Understand how 4G works and its limits
What is 4G?
Technology 4G, also known as 4th generation of standards for mobile telecommunications, is the continuation of the 3G and precedes the very recent 5G. It offers a high-speed mobile Internet connection, allowing you to benefit from better data transfer. This includes streaming videos in high definition, browsing the web at high speeds, and downloading applications faster.
How does 4G work?
There 4G uses advanced modulation techniques and antenna arrays to increase the capacity and speed of wireless networks. Technology Long Term Evolution (LTE) is the most widespread for implementing 4G, thus offering better spectral efficiency and higher speeds.
Concretely, 4G works thanks to a network of telecommunications towers which transmit and receive data by radio frequencies. 4G-enabled devices, such as smartphones, tablets or routers, can connect to this network for Internet access. Data is routed through the cellular network to reach remote servers, which then respond by sending the requested information in the same manner.
The limits of 4G
Despite its advantages in terms of speed and connectivity, the 4G still has certain limitations:
- There geographic coverage is not homogeneous, with areas less well served, particularly in rural or sparsely populated areas.
- THE connection speed can be affected by the number of users on the same network, which can cause bandwidth to slow down during peak hours.
- 4G is sensitive tointerference, especially inside buildings or in areas where many networks coexist.
- The deployment of the infrastructure necessary for 4G represents a significant economic investment, both for operators and for governments. This cost may slow or limit deployment in certain regions.
- The consumption ofenergy is higher, which may shorten the battery life of mobile devices.
Improving 4G reception indoors: Tips and Solutions
Understanding the factors affecting 4G reception
The reception 4G inside buildings can be affected by a variety of factors, including the location of telecommunications towers, the construction materials used in your home, and even the weather. Physical obstacles such as thick surrounding walls or metal structures can block or weaken communication signals. It is therefore essential to identify these elements before looking for solutions to improve reception 4G.
Check the location of telecommunication towers
Proximity and orientation to telecommunications towers play a crucial role in the quality of reception 4G. Applications and websites allow you to locate these towers and determine the best positions to receive the signal. Directing your equipment towards the nearest tower can significantly improve reception quality.
Use 4G signal repeaters or amplifiers
Signal repeaters, also known as amplifiers, pick up the signal 4G outside the building to redistribute it inside. They can be very effective in improving reception in areas where the signal is weak or disturbed. It is important to choose a repeater compatible with the frequency used by your mobile operator.
Optimize the location of your phone or modem
The position of your device within a room can influence signal reception. Avoiding direct obstacles, placing your phone or modem near a window and away from electrical appliances can improve reception.
Change service provider or plan
If, despite all your efforts, reception 4G remains poor, consider changing your mobile provider. Some operators cover certain areas better than others. A plan with another network, such as 3G Or 5G, may sometimes provide better reception depending on location.
Install external antennas
It is sometimes possible to install an external antenna to better capture the 4G signal. This type of antenna is placed on the roof and connected to your modem or telephone via cable. However, it is advisable to call on a professional for installation in order to optimize positioning and connections.
