of subsequent maintenance and other factors, the managed switch is a better choice, because Only managed switches can achieve redundancy.

The industrial Ethernet switch adopts the storage conversion and exchange method, and at the same time improves the Ethernet communication speed, and the built-in intelligent alarm design monitors the network operation status, so that the reliable and stable operation of the Ethernet can be ensured in the harsh and dangerous industrial environment.

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···
