4G, or the fourth generation of mobile network technology, is a standard for mobile communications that succeeded 3G. Introduced to offer higher data transmission speeds, 4G allows much faster download and upload speeds, improving internet browsing, video streaming, and the use of mobile applications. The 4G technology is based on advanced communication protocols like LTE (Long Term Evolution), which provides a more stable and reliable connection.

In everyday life, 4G has transformed how we use our mobile devices. For example, thanks to 4G, it is possible to watch high-definition videos on platforms like YouTube or Netflix without buffering, make high-quality video calls on apps like Skype or Zoom, and use GPS navigation services with real-time updates. Additionally, 4G supports the use of social media apps, online gaming, quick file downloads, and VoLTE calls.

In Switzerland, 4G has become the norm for mobile connectivity, with coverage extending to almost the entire national territory. Major telecommunications companies like Swisscom, Sunrise, and Salt have heavily invested to ensure that even the most remote areas of the country can benefit from a reliable 4G connection. This has allowed private users and businesses to benefit from fast and stable connectivity, improving access to digital services, online education, and communications. Despite the advent of 5G, 4G remains a fundamental technology to ensure continuous and high-quality connectivity throughout Switzerland.
