Improve / strengthen 4G signal

In the following brief documentation, we describe how you can improve the reception of your 4G signal.

The 4G transmission technology, also commonly referred to as LTE, enables high wireless data transfer rates. This is particularly beneficial in rural areas, where it often serves as an excellent alternative to DSL or other broadband connections, which are frequently unavailable or provide only low data transfer rates. Unfortunately, in many cases, the strength of the 4G signal in such areas is insufficient, leading to low transfer rates, dropped connections, or overloaded cell towers.

Typically, when signing a contract, your provider will supply a 4G router. For example, Telekom provides devices such as the Speedport Hybrid, LTE, LTE II / 2, B1000, B2000, or Speedbox LTE IV. Vodafone offers the B1000, B2000, GigaCube LTE, or Vodafone R218. O2 supplies the Homebox or the HomeSpot LTE Router. Additionally, there are various provider-independent devices, such as 4G routers from Teltonika, Huawei, ZTE, TP-Link, Asus, and others.

These 4G routers are responsible for receiving the 4G signal. If the 4G signal at your location is too weak, there are several ways to enhance it.

First, try repositioning your 4G router within your house or apartment. Wireless signals are highly susceptible to interference; for example, the sturdy exterior and interior walls of your home can significantly weaken the 4G signal. Trees can also have a substantial impact on signal strength. Place the router near a window facing the nearest 4G cell tower or try positioning it in your attic. This can already lead to a noticeable improvement in the 4G signal.

If this is not sufficient, another very effective way to enhance your 4G signal is to use an external 4G antenna that connects to your 4G router. Ideally, choose an outdoor 4G antenna. As previously mentioned, house walls are a major source of signal attenuation, typically weakening the 4G signal considerably. Installing an antenna outdoors is therefore a highly recommended solution.

Usually, a 4G directional antenna is the most suitable choice, as this type of antenna provides the greatest range and typically achieves the best signal amplification. The ideal setup is to position the antenna so that there is a clear line of sight between it and your provider's 4G cell tower, with as few obstacles as possible in between. The 4G antenna should therefore be mounted as high as possible and outdoors. If outdoor installation is not feasible, you can also consider installing it in your attic.

To select the right 4G antenna, you first need to determine which 4G frequency band you are using. Currently, there are three different frequency bands: 800 MHz, 1800 MHz, and 2600 MHz. Since 4G antennas are generally optimized for specific frequency bands, it is essential to use an antenna that matches your frequency. Your provider should be able to inform you about the frequency band you are using.

A 4G antenna is connected to your 4G router via a coaxial antenna cable. It is important to use the shortest possible antenna cable to minimize the signal loss caused by the coaxial cable. Measure the required length beforehand to avoid unnecessary signal degradation.

Of course, you can find suitable 4G antennas for all three frequency bands, as well as compatible antenna cables, in our webshop.

We hope this small guide/documentation helps you improve your 4G connection.
