LiFi internet might just be 100 times faster than WiFi Science & Technology

The pilot testing of LiFi internet, an alternative technology to WiFi, has proved that it can send data at up to 1GBps, according to a report in The Telegraph UK. This is almost 100 times faster than the present WiFi technology.

LiFi uses light to beam information via air. The technology was first discovered by Professor Harald Haas of the University of Edinburgh in 2011.

Professor Haas had talked about the idea on TED talks in 2011, which has seen 1.7 million views on YouTube.


ISRO develops hailstorm app to assess crop damage

To fasten payment of crop insurance claims to farmers, the Central government has launched a pilot programme Kisan, which will use satellite and drone-based imaging and other geo-spatial technology to get timely and accurate data on crop yields.

Also to access large-scale damage to standing crops, an Android-based app for collection of data of hailstorm has been launched.The app will be used by State agriculture officials and the data will help the Union Agriculture Ministry in having very fast assessment of damage to crops because of hailstorm.

Initially, the pilot study will be carried out in rice and cotton fields in four districts during the ongoing kharif season in Karnataka (Shimoga), Maharastra (Yavatmal), Haryana (Kurkshetra) and Madhya Pradesh (Seoni). It will also be carried out during the 2015-16 rabi season in eight districts in same States to assess the crop yields of rice, wheat and shorghum.

The programme will be jointly conducted by Mahalanobis National Crop Forecast Centre, Indian Space Research Organisation, India Meteorological Department, State Agriculture Departments and Remote Sensing Centres, Climate Change, Agriculture and Food Security (CCAFS).
