A Quick Peek Into The 5G System
The 5G system consists of three main parts:
· Radio Access Network (RAN): Connects mobile devices to the core network using advanced wireless technologies like millimeter waves (mmWaves), Massive input massive output (MIMO) and beamforming.
· Core Network (CN): Provides essential control and management functions, such as authentication, mobility, and routing.
· Edge network: Brings network resources closer to end users, enabling the delivery of low-latency, high-bandwidth services like cloud computing, AI, and IoT.
5G architectures can be categorized into two types: 5G Non-Standalone (NSA) and 5G Standalone (SA). NSA mode leverages existing 4G LTE infrastructure, facilitating rapid 5G deployment, while SA mode offers a pure 5G setup with enhanced capabilities like lower latency and network slicing, fully unleashing the potential of 5G.

Security Challenges And Solutions
Amidst the increased complexity and interconnectedness of 5G networks, new security challenges arise for operators, service providers, and users. These challenges can be addressed through:
· Enhanced Encryption and Authentication: 5G networks employ advanced encryption algorithms, such as 5G AKA. This, alongside the 5G SEAF authentication framework based on network slicing, provides stronger security and privacy assurances.
· Edge Computing: It can achieve low latency, reduced bandwidth, and less energy consumption, by processing and storing data at the network edge.
· AI and Machine Learning (ML): AI and ML can analyze and predict network patterns and anomalies, as well as generate and protect network data and identities.
For a reliable solution to tackle these challenges, consider IPLOOK's 5G core network (5GC). Its advanced capabilities can effectively secure your 5G infrastructure.
