12. Why 5G Is So Much Faster Than 4G
According to the essay, what is a primary trade-off of using high-frequency millimeter waves in 5G?
- They are more expensive to produce.
- They have a shorter range and difficulty penetrating walls.
- They are incompatible with most modern smartphones.
- They increase the latency of the network.
The technology known as "massive MIMO" primarily helps 5G networks by:
- using higher frequency radio waves to carry more data.
- allowing many antennas to handle multiple signals simultaneously.
- connecting everyday home appliances to the internet.
- reducing the physical size of the required cell towers.
The essay states that 5G's extremely low latency is particularly important for:
- downloading large movie files.
- sending and receiving text messages.
- real-time applications like online gaming and remote surgery.
- providing service in remote, rural areas.
How is 5G's design specifically beneficial for the "Internet of Things" (IoT)?
- It uses lower frequencies that can travel through objects more easily.
- It is designed to connect a wide variety of smart devices, not just phones.
- It is the first generation of network technology to support internet access.
- It makes devices like home appliances less expensive to manufacture.
Which of the following is NOT listed in the essay as a reason for 5G's faster speed compared to 4G?
- The use of higher frequency radio waves.
- A smarter design for handling many devices.
- The use of more powerful batteries in smartphones.
- A technology that uses many antennas (massive MIMO).
