What is 'Beamforming' in the context of 5G technology?
Correct Answer: A. Directing a wireless signal toward a specific user
Beamforming is a traffic-signaling system that identifies the most efficient data-delivery path to a user. Instead of broadcasting signals in all directions, it focuses them into a concentrated beam. This reduces interference and improves the efficiency of the high-frequency spectrum.
Which type of AI is expected to be natively integrated into 6G architecture?
Correct Answer: C. Distributed AI
6G is expected to be the first generation to have Artificial Intelligence built into every layer of the network. Distributed AI will help the network self-optimize and manage massive amounts of data autonomously. This integration makes the network smarter and more energy-efficient.
What is the primary advantage of 'Small Cells' in 5G deployment?
Correct Answer: A. They increase coverage in dense urban areas
Small cells are low-power base stations that help extend the range of high-frequency 5G signals. They are placed close together to ensure that walls and trees do not block the connection. This dense deployment is necessary for maintaining consistent mmWave coverage.
In the 5G ecosystem, what does 'eMBB' focus on?
Correct Answer: A. High-definition video and high data rates
Enhanced Mobile Broadband (eMBB) is the 5G service category focused on high data speeds. It enables activities like 4K video streaming and cloud-based gaming on mobile devices. It is the most common feature experienced by regular smartphone users.
What role does 'Edge Computing' play in 5G and 6G networks?
Correct Answer: D. Processing data closer to the source
Edge computing moves data processing tasks from central clouds to the 'edge' of the network near the user. This reduces the distance data must travel, which helps in achieving ultra-low latency. It is essential for technologies that require instant responses, like self-driving cars.
Which generation of mobile networks is expected to support 'Holographic Telepresence'?
Correct Answer: D. 6G
6G will provide the massive bandwidth required to stream 3D holographic images in real-time. This will allow people to appear as lifelike 3D projections during remote meetings. Such technology requires data speeds far beyond what current 5G networks can offer.
What is the 'Latency' in a communication network?
Correct Answer: A. The time taken for a data packet to travel
Latency is the delay before a transfer of data begins following an instruction for its transfer. Lower latency means faster response times, which is critical for online gaming and remote control. 5G significantly reduces latency compared to the previous 4G standard.
Which of the following describes 'Non-Standalone' (NSA) 5G?
Correct Answer: D. 5G that relies on existing 4G infrastructure
Non-Standalone 5G uses the 5G radio frequency but depends on the 4G core network for control functions. This allows carriers to roll out 5G services faster by using their existing 4G investments. Standalone (SA) 5G is the next step where the entire network is 5G-based.
Which 6G concept involves using the human body as an antenna or power source?
Correct Answer: D. Intra-Body Communication
Intra-body communication is a futuristic concept where 6G sensors use the human body's conductive properties. This could be used for advanced health monitoring and wearable technology integration. It represents the ultimate merger of biology and wireless technology.
What is the peak data rate goal for 6G technology?
Correct Answer: D. 1000 Gbps (1 Tbps)
6G is being designed to reach peak data rates of 1 Terabit per second (Tbps). This is 50 to 100 times faster than the peak capacity of 5G networks. Such speeds will enable the instant download of massive datasets and high-fidelity virtual worlds.
