Who: Pruthvi chip
What: Developed by Saankhya Labs
When: Announced in the third week of October 2015
Why: To power White-Fi technology devices
Bengaluru-based Saankhya Labs Pvt Ltd. in the third week of October 2015 announced that it developed a chip, named as Pruthvi, to augment capacities of White-Fi devices.
The Pruthvi-based White-Fi devices will be used by Microsoft to extend the reach of internet services in remote areas of the country.
What is White-Fi technology?
• It uses the unused spectrum in frequencies utilised for broadcasting of television signals and use it for the internet. In technology parlance, these unused spectrum spaces are called White Space and thus it is also called TV White Space technology.
• The 200-300 MHz spectrum in the white space can reach up to 10 km as compared to current Wi-Fi technology that allows you a range of about 100 metres. The 200-300 MHz spectrum currently belongs to Doordarshan TV channel and isn’t used at all.
• It can be run on solar power and thus overcome a key hindrance that currently impedes internet service providers, namely the high cost of installation equipment.
