FAQs on 5G Technology
What is 5G Technology?
5G stands for the fifth generation of wireless communication technology. It is the successor to 4G LTE and is designed to deliver:
-
Ultra-fast internet speeds (up to 10 Gbps).
-
Lower latency (as low as 1 millisecond).
-
High network capacity, allowing billions of devices to connect simultaneously.
Simply put, understanding 5G technology means realizing it’s not just faster internet but an enabler of futuristic applications.
How Does 5G Work?
5G works by using higher-frequency radio waves (millimeter waves) and advanced network technologies like small cells, MIMO (multiple input multiple output), and beamforming.
Key points:
-
Millimeter waves carry more data but have shorter ranges.
-
Small cells increase coverage in urban areas.
-
MIMO antennas boost capacity.
-
Beamforming improves signal direction and efficiency.
