Q1301. Given below are two statements regarding 5G technology. Statement I: Massive MIMO (Multiple Input, Multiple Output) is a key technology used in 5G. Statement II: Massive MIMO uses a large number of antennas at the base station to increase network capacity and efficiency. Which of the above statement(s) is/are correct?
Explanation
Massive MIMO is a fundamental technology in 5G that utilizes a large number of antennas at the base station to send and receive more data simultaneously. This approach significantly increases network capacity and improves signal quality for users. By focusing signals directly toward specific devices, Massive MIMO enhances overall efficiency, allowing 5G networks to handle the massive data.

Q1304. What does the term "latency" most appropriately refer to in the context of 5G networks?
Explanation
In mobile networking, latency refers to the time it takes for a data packet to travel from its source to its destination and back. Low latency is a hallmark of 5G, enabling near-instantaneous communication between devices. This is critical for time-sensitive applications like online gaming or real-time control of industrial machinery, where even a tiny delay.
