Consider the following statements:1. The Second Generation (2G) techno...
  • 2G technology was launched in the 1990s which uses digital radio signals and supported both voice and data transmission with a bandwidth of 64 Kbps. Hence, statement 1 is not correct.
    • 1G technology, launched in the 1980s, worked on analog radio signals.
  • 4G was launched in 2009 with a peak speed of 100 Mbps to 1 Gbps and it also enables 3D virtual reality. Hence, statement 2 is correct.
  • 5G technology is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
    • 5G mainly works in 3 bands, namely low, mid and high frequency spectrum — all of which have their own uses as well as limitations.
      • Low band spectrum: It has shown great promise in terms of coverage and speed of internet and data exchange however the maximum speed is limited to 100 Mbps (Megabits per second).
      • Mid-band spectrum: It offers higher speeds compared to the low band, but has limitations in terms of coverage area and penetration of signals.
      • High-band spectrum: It has the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength. Hence, statement 3 is not correct.
