Question:With reference to 5G Technology , consider the following statements:
(1) 5G or fifth generation networks chiefly operate on two spectrum bands :High and Low.
(2) It uses beam tracking to follow all devices on the network to ensure consistent connection in real-time .
(3)5G networks are also designed to multiple-input multiple-output (MIMO) efficient which improves signal.
Which is/are correct?
(a) 1 and 2
(b) 2 and 3
(c) 1 and 3
(d) 1,2 and 3
Answer : (b)
- Context:
- Reliance Industries CMD Mukesh Ambani announced that the company’s telecom venture Jio has designed and developed from scratch, a complete indigenous 5G solution ready for deployment. This will enable Jio to export 5G solutions to other telecom players globally.
Facts:
- 5G or fifth generation is the latest upgrade in the long term evolution (LTE) mobile broadband networks.
- All 5G networks chiefly operate on three spectrum bands:
- The low-band spectrum has been proven to have great coverage but the maximum speed limit on this band is 100 Mbps (Megabits per second).
- In the mid-band spectrum, though the speeds are higher, but has limitations related to coverage area and penetration of telephone signals into buildings.
- The high-band spectrum offers the highest speed but has extremely limited network coverage area and penetration capabilities.
- The 5G networks will have even faster speeds with latency down to between 1-10 milliseconds. Latency is the time a device takes to communicate with the network, which stands at an average of up to 50 milliseconds for 4G networks across the world.
- It uses beam tracking to follow all devices on the network to ensure consistent connection in real-time for the device.
- 5G networks are also designed to multiple-input multiple-output (MIMO) efficient which improves signal throughput for all devices on the network.
