A Needle in a Haystack: How Wi-Fi RTT Takes Indoor Positioning to the Next Level

Earlier this year, the GSMA, the world’s most influential telecom consortium, published a paper detailing <a href="https://www.gsma.com/newsroom/wp-content/uploads//IG.03-v1.0_Whitepaper.pdf" target="_blank">fifteen blockchain use cases for mobile network operators</a>. Some of them were compelling. Others, less so.

Needles in the Blockchain Haystack

As a society, we spend a lot of time looking for things. Individuals search for apartments to rent, cars to buy, and romantic partners to date. Businesses search for customers, employees, and suppliers. Although we tend to approach these searches as if they are unique, we at <a href="http://ncent.io" target="_blank">nCent</a> believe that they appear distinct on the surface but are often subject to similar dynamics on a meta level. Our goal is to enable people to use incentive programs and <a href="https://hackernoon.com/tagged/blockchain" target="_blank">blockchain</a> <a href="https://hackernoon.com/tagged/technology" target="_blank">technology</a> in order to solve some important problems facing the world today. We believe, in particular, that we can help people find higher quality things in a fraction of the time and more efficiently than they might expect.

How We Can Find the Needle in a Haystack, Together

Pinpointing the root cause of application performance problems in a dynamic environment often resembles a complicated game of hide-and-seek. A familiar analogy is that it’s like trying to find a needle in a haystack. This characterization illustrates the challenge but isn’t especially helpful in offering solutions. So, if the root cause of an application problem is the “needle” and the application environment is the “haystack,” how exactly would we go about restoring peak performance?
