What is the difference between N1 and N2 interface in 5G? N1 interface in 5G connects User Equipment (UE) with the Access and Mobility Management Function (AMF) for user registration and session management, while the N2 interface connects different AMFs to facilitate handover management, load balancing, and resource allocation within the core network, ensuring seamless … Read more
The primary difference between a gNB (gNodeB) and a base station is that a base station is a term commonly used in earlier generations of wireless technology (2G, 3G, 4G), serving as the central radio equipment for communication with mobile devices, whereas a gNB is specific to 5G networks, representing an advanced and flexible radio … Read more
A standardized network slice in 5G refers to a predefined and regulated virtual network segment with its own resource allocation, service-level agreements, and isolation mechanisms. These slices are created following industry standards like those set by 3GPP, enabling the 5G network to dynamically support diverse use cases such as high-speed internet access, IoT connectivity, and … Read more
Standalone (SA) architecture in 5G is a fully independent network with its own 5G core and radio access, providing end-to-end 5G capabilities. In contrast, non-standalone (NSA) architecture relies on existing 4G infrastructure for initial connectivity and introduces 5G radio access, making it an interim step in the transition to full 5G deployment. What is standalone … Read more
In the 5G era, Self-Organizing Networks (SON) are automated systems that enhance wireless network performance.
