Q: What is the primary frequency range typically used for 5G mmWave technology?
Answer: 24 GHz - 100 GHz
Explanation: 5G mmWave uses high-frequency bands between 24 GHz and 100 GHz to provide ultra-fast data speeds. These waves have a very short range and are easily blocked by physical obstacles like walls. This spectrum is essential for achieving the multi-gigabit speeds promised by 5G.
Q: Which of the following is a major goal of 6G technology compared to 5G?
Answer: Terahertz frequency usage
Explanation: 6G technology aims to utilize the Terahertz (THz) frequency band for even higher bandwidth. This jump in frequency will allow for data rates up to 100 times faster than 5G. It is expected to support advanced applications like holographic communication.
Q: What does the 5G acronym 'URLLC' stand for?
Answer: Ultra-Reliable Low Latency Communications
Explanation: URLLC is a key feature of 5G designed for mission-critical applications like autonomous driving. It ensures that data transmission is highly reliable and occurs with minimal delay. This capability is vital for real-time remote surgery and industrial automation.
Q: Which organization is responsible for setting the global standards for 5G and 6G?
Answer: 3GPP
Explanation: The 3rd Generation Partnership Project (3GPP) develops the technical specifications for mobile networks. It brings together several telecommunications standard development organizations from around the world. Their releases define the features available in each new generation of wireless technology.
Q: What is the theoretical peak data download speed of 5G technology?
Answer: 20 Gbps
Explanation: The theoretical maximum download speed for 5G is approximately 20 Gigabits per second (Gbps). Real-world speeds are usually lower depending on the network conditions and spectrum used. This is a significant jump from the 1 Gbps limit of 4G LTE.
Q: In 5G networks, 'Network Slicing' allows for which of the following?
Answer: Creating virtualized independent networks
Explanation: Network slicing enables operators to create multiple virtual networks on a single physical infrastructure. Each 'slice' can be optimized for specific needs, such as high speed or low latency. This allows one network to serve both low-power IoT devices and high-bandwidth video streaming.
Q: Which frequency range is generally targeted for the research of 6G communication?
Answer: 100 GHz to 3 THz
Explanation: 6G research is focusing on the sub-terahertz and terahertz bands ranging from 100 GHz to 3 THz. Using these frequencies will provide massive capacity for data-intensive future technologies. However, managing signal loss at such high frequencies remains a significant technical challenge.
Q: What is the expected latency target for 6G networks?
Answer: Sub-0.1 milliseconds
Explanation: 6G aims for 'microsecond' latency, which is less than 0.1 milliseconds. This represents a tenfold improvement over the 1 millisecond goal of 5G. Such low latency is necessary for instantaneous machine-to-machine coordination.
Q: Which technology allows 5G to transmit data to many users simultaneously using multiple antennas?
Answer: Massive MIMO
Explanation: Massive Multiple-Input Multiple-Output (MIMO) uses a large array of antennas to increase network capacity. It allows a base station to send and receive many data signals at once. This technology significantly improves signal strength and user experience in crowded areas.
Q: The concept of 'Internet of Senses' is most closely associated with which generation?
Answer: 6G
Explanation: The 'Internet of Senses' envisions using 6G to transmit touch, smell, and taste digitally. It relies on the extreme speeds and low latency that 6G is expected to provide. This will enable fully immersive virtual reality experiences that feel completely real.
