5G Network Slicing


 Introduction

Standard development groups have described network slicing in several ways. However, there is no standard definition of network slicing. In truth, network slicing refers to any initiatives to make networks-as-a-service available based on user demand. Network slicing can enabled primarily by NFV, SDN, cloud computing, and edge computing. NFV give permission for the use of generic hardware for cost-effective implementations of network services. Significantly, SDN enables the separation of the control plane from the data plane to provide efficient and flexible resource management.

 

1. Technology Overview

The basic development of 5G networks is network slicing, which enables operators to virtually split one physical network into several slices. Each slice serves a specific purpose for different service needs, such as ultra-reliable low-latency communications, and more. This flexibility is achieved from two major technologies: Software Defined Networking-SDN and virtualization of Network Functions-NFV. Both manage numerous virtualized sections for various scenarios.




2. Underpinning Security Concepts

It focuses on maintaining separation, building trust and managing entry. Every slice acts as an independent network, decreasing the chances of slices interfering with each other or being compromised by hackers. Authentication, encryption, and real-time threat detection are necessary to protect data within slices. Zero-confidence (Foukas et al., 2017) methods are more commonly employed to enhance operational security.

3. Potential Use Cases

Some of the potential use cases are as follows:

  1. ·       Healthcare: Surgeries which can be done through remote using Ultra-Reliable Low Latency Communications (URLLC) for accuracy and low latency.
  2. ·       Automotive: Autonomous vehicles will be able to do everything with vehicle-to-everything (V2X) communication.
  3. ·       Entertainment: High-defination of video streaming can be available through Enhanced Mobile Broadband (eMBB).
  4. ·       IoT for industrials: Smart factories using massive machine type communications (mMTC) can enable to make easy for automation and monitoring.

 

4. Impact

Positive Impact

  • ·       Increased resource efficiency by tailoring network components for specific purposes.
  • ·       Improved service performance while maintaining high quality requirements.

·       Aided in the development of innovative services in fields such as healthcare, automobiles, and internet-connected products.

Negative Impact

  • ·       The management and security of slices gets increasingly difficult.
  • ·       Slicing sometimes may compete for resources during peak network traffic.

 

5. Security Concerns

When diverse system components do not work effectively together, it creates weaknesses that can be exploited, especially in shared resources and virtualized environments. These vulnerabilities can be exploited by developing attacks, providing significant security concerns. To properly address these issues, it is critical to implement robust security policies with clear standards and protections. Furthermore, regular software updates are required to safeguard computers from the latest threats (Zhang et al., 2019). AI solutions may also be extremely useful by continually monitoring for anomalous activity, allowing for the early detection and avoidance of any security threats. By incorporating strong security procedures, regular upgrades, and powerful AI monitoring, we can assure a safe and robust system environment. Reducing the required security policies, regular Updates and AI- driven detection should be concerned for the security.

Beamforming in IEEE 802.11ay: Revolutionising Wireless Communication

Image
  Description Beamforming is a transformative signal processing technique that is leading the frontier in wireless communication. It forms a part of the IEEE 802.11ay standard, where other than broadcasting signals uniformly in all directions, the function of beamforming is to coherently transmit those signals in the direction of the intended receiver. This focused approach strengthens signals at an incredible level, minimizes interference, and increases the range of wireless networks by unprecedented bounds, especially in environments operating within the millimeter-wave frequency band at about 60 GHz  (Silva et al., 2018) .   Underpinning Concepts The basic principle behind beamforming is the process of making multiple antennas change the signal phase and amplitude at each antenna element. Thereby, the respective signals from each antenna combine constructively in the direction of the intended receiver for a tightly focused beam of radio waves  (Verma et al...
