LAN port: Most of today’s 4g WIFI router with sim card slot are designed with 2 or more LAN ports. To use the Internet through a network cable, users can connect the LAN port from the main modem to the terminal devices such as laptops, televisions, computers.

In addition, the LAN port also has many different speeds such as there are 10 types. /100Mbps, 10/100/1000Mbps… can meet high transmission speed

4g WIFI router with sim card slot Antennas:

 There are two types of antennas on the router.  These are external antennas and underground antennas. Most antennas now have external antennas, the more antennas there are, the stronger the WIFI broadcast will be.

In addition, the router also has a power port, signal lights, a few specialized buttons are all external parts. Moreover, The inside of the 4g WIFI router with sim card slot includes:

• RAM,
• CPU
• IC receiver and algorithm

4g WIFI router with sim card slot Working principle

For a WIFI router to fully work for entertainment and WIFI broadcasting, the router is linked to a modem with an Internet connection ion of network manufacturers. You need to distinguish between modem and WIFI router to avoid confusion.

Working principle of a WIFI router

Between the modem device and the WIFI router link through a network cable from the LAN port on the main modem through WAN or LAN ports depending on the policy you use.

In addition, the devices in the network will have a separate IP address, then the router will help route and transmit packets in nature and the Internet environment in the most proper way.

The time the 4g WIFI router with sim card slot transmits documents is very short, without interrupting the transmission or disconnecting when using Internet services.

The main function of the router

Not only that, the WIFI router is responsible for sending packets (packets) between 2 or more networks. It is a WIFI hotspot so that receiving devices such as computers, smartphones, televisions … can completely link through WIFI or LAN to be able to fully connect and use the Internet.

The router’s main feature is to send packets of data back and forth, it can completely divide a network line for many devices connected to it. In other words, on the router, users can completely plug in the LAN connection directly to their computer, or can completely use the WIFI broadcast from the router.

The router wants to broadcast WIFI or transmit Internet documents; it is link to the modem. The modem then can be 1 port, 4 ports, or many ports and must have a WIFI transmitter antenna.

Working principle of the main function of the router

For a WIFI router to work and broadcast WIFI, the router is linked to a modem with an Internet connection of network providers. Also, you need to distinguish between modem and WIFI router to avoid confusion.

Working principle of a WIFI router

Between the modem device and the WIFI router is connected via a network cable from the LAN port on the main modem through the WAN or LAN ports depending on the mode you use. Also, In addition, all devices in the network will have a separate IP address.

And then the router will help route and transmit packets in the Internet environment in the most accurate way.

The time the 4g WIFI router with sim card slot transmits data is very short, without interrupting the transmission or disconnecting when using Internet services.

Not only that, the WIFI router will be responsible for sending packets (packets) between 2 or more network systems together. Also, it is the WIFI hotspot so that receiving devices such as computers, phones, televisions. It can connect via WIFI or LAN to be able to connect and use the Internet.
