How to improve 4G/5G signal

There can be several reasons for weak 4G network connection, but in rural areas, the problem may be due to weak signals.

Reasons for weak connection can include:

  • Distant location of the 4G base station
  • Heavy traffic at the base station and congested base station
  • Faulty equipment (modem, antenna)
  • Environment that obstructs the signal, such as high mountains, buildings, and other obstacles
  • Materials used in surrounding buildings that block the signal

One way to improve the connection is by first identifying the cause of the connection problem. If the problem is due to poor 4G coverage, you can boost the 4G signal using an antenna connected to the 4G modem.

It's not possible to directly amplify the 4G signal, so you need a router to create a local network between the terminal devices (phones, computers, smart TVs). A WiFi router and modem that receives the 4G signal and distributes it to the terminal devices are suitable for this purpose. A separate, amplified 4G connection that is shared via the router requires its own 4G subscription and SIM card, which are installed in the modem.

An important factor in improving 4G signal is the antenna. You can find different types of 4G antennas suitable for various uses from our selection: directional and omnidirectional antennas. More information on choosing the right antenna can be found in the article How to choose the most suitable 4G/5G antenna?

When improving 4G signal, for example, at a summer cottage, you also need a WiFi system and a separate 4G subscription for the modem so that the 4G connection can be shared over the WiFi connection to end devices, mobile phones, and computers.
