Study Notes
5G Network Architecture
- 5G network architecture consists of:
- Radio Access Network (RAN): responsible for wireless communication
- Core Network (CN): responsible for data processing and routing
- Edge Computing: processing data closer to the user, reducing latency
- 5G uses a service-based architecture, with Network Function Virtualization (NFV) and Software-Defined Networking (SDN)
- 5G architecture is designed to be flexible, scalable, and programmable
IoT Implications of 5G
- 5G enables massive machine-type communications (mMTC) for IoT devices
- Low-power wide-area (LPWA) technologies, such as NB-IoT and LTE-M, are optimized for IoT devices
- 5G's low latency and high bandwidth enable real-time IoT applications
- IoT devices will benefit from 5G's improved reliability, security, and mobility
Low-Latency Applications of 5G
- Ultra-reliable low latency communication (URLLC) enables applications requiring:
- Latency < 1 ms
- High reliability (e.g., 99.999%)
- Examples of low-latency applications:
- Online gaming
- Real-time video streaming
- Autonomous vehicles
- Remote healthcare
Security Challenges of 5G
- 5G's increased reliance on software and virtualization introduces new security risks
- Increased attack surface due to:
- More devices and connections
- Higher data rates and volumes
- New network slicing and edge computing architectures
- Key security challenges:
- Network slicing and isolation
- Authentication and authorization
- Data encryption and integrity
mmWave (Millimeter Wave) in 5G
- mmWave frequencies (24 GHz, 28 GHz, 39 GHz) offer:
- Higher bandwidth and data rates
- Lower latency and interference
- Smaller cell sizes and increased capacity
- mmWave limitations:
- Limited range and penetration (e.g., through buildings)
- Higher cost and complexity
- mmWave applications:
- High-density areas (e.g., stadiums, cities)
- Fixed wireless access (FWA)
- High-speed data transfer
