The signal quality of the operator is almost the same for both the mobile phone and the USB modem. If your apartment does not “catch” a cell phone, then the Internet via a usb modem will work just as badly. Various external antennas and amplifiers are used to amplify the signal.
Instructions
Step 1
Please read the instructions for your USB modem carefully. The instructions should indicate whether the modem has an input for connecting an external antenna, where it is located on the case and what this jack is called. If there is no instruction, go to the official website of the operator and view the instructions on the website. Be sure to check your modem models.
Step 2
Examine the case of the modem and find the input for connecting an external antenna. If you are using a homemade antenna, you need to attach the connector to its cable according to the modem's specification. You can find similar connectors at radio parts stores. At the moment, there are a large number of sites on the Internet that sell similar goods. View your modem antenna options and order by mail.
Step 3
If the modem does not have a special input for connecting an additional antenna, you can open the modem case and solder the cable from the cable directly to the modem board. However, in this case, you will probably lose the warranty for the modem, since you will violate the integrity of the case and make changes to the device circuit.
Step 4
The easiest way to attach an external antenna is to simply wrap the end of the antenna cable around the body of the USB modem. This type of connection will not void your device warranty, will not cause a risk of modem failure, but will significantly improve the signal level.
Step 5
Several types of different external antennas can be found commercially to enhance the signal of the USB modem. You can purchase a suitable copy or make an antenna with your own hands - just have a wire and wire to create a frame. In general, we can say that making an antenna for a modem is quite simple, but the signal does not increase much. The main factor that affects the increase in the signal is the presence of special stations in your locality.
