THE PRIEST

The Government has approved creation of National Optical Fibre Network (NOFN) for providing broadband connectivity to all Panchayats. The plan is to extend the existing optical fibre network initially upto Panchayats by utilizing the Universal Services Obligation Fund (USOF) and creating an institutional mechanism for management and operation of the UOFN for ensuring non discriminatory access to all service providers. 

The concept In physics, spectrum refers to a range of frequencies at which electromagnetic waves can be transmitted. Such waves—radio waves, infrared and ultraviolet radiation, microwaves and visible light—abound in nature and travel at various frequencies. Ever since scientists learned to generate artificial electromagnetic waves, these have been used to transmit data for various service—cellular telephony, broadcasting, satellite communications and navigation systems. Interference If all these services operated on the same frequency, there would be interference and confusion. “To give an example, humans can hear sound waves between 20 Hz and 20,000 Hz (cycles per second). Since each one of us has a differently pitched voice and uses different inflections, we are able to hear one another even in a crowded place. But if two people were to shout at the same pitch or frequency, they wouldn’t be able,” Bands... To minimise interference, the International Telecommunication Unio...
