5G Technology — the fifth generation of mobile network technology — offers ultra-fast speeds, extremely low latency, and the ability to connect massive numbers of devices simultaneously. It’s a major leap from previous generations (like 4G LTE), enabling transformative advances in fields like smart cities, autonomous vehicles, virtual reality, and the Internet of Things (IoT).
📡 What is 5G?
5G is the next step in wireless communications, designed to:
-
Deliver speeds up to 100x faster than 4G
-
Provide ultra-low latency (as low as 1 millisecond)
-
Support 1 million devices per square kilometer
-
Ensure more reliable and energy-efficient connections
