CES 2018 The gadgets that impressed us the most on Day 1.
The Consumer Electronics Show opened on Tuesday with thousands of exhibitors showcasing what is arguably the best technology on planet earth at the moment. It is hard to see everything that is on show at Las Vegas over this week, but on Day One we found quite a few gadgets that really impressed us. Here is a list.

Sennheiser Ambeo Smart Headset

Plug these $299 headsets in and anything you record from them on your Apple iPhone camera gets three dimensional audio. Yes, this does not even need extra apps to record its high quality immersive 3D audio. We did try out the audio recorded with these headsets and the results were really impressive. The headset, expected to come to India in the coming weeks, works only on Apple iPhones and an Android version is expected.

WPA3 is coming to Wi-Fi routers in 2018, with better encryption and login management.
Anyone who has ever set up a router is probably familiar with Wireless Protected Access, or WPA encryption. Now the stage is set for WPA3, an improved Wi-Fi security protocol that brings improved security to network devices.

At CES on Monday, the Wi-Fi Alliance announced WPA3, whose improvements will slowly roll out during 2018 in new devices. The Alliance also announced several improvements to the current, but aging WPA2 spec (in place since 2004), to secure it while WPA3-compliant devices move into the market.

WPA's chief improvements include individualized data encryption, so that hackers lurking on public Wi-Fi networks will find it more difficult to listen in on your wireless communications. More importantly, WPA3 also enforces interaction with the network when a password is entered, signalling the hotspot or router that someone is trying to guess your password and enabling limits to be placed on the number of guesses.

Without the protections enabled by WPA3, attackers could simply retry common passwords, such as "123456," until the router or hotspot let them in. With WPA3, the router could be configured to restrict access or even notify you that an attacker (or just a nosy neighbor) was trying to access your network.
