Gaining access to a WiFi network using a long and complicated password is tedious.
In many cases it won’t even protect the network from unwelcome intruders because the level of protection is too low or unsophisticated. Now researchers at the Massachusetts Institute of Technology (MIT) have come up with a way to negate the need for WiFi passwords, while at the same time making the networks safer to use.

Chronos system controls WiFi access based on location
The work was undertaken by researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL). The team is led by Professor Dina Katabi, and has come up with a system called Chronos.
Chronos allows a WiFi router to work out exactly where all of the adapters connected to it are currently located. The technology could enable WiFi access based on your exact location, rather than using a password.
This would make it far harder for hackers to access your WiFi network from a remote location. The system works out how long it takes for data to reach the access point from a user’s device, before combining data from multiple WiFi bands to improve accuracy. The scientists say that their technique is up to 20 times more accurate than existing technology.
