5G is the next-generation wireless cellular technology that will provide faster and more reliable communication with ultra-low latency. A government panel report points out that with 5G, the peak network data speeds are expected to be in the range of 2-20 Gigabit per second (Gbps). This can help in good governance and can lead to higher economic growth in India.
Being a game-changer technology in many aspects, be it an economy or a science and technology or development, knowing about it is very important from an exam point of view. So let us look at the topic in detail.
What is 5G technology?
- 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
- 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.
- It’s a unified platform which is much more capable than previous mobile services with more capacity, lower latency, faster data delivery rate and better utilisation of spectrum.
The low, mid, and high-frequency spectrum
- 5G mainly works in 3 bands, namely low, mid and high frequency spectrum — all of which have their own uses as well as limitations.
- The low band spectrum has a great promise in terms of coverage and speed of internet and data exchange but the maximum speed is limited to 100 Mbps (Megabits per second).
- So Telcos can use and install it for commercial cell phone users who may not have specific demands for very high speed internet, the low band spectrum may not be optimal for specialized needs of the industry.
- The mid-band spectrum offers higher speeds compared to the low band, but has limitations in terms of coverage area and penetration of signals.
- This band may be used by industries and specialized factory units for building captive networks that can be moulded into the needs of that particular industry.
- The high-band spectrum offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
- Internet speeds in the high-band spectrum of 5G has been tested to be as high as 20 Gbps (giga bits per second), while, in most cases, the maximum internet data speed in 4G has been recorded at 1 Gbps.
Timeline: Evolution from 1G to 5G
- 1G: Launched in the 1980s. Analog radio signals and supported only voice calls.
- 2G: Launched in the 1990s. Uses digital radio signals and supported both voice and data transmission with a Bandwidth (BW) of 64 Kbps.
- 3G: Launched in the 2000s. With a speed of 1 Mbps to 2 Mbps it has the ability to transmit telephone signal including digitized voice, video calls and conferencing.
- 4G: With a peak speed of 100 Mbps-1 Gbps it also enables 3D virtual reality.
- 5G: with a speed of more than 1Gbps, it is capable of connecting entire world without limits.
How is 5G different from 4G?
| 5G | 4G |
| 5G uses utilize much higher radio frequencies of 28 GHz. | 4G uses lower reading frequencies of 700 MHz to 2500 MHz. |
| 5G transfers more data over the air at faster speeds. | 4G speed is lesser with less data transfer. |
| 5G has lower latency i.e the delay before a transfer of data begins following an instruction. Latency for 5G is predicted to be below 10 milliseconds and in best cases around 1 millisecond. | 4G has higher latency as compared to 5G. The latency for 4G is around 20-30 milliseconds. |
| 5G uses a millimeter-wave spectrum which enables more devices to be used within the same geographic area supporting around one million per square kilometer. | 4G supports a lesser number of devices of about 4,000 devices per square kilometer. |
| 5G uses a new digital technology that improves coverage, speed, and capacity. | 4G has led to more congestion and lesser coverage as compared to 5G. |
