📶 What is 5G?
5G, short for fifth-generation wireless technology, is the successor to 4G LTE. It is designed to deliver:
- Ultra-fast speeds (up to 10 Gbps, 100x faster than 4G).
- Low latency (as little as 1 millisecond).
- Massive device connectivity (supporting billions of IoT devices).
- Better reliability and improved coverage.
🔑 Key Benefits of 5G
- Enhanced Mobile Experience: Smooth 4K/8K video streaming, AR/VR gaming, and instant downloads.
- Smart Cities: Enabling real-time monitoring of traffic, energy grids, and infrastructure.
- Healthcare: Remote surgeries and telemedicine powered by high-speed, low-latency connections.
- Autonomous Vehicles: Cars that communicate instantly with each other and traffic systems.
