Fog Computing for 5G and IoT. As 5G and IoT continue to expand, fog computing is emerging as a critical technology for managing and processing massive amounts of data. Fog computing provides a middle ground between devices and centralized cloud data centers, enabling faster, more efficient processing and storage close to where data is generated. In this article, we’ll explore the role of fog computing in enhancing 5G and IoT capabilities, its key benefits, and how it’s changing the tech landscape.
What is Fog Computing?
Fog computing, or “fogging,” extends cloud capabilities to the edge of the network. It processes data close to the source rather than sending it to a centralized cloud, making it ideal for 5G and IoT applications that demand real-time responses. Fog Computing for 5G and IoT.
- Local Processing: Data is processed near the devices that generate it.
- Reduced Latency: Minimal delays since data doesn’t need to travel to and from distant servers.
- Enhanced Security: Data is kept closer to the source, reducing exposure to cyber threats.
