Selected IT-Electronics topics from November-December 2014.
Microsoft’s White-Fi technology
- At present, unused spectrum is allotted to television broadcasters. This unused gap is called “White space” Microsoft wants to use it, to beam wifi on a bigger scale of 10 kms radius, with 15 mbps speed at a cost of Rs.10 lakh per router.
- This can provide internet connectivity to villages and tribal areas. But government must give the unused spectrum to tech companies first. Microsoft got trial-permission for Bangalore.
- Telangana Government also interested in this technology for Hyderabad.
- CEO Satya Nadella met Telecom minister Ravi Shankar Prasad for all-India application.
- Recall that other tech-giants too want to increase internet penetration. Example Facebook’s solar-drones (Internet.org) and Google’s helium balloons (Project Loon). Some other companies want to give free internet to non-smart phones using USSD code service.
- Because if more people have internet, then tech giants can make more money through advertisements and e-commerce.
Digital Locker
- In Dropbox, Google drive, Mediafire – you can store your personal files on cloudnetwork.
- Digital Locker aims to store certificates in government’s cloud (online hard disk).
- For example, you store your birth certificate online and provide only the link when you apply for passport.
- Maharashtra government already launched “Maha Digital Locker” where you can login with your Aadhar id. This website can directly upload your certificates to third party website- during job application, passport registration etc.
- Microsoft CEO Nadella wants to help implement this technology at all India level.
- Pro: Paperless operations, no need for photocopies and attestation by gazetted officer.
- Anti: Concerns about online privacy and security.
