4G5Gnätverk

4G5Gnätverk refers to the integration and coexistence of fourth-generation (4G) and fifth-generation (5G) mobile network technologies. This transitional phase is crucial as operators worldwide deploy 5G while maintaining their existing 4G infrastructure. 4G, primarily based on LTE (Long-Term Evolution), provides reliable mobile broadband coverage to a vast majority of the population. 5G, on the other hand, offers significantly higher speeds, lower latency, and greater capacity, enabling new applications like enhanced mobile broadband, ultra-reliable low-latency communications, and massive machine-type communications.

In a 4G5Gnätverk environment, devices can often connect to either 4G or 5G depending on availability, network conditions, and the device's capabilities. This allows for a smoother transition to 5G, ensuring users continue to have connectivity even in areas where 5G coverage is not yet established. Operators utilize various strategies for this integration, including Non-Standalone (NSA) 5G, where 5G relies on the 4G core network, and Standalone (SA) 5G, which uses a dedicated 5G core. The coexistence of these technologies allows for a gradual upgrade path, leveraging existing investments while building towards the full potential of 5G. This hybrid approach ensures a continuous and improving mobile experience for users.
