What is the shape of gateway in IoT system?

IoT gateway definition: In the Internet, the gateway is a kind of intermediate device that connects cat 16 speed the intranet and extranet with other networks on the Internet, also called "wireless router", and in the institutional framework of IoT technology, in the perception layer and network layer 2 different networks must be an intermediate device, that is "IoT gateway".

The gateway plays a very important main role in the IoT system, what are the shapes of the gateway?

Wireless network to wireless: WiFi to 433MHz, infrared, ZigBee (common at home)

Wired to wireless network: Ethernet interface to 433MHz, infrared, ZigBee (common at home)

GPRS (2G, 3G, 4G, 5G) to 433MHz, infrared, ZigBee (common in industrial production)

Wireless network to wired: WiFi to RS485, RS232, CAN (industrial production is the majority)

Wired to wired: Ethernet interface to RS485, RS232, CAN (industrial production is the majority)

IoT gateway efficacy is a variety of connection methods fusion down, both to consider the communication requirements of short routes in some areas, but also to complete the connection with the public sex network, and at the same time also need to carry out the solution, sharing and manipulation of data files. The IoT gateway should have the following roles.

Universal acceptability.

The first IoT gateway in the rising communication layer, should have the basic elements of the general Internet technology wireless router, according to the wired wireless network a variety of interface way to connect 4G mobile network, Internet technology, to facilitate the flexible compatible Internet technology. The second IoT gateway has universal perception network acceptance ability, with a variety of fields jack, to ensure the smooth, rapid and accurate acceptance of different kinds of perception data information.

Manageable method capability.

Strong management method capability for all medium and large networks are indispensable. The first to carry out management methods on the gateway, such as application registration management methods, management rights, situation control, etc.. The next gateway to complete the management method of the connection point within the subnet mask, such as obtaining the logo, situation, characteristics of the connection point, and its remote control to complete the evocation, manipulation, diagnosis, update and protection. Because the standard specification of subnet mask is different, the plurality of protocols is different, so the gateway has different manageability capability.

Protocol transformation capabilities.

Transformation of protocols from different sensing networks to connected networks, unified encapsulation of data information in the underlying specification file format, ensuring that the protocols of different sensing networks can be changed into unified information and messages; analysis of data sent from the top layer into messages and program control that can be distinguished by the protocols of the sensing layer.

What exactly does cat M1 mean?

The LTE family of cellular technologies includes CAT-M1 as a type of device; occasionally, this is referred to as "LTE-M," which is the same thing as CAT-M1. Varied categories have different data rates, frequency spectrums, power requirements, and signal ranges, as was discussed in the LTE section.

A cat 16 is what?

A 70-year-old person is the same age as a 12-year-old cat. An 80-year-old person is the same age as a 14-year-old cat. An 84-year-old person is the same age as a cat that is 16 years old.

Are VoLTE and LTE similar?

VoLTE is a more streamlined and enhanced form of 4G LTE. The drawback of 4G LTE is that there is no 2G or 3G network to fall back to, so you won't be able to make calls when you're traveling to remote locations.

Why isn't 5G any quicker?

Technically. How come certain 5G connections are so sluggish? The first and most important factor is the use of low-band carrier frequencies by the far-reaching 5G signals that have driven the bulk of carrier rollouts in the US, particularly those from AT&T and, to a lesser extent, T-Mobile.

Is LTE or 5G more powerful?

In short, 5G can give stronger and quicker connections, larger traffic capacity, and latency as low as 1ms since it uses a different frequency than 4G LTE.
