PM Modi launched 5G in India. This post will tell you everything you need to know for UPSC about 5G. Save it to your notes.
Important definition
- Latency: Time delay in data packets from A to B
- Spectrum: invisible radio frequencies on which wireless signal travels
- Band: range of radio frequency
- Standalone: independent architecture for given G
- Fiberisation: radio towers connected via optical fiber
Basics
- 30-300 GHz (millimeter wave spectrum)
- Peak speed 10 Gbps (4G: 100Mbps)
- Latency: 1 millisecond (4G: 10-100 ms)
- Long Term Evolution: 30-300 GHz (4G: <6GHz)
Evolution
- "Very high" frequency
- High download speed
- Enhanced connectivity
- Low interference from surroundings
- Greater savings for connected devices (push to IoT)
Working, in 3 bands
- Low Band: wide coverage but lower speed (100Mbps), can penetrate through wall/window, long range communication
- Mid Band: Higher speed, limited coverage
- High Band: Highest speed, no penetration through window/wall, short range communication
Advantages
- Improved fintech, agriculture & healthcare experience
- Boost to digital infra -> socio-economic growth
- Job creation
- Tech advancement + higher digital literacy going forward
Challenges
- Standalone v/s Non-Standalone architecture
- Digital divide in our demography
- Critical infrastructure overhaul
- High cost eventually lands on customer
- Fiberisation still a challenge
Scene post auction
- 1.5 lac crore revenue
- Payment in 20 equal instalments, no upfront payment obligation (a biz friendly move by govt.)
- Higher debt inevitable in the sector
Architecture
Standalone (SA) v/s Non Standalone Architecture (NSA)
