WiFi security is finally getting an upgrade after 14 years. The Wi-Fi Alliance has officially launched WPA3, the next-generation standard that promises to tackle many of the vulnerabilities that have persisted in wireless networking. Most notably, it brings individualized data encryption that should protect your data against eavesdropping from within the WiFi network. You’ll also get tougher password-based sign-ins through Simultaneous Authentication of Equals, a key establishment protocol that reduces the chances of someone guessing your password — even if it’s lousy.
You probably don’t give it much thought, but your router is one of the most important gadgets in your home—without it there’s no wi-fi for your laptops, your phones, and all the other web-connected devices you’ve got set up.

If Harald Haas is right, in just a few years we’ll all be getting internet through our lightbulbs.
Haas, a professor of mobile communications at the University of Edinburgh in Scotland, has been championing the idea that data can be transmitted through LED lightbulbs for years. Now, he has created a working model of a “Li-Fi” system.
A major partnership with Google putting free Wi-Fi in 400 train stations wasn’t the only major network news coming from India today. The Indian government also announced on Monday that it will pair with Microsoft to bring low-cost broadband connectivity to half a million villages throughout the subcontinent. That should help at least some of the estimated 4 million people that go without internet connectivity every year.
The business of tracking your health with smartwatches or fitness trackers is oppressively hardware-heavy—all those wires, charging docks, and batteries. But that’s poised to change. Soon, it might be the space around you that do the monitoring.
