Many projects use 4G transmission because they can't use broadband, so how to choose a 4G Industrial Router ? There is a people association to interpret for you.
It is a multi-network port 4G Industrial Router with four network ports. It supports all Netcom, and can be connected to switches, PLC, cameras, touch screens, etc. It has strong expansibility and supports secondary development. It can realize PLC remote control, PLC remote debugging and PLC remote download.
● Stability of 1.4G Industrial Router. The stability of the equipment is very important because it is used in the unattended situation, which is related to the stability of the whole network data and the realization of the function. The device needs to support software restart and hardware watchdog to ensure that it runs for a long time without problems.
● Scalability of the 2.4G Industrial Router. Some 4G Industrial Routers have only two network ports, and some do not support serial ports, so the compatibility of subsequent projects should be taken into account when purchasing.For example, for PLC remote monitoring, in addition to the interface of PLC itself, touch screen and video monitoring may also be used, so it is better to choose 4G Industrial Router with multiple network ports and serial ports.
● Price of 3.4G Industrial Router. Because of cost considerations, price is an important factor for many users to consider. The price is too high, beyond the cost budget, users can not accept. Is the lower the price, the better? Not really.The unusually low price means that the product may not use industrial modules, which may affect the stability, not because the initial purchase cost is low, but the later maintenance cost is high, the loss outweighs the gain. Therefore, a reasonably priced 4G Industrial Router is important.
● Technical support. Unlike ordinary routers, 4G Industrial Router will use VPN function, port mapping and other network technologies in many projects. If you are not familiar with the network, you may encounter problems in the use process. Therefore, it is very important for a company to provide timely technical support and respond quickly to customers.
● 4G Industrial Router chip. 4G Industrial Router supports the use environment from -20 ° to 75 °, so it is necessary to consider the project implementation environment.
● 4G band. 4G Industrial Router supports 4G/3G/2G of China Telecom, China Mobile and China Unicom, eliminating the trouble of changing cards.
