The options to be confirmed when choosing a best 4G router

Before you purchase E-Lins 4g router, you must complete the job of information confirmation so that you can choose a suitable 4G DTU.

First, brand and quality choice 

Brand is a symbol of quality and workmanship, and vice versa. The design and craftsmanship also demonstrate the power of the brand. It is hard to believe that it is a qualified product with quality assurance, and you can imagine the failure rate. Some manufacturers offer 4G DTU at very low prices. They just encapsulated the communication module into a 4G DTU, without encapsulating the underlying protocol. Customers also need to use the underlying AT command set to use it, which is very inconvenient.

Second, function selection 

Under the premise of ensuring product quality, the next step is to check whether the functions of 4G DTU meet the application environment of the project. Is it for data transfer, SMS transfer, or both? Some manufacturers' DTUs cannot be used for SMS transmission, and even the packet size of SMS transmission is not sufficient for most projects. In addition, some projects want to use network access in addition to transparent transport capabilities. In this environment, a 4G DTU with a network port is selected, or it can be said that this is a wireless transmission terminal device with both DTU and router functions. At the same time, the E-Lins best 4g router can also be optional support GPS, 5-60V wide voltage, serial port RS232 or RS485, etc.

Third, Select the amount of communication data 

Devices with large and fast communication data will inevitably have an advantage. The 4G DTU provides customers with high-speed Internet access and wireless data connectivity at downlink rates of up to 100Mbps and up to 50Mbps, suitable for large data transmission applications such as serial camera image transmission. The ping value of a 4G DTU is lower than that of a 2G / 3G module, and the time it takes to send a packet from the module to the response from the receiving server is shorter, which is suitable for applications that require high response speeds, such as remote alerts.

Forth, Interface selection 

The choice of interface is mainly to choose the terminal form, such as full duplex RS232 interface or half duplex RS485 interface. The corresponding interface is easy to operate and relatively powerful, which reduces the trouble of bad contact. Of course, the more interfaces you have, the more benefits you get.

Fifth, the choice of frequency band 

Choosing the right support for 4G spectrum is also important, depending on the carrier of the SIM card you are using. Different countries, and even different carriers, support different bands. When purchasing a router, you need to confirm with us the country you are in and the frequency band you need to ensure that the router can works, so as to avoid wasting time and cost during purchase.
