![]() Plenty of applications utilize their own encryption to protect your data, like encrypted chat apps, HTTPS, your VPN, and others, but it is nice to know that WPA3 creates an additional layer of protection between you and a malicious actor, even if your app isn't encrypted. Previously, public Wi-Fi networks would transmit your information unencrypted, which meant it could conceivably be read by eavesdroppers also connected to the network. Encrypting all of your traffic while on a public Wi-Fi network is also a huge win for privacy and security. However, just because technology is getting better doesn't mean you should be lax - always create the strongest password you can remember. It means that the weak, easily memorable password you picked for your Wi-Fi network is less vulnerable to hackers than it used to be. It makes stronger encryption schemes available for enterprise use.It encrypts your internet traffic on public Wi-Fi networks.It makes weak passwords more resistant to brute-force attacks.WPA3 presents a few significant improvements over WPA2. The Wi-Fi Alliance requires Wi-Fi 6 Certified devices support Wi-Fi Protected Access 3 ( WPA3), the latest security standard. Yes, Wi-Fi 6 is secure, and it is even more secure than previous versions of Wi-Fi. Wi-Fi 6 will also include improved beamforming, for example. If a device is checking whether the channel is all clear and listens in, it may notice a transmission with a weak signal and a different "color." It can then ignore this signal and transmit anyway without waiting, so this will improve performance in congested areas, and is also called "spatial frequency re-use." These are just some of the most interesting things, but the new Wi-Fi standard also includes many smaller improvements. With Wi-Fi 6, wireless access points near each other can be configured to have different Basic Service Set (BSS) "colors." This "color" is just a number between 0 and 7. In this case, the radio listens and waits for a clear signal before replying. Wireless access points near each other may be transmitting on the same channel. Wi-Fi 6 has an improved version of multi-user or MU-MIMO that lets devices respond to the wireless access point at the same time. With Wi-Fi 5, the access point could talk to devices at the same time, but those devices couldn't respond at the same time. This involves multiple antennas, which let the access point talk to multiple devices at once. The new riderless standard also has improved MIMO - Multiple In/Multiple Out. This is achieved through something called Orthogonal Frequency Division Multiple Access, or OFDMA. The Wi-Fi access point can talk to more devices at once. Each of these subchannels can carry data intended for a different device. But here's what's going on under the hood: Wi-Fi 6 can now divide a wireless channel into a large number of subchannels. A Wi-Fi 6 access point with a Wi-Fi 6 device will work better. You don't really need to know the details. ![]() Related: What is WiGig, and How Is It Different From Wi-Fi 6? It could apply to you at home if you have a lot of devices connected to Wi-Fi, or if you live in a dense apartment complex. ![]() ![]() This wouldn't just apply to busy public places. Intel trumpets that Wi-Fi 6 will improve each user's average speed by "at least four times" in congested areas with a lot of connected devices. The new Wi-Fi 6, also known as 802.11ax, incorporates many new technologies to help with this. You're probably going to have slow Wi-Fi. Picture a busy stadium, airport, hotel, mall, or even a crowded office with everyone connected to Wi-Fi. ![]() Wi-Fi tends to get bogged down when you're in a crowded place with a lot of Wi-FI enabled devices. This will also help with low-power " Internet of Things" devices that connect via Wi-Fi. This will conserve power, as it means the Wi-Fi radio can spend more time in sleep mode. When the access point is talking to a device (like your smartphone), it can tell the device exactly when to put its Wi-Fi radio to sleep and exactly when to wake it up to receive the next transmission. A new "target wake time" (TWT) feature means your smartphone, laptop, and other Wi-Fi-enabled devices should have longer battery life, too. ![]()
