The Union Cabinet recently approved a scheme for creation of a National Optical Fiber Network (NOFN) for providing Broadband connectivity to Panchayats. The objective of the scheme is to extend the existing optical fiber network which is available up to district / block HQ’s level to the Gram Panchayat level initially by utilizing the Universal Service Obligation Fund (USOF). The cost of this initial phase of the NOFN scheme is likely to be about Rs.20,000 crore. A similar amount of investment is likely to be made by the private sector complementing the NOFN infrastructure while providing services to individual users. In economic terms, the benefits from the scheme are expected through additional employment, e-education, e-health, e-agriculture etc. and reduction in migration of rural population to urban areas. As per a study conducted by the World Bank, with every 10% increase in broadband penetration, there is an increase in GDP growth by 1.4%. NOFN will also facilitate implemen...

WiMAX Technology is one of the emerging wireless technology that provide us high speed mobile data and telecommunication services. WiMAX stands for Worldwide Interoperability for Microwave Access and it is based on IEEE 802.16 standards.. Wimax Technology works same as Wi-Fi does but it is more improved and efficient then WiFi and it can route data to Wi-Fi that is Wi-Fi devices can take advantage of WiMAX connection. WiMAX technology providess higher speed connection up to 70 Mbps over the area of 30 miles. There is no need for line of sight connection between subscriber terminals and the base station in WiMAX technology and it can support hundreds if not thousands of subscribers from a single base station. It is also specified in 802.16 standards that it will supports low latency applications such as voice, video, and Internet access at the same time. The bandwidth and range of WiMAX make it suitable for the following potential applications: Providing portable mobile broadband...

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...
