Wi-Fi Gets Simplified Version Numbers and Next Version is Wi-Fi 6

Wi-Fi Gets Simplified Version Numbers and Next Version is Wi-Fi 6

October 03, 2018Mohit Kumar
Do you know what is the latest version of Wi-Fi? It's okay if you don't know. It is — Wi-Fi is 802.11ac. I am sure many of us can't answer this question immediately because the Wi-Fi technology doesn't have a traditional format of version numbers… at least until yesterday. The Wi-Fi Alliance—the group that manages the implementation of Wi-Fi—has today announced that the next version of WiFi standard, which is 802.11ax, will use a simpler naming scheme and will be called WiFi 6. Wi-Fi 6, based on the IEEE 802.11ax standard, will offer higher data rates, increased capacity, good performance—even in dense environments (such as stadiums or public venues) and improved power efficiency, making it perfect choice for smart home and IoT uses). Of course, the updated version names of all previous Wi-Fi standards will now be: 802.11b → Wi-Fi 1 802.11a → Wi-Fi 2 802.11g → Wi-Fi 3 802.11n → Wi-Fi 4, 802.11ac (current) → Wi-Fi 5 This new straightforward approach
WiGig — New Ultra-Fast Wi-Fi Standard Ready to Boost Your Internet Speed in 2017

WiGig — New Ultra-Fast Wi-Fi Standard Ready to Boost Your Internet Speed in 2017

Get ready for faster Internet because the WiFi you know today is about to change and get much, much faster. The WiFi Alliance, a self-described "worldwide network of companies that brings you Wi-Fi," has finally certified " WiGig ," an ultra-fast, short-range wireless network technology that will nearly double Wi-Fi's current top speed. As many as 180 Million devices, including routers, smartphones, laptops, tablets, and other devices, arriving by the end of next year will support WiGig or multi-gigabit Wi-Fi 802.11ad on the 60 gigahertz band, the Alliance announced . This certification program aims to encourage the production of devices and hardware that not only operate in the "less congested" 60 GHz spectrum but can also fall back to the regular Wi-Fi – 2.4 or 5 gigahertz bands – for maximum interoperability. "Wi-Fi has delighted users for more than 15 years, and WiGig now gives users even higher performance in a rich variety of appl
Hey, Poker Face — This Wi-Fi Router Can Read Your Emotions

Hey, Poker Face — This Wi-Fi Router Can Read Your Emotions

September 21, 2016Mohit Kumar
Are you good at hiding your feelings? No issues, your Wi-Fi router may soon be able to tell how you feel, even if you have a good poker face. A team of researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a device that can measure human inner emotional states using wireless signals. Dubbed EQ-Radio , the new device measures heartbeat, and breath to determine whether a person is happy, excited, sad, or angry. Using EQ-Radio, which emits and captures reflected radio frequency (RF) waves, the team bounced waves off a person’s body to measure subtle changes in breathing patterns and heart rates. This data was then run through a bunch of algorithms and a machine-learning process programmed to match a person's behavior to how they acted previously, categorizing the person's emotion as one of the four emotional states: Pleasure, Joy, Anger and Sadness. The impressive part about the technique: EQ-Radio doesn't r
New Long-Range Wi-Fi Standard Offers Double Range to Home Devices

New Long-Range Wi-Fi Standard Offers Double Range to Home Devices

It is a common problem: Home Wireless Router's reach is terrible that the WiFi network even does not extend past the front door of the room. My house also has all kinds of Wi-Fi dead zones, but can we fix it? The answer is: YES . The problem will improve with a future, longer range version of Wi-Fi that uses low power consumption than current wireless technology and specifically targets at the internet of things (IoTs). Global certification network the WiFi Alliance has finally approved a new wireless technology standard called 802.11ah, nicknamed " HaLow ." HaLow: Long Range WiFi Wi-Fi HaLow has twice the range of conventional Wi-Fi and has the ability to penetrate walls that usually create blackspots in our homes. The Wi-Fi Alliance unveiled this latest WiFi technology at the Consumer Electronics Show (CES) in Las Vegas. Although currently used 802.11 Wi-Fi standards commonly operate in frequency bandwidths between 2.4GHz and 5GHz, the n

MIT Scientists: Now You Can See Through Walls with Wi-Fi

October 29, 2015Swati Khandelwal
Forget about Superman's X-rays vision, you can now see through walls using WI-FI device only. Scientists at MIT's Computer Science and Artificial Intelligence Lab ( CSAIL ) have developed a device that uses WiFi signals to effectively see through walls and other obstacles, and identify which persons are standing behind it. Dubbed RF Capture , the new system is enhanced version of their previous methods of capturing movements across a house – technology used by mothers to see their baby's breathing and firefighters to determine if there are survivors in a burning building. How Does RF Capture Work? The working of RF Capture is actually quite simple and relatively straightforward. RF-Capture works by transmitting wireless signals that, upon hitting a person standing behind a wall, are reflected off various body parts and then back to the device for analysis to piece together the whole image of people. RF-Capture transmits radio waves that pass thro
