Mobile Communication Networks Have Made Many Users Consider ADSL Internet As A Backup Solution And Go For Mobile Internet. 

Internet, which in ideal conditions has a faster speed than fixed ADSL Internet. To use mobile Internet the best way, you should consider getting an excellent portable modem.

SIM card modems are divided into three main groups.

• The first group is modems with built-in batteries that allow you to use them on the go, similar to how you turn on the Internet on a smartphone.
• The second group is home modems, similar to fixed modems placed in a place and must be connected to a power outlet.
• The third group isis dongle modems connected to the computer through a USB port.

Mobile modem

The mobile modem is one of the most popular options nowadays, which serves users for a long time because it is equipped with an internal battery and does not have a color screen. The function of mobile modems is similar to that of smartphones, except that there is no more premature battery drain, and when the client devices are turned on, you must connect to them via Wi-Fi. One of the disadvantages of mobile modems is limited support for the number of connected devices.

In general, these modems support up to 10 clients simultaneously. The presence of a small screen that provides essential information to the user is one of the main advantages of mobile modems. Of course, buying modems means that another device needs to be charged.

Today’s mobile modems from 4G networks are supported and are mostly energy-efficient, as their screen provides only the information needed. On the other hand, desktop modems have more size and weight than mobile modems and are equipped with external antennas. These modems support LAN, WAN, and USB ports and use city electricity without needing batteries.

Required speed

The speed supported by the mobile modem is essential, although 4G modems support 150 Mbps and 4.5G modems support 300 Mbps; before buying high-speed modems, first, check the speed provided by the mobile operator. It helps ensure you don’t waste money on a modem you’ll never get access to at its original rate.

Dual-band or single-band Wi-Fi

The number of antennas is another crucial factor in connection with the modem. Some mobile modems only support the 802.11n standard on the 2.4 GHz frequency and offer speeds of only 300 Mbps. More powerful modems support the 802.11ac standard and allow connection to Wi-Fi on the 5 GHz band. In general, these modems provide a speed equal to 867 Mbps, which may reach several gigabits; of course, this is done thanks to the 2×2 MIMO technology.

Battery, the key player of mobile modems

Today, most modems in the market are equipped with 2500 to 3000 mAh batteries, although the economic models are fitted with 1800 to 2500 mAh batteries. Modems equipped with a 3000 mAh battery can serve the user for 8 to 12 hours. Of course, more expensive modems that use resources optimally can provide service for at least 12 hours.

Additional features of the modem

Support for command codes and the panel for sending and receiving short messages are essential functions many users need. Still, not all modems are equipped with such a function, and only a tiny screen that shows information such as network status and download and upload speed; they show the amount of exchanged data and the amount of battery charge. Guest network definition, monitoring controls, firewall, virtual private network setting, WPS key, memory card support, etc., are additional features of mobile modems.

last word

The modem is a device whose primary function is data modeling. More precisely, it converts analog data into digital data and vice versa. For this reason, a modem is needed to establish an Internet connection based on Dial, one connected to the computer and the other to the telephone line. For this reason, the modem is described as a connector between the digital and analog worlds. A router is a device responsible for routing internet data in the network. In simple words, a router is equipped with ports to each of which a local network is connected.

Modems are generally placed in users’ homes, and routers are placed in communication centers. Still, it is possible to combine modems and routers and provide the user with a single device. For this reason, today, all the ADSL modems you get from the market are no longer straightforward, and in addition to modem and router functions, they also have switch capabilities.

A standard modem is only equipped with two ports that receive analog data from phone lines and send it to the computer on the output port, but modem routers have a different function. Behind a modem router, you see a small DSL port along with several LAN ports and Wi-Fi antennas.

In fact, in the first step, your device is a switch to which devices such as computers and laptops are connected through LAN and Wi-Fi ports, and then these connections are known as a local network with an IP address range.

The other port of the router, which is called the output port, actually plays the role of the modem‘s digital port.

On the other hand, the DSL connection of the modem to which the telephone wire is connected is the analog bus we mentioned at the beginning of the article. With this description, you have a combination of a home switch, router, and modem. As said, the most expensive does not mean the best.

For example, maybe buying a modem4.5G costs a few million because they support 300 Mbps download speed, but in practice, you will never achieve such a speed. Generally, it is better to go for regular 4G modems with a reasonable price range.
