Hello Dear Reader, Today I have given an idea about how our country started Satellite-based Education and Training development in 1975-76. Satellite Instructional Television Experiment (SITE): The journey of societal development by ISRO in view of the available TV & Satellite technologies, started with Satellite Instructional Television Experiment (SITE), which was hailed as the largest satellite-based sociological experiment in India during 1975-76. The SITE was the first pioneering effort to provide a system test of direct broadcast technology in India and use satellite television as a medium of education and developmental training program. Under this giant experiment, the TV programs were transmitted from Ahmedabad and Delhi Earth Station via the 'Application Technology Satellite' (ATS-6) covering 200,000 people across 2400 villages scattered in the isolated villages of 20 districts in the cover six states (Rajsthan, Bihar, Orissa, Madhya Pradesh, Karnataka

Hello, My Dear Reader It is one of the best articles from all others Today I have provided depth idea about DECU which stands for ‘Development and Educational Communication Unit’  is an educational body of ISRO. Rapid advancements in the are of information, Communication, and Technologies(ICT) along with the convergence of various technological innovation, system delivery medium …etc.      DECU Perform all the activities to complete our Father of Space Programme Dr. Vikram Sarabhai’s Vision:      ".....There are Some who question the relevance of space activities in developing nations. To us, there is no ambiguity of purpose. We do not have the fantasy of competing with the economically advanced nations in the exploration of the moon or the planets or manned space flights, but we are convinced that, if we are to play a meaningful role nationally and in the a community of nations, we must be second to none in the applications of advanced technologies to the real prob

It’s scarcely twenty years since the first-second generation (2G) digital mobile phones appeared on the market. By the mid–1990s texting was widely adopted, and further, GSM and GPRS based modems became available—albeit only providing slow connectivity no higher than a few kbps. This was the start of the wireless digital data revolution. By the end of the 1990s and into the 2000s, third-generation (3G)   mobile connections became available at speeds of a few 100kbps and WiFi emerged as a means of connecting devices to wireless access points over distances below 20 meters or so. From early WiFi speeds of just a few Mbps, by 2005 we were running at 54Mbps in most implementations and soon to speeds of   300Mbps and higher when MIMO methods emerged in the early 2010s. Smartphones also just keep getting smarter. WiFi and Bluetooth are now considered standard wireless connectivity requirements on smartphones alongside 2G, 3G, and likely fourth-generation (4G) LTE
