700 MHZ Spectrum – UPSC Prelims

  • 700 MHZ spectrum was put for auction recently.
  • No one bought it because of its high price.
  • The advantage of the 700 MHz spectrum is that the signals travel longer distances than the higher frequencies used by many other wireless systems.
  • Networks using this spectrum require fewer cell towers to reach the same geographic area.
  • In addition, like TV broadcasting, signals in this spectrum penetrate walls easily.
  • The relatively low frequency 700 MHz is considered ideal for enhancing network availability in large, densely built-up cities.
  • It can solve the issue of poor signal penetration inside buildings.
  • However, less data can be transmitted over these radio waves.
  • Higher-frequency transmissions carry more data, but are poorer at penetrating obstacles.
