About the Speed

Due to the many inconsistencies between real-world and laboratory conditions, it can lead to 5G speeds not being able to maintain a stable 100Mbps as desired. There are several factors to consider:

  • Base Station Distance: The closer you are to a 5G base station, the better the signal and the faster the speed.
  • Base Station Load: Faster speeds are typically experienced when fewer people are using the same base station. Speeds may slow down during peak hours, such as rush hour.
  • Number of Base Stations: Due to the characteristics of the 5G spectrum, it often requires twice as many 5G base stations to cover the same area as 4G, which can affect coverage.
  • Carrier Restrictions: It's important to confirm whether your 5G card has been limited by your carrier. You can periodically request your carrier to reset your network.
  • Indoor vs. Outdoor Differences: Indoor and outdoor environments can significantly impact signal strength. Building penetration loss and indoor signal reflection can affect speeds indoors.

PS: The current number of base stations may not provide consistent coverage, and speed tests may vary in different locations.


  • Insert the SIM card into the SIM-2 card slot (SIM-1 card slot corresponds to the 4G module) -> Install antenna -> Connect the computer and router with a network cable -> Open the browser and input -> Log in interface -> The initial username and password both are "admin".

Dynamic Domain Name Server (DDNS)

DDNS is to map the user's dynamic IP address to a fixed domain name resolution service. Every time the user connects to the network, the Client program will transfer the dynamic IP address of the host through information transmission. It is transmitted to the server program located on the host of the service provider, and the Server program is responsible for providing DNS services and implementing dynamic domain name resolution.
For example, to map the login IP of the 5G router— to the domain name of Oray, we can also log in to the router through the computer outside the LAN through the domain name:

  • Register Oray -> download client (or Oray console) -> intranet penetration -> apply for HTTP domain name -> fill in intranet host IP (router login IP) and port number (80).

  • Application -> DDNS->Status on -> Select service provider (here select Oray) -> Fill in the mapped domain name, login account, and password of Oray -> click Apply.

SIM8200EA-5G-router-extension-application (1).png

  • Internet-connected browsers worldwide -> enter the domain name mapped by Oray -> log in to the router (the effect is equivalent to logging in to in the local area network).



File Sharing

  • Application -> File Sharing -> FTP Server -> Status Enabled -> Login Method Select username and password to log in -> Enable writable:


  • When the computer is connected to the 5G router -> open the file manager file or browser -> enter -> enter the router shared file directory.

Serial (232)

  • Application -> Serial#(232) -> Open Status -> Select data transparent forwarding mode -> Configure baud rate 115200 -> Data center address (set to here, you can build your own TCP server).


  • Application -> Serial#(232) keep-alive packets are sent to the server regularly -> the content is aa(hex) -> the time interval is set to 2 seconds here.


  • Connect the RS232 interface of USB to RS232/485/TTL to the RS232 interface of the router (TXD-RXD, RXD-TXD) -> upload the data sent by the serial port to the server -> send the data from the server to the serial port.

Note: The RS232 serial port is used as an example here, and the same is true for the RS485 serial port test.



  • System -> Device -> Modify -> Modify the Device Name yourself;
  • Copy from computer -> get time from computer and synchronize with computer time;

Development Software


  • Make sure the router has been turned on and enter the corresponding IP (if you have not changed the IP, the default is 192.1686.8.1).
  • If you have forgotten the IP address, please press the RESET button for about 30 seconds, after all the indicators light up, restore the factory settings, wait for the router to reboot, and then log in with the default IP address.

First of all, it is important to learn the difference between the lab data and actual data, in practice, due to the lack of base stations, signal coverage is not good, 5G coverage holes are also more, and the network speed may not necessarily reach the peak. Under normal circumstances, 4G upload speed stabilized at 20-40Mbps, and 5G upload speed stabilized at 100Mbps (the fewer people, closer to the base station the faster the speed).
