Wi-Fi 6, which came out in 2019, is built for today’s connectivity needs. With speeds up to 9.6 Gbps, it’s much faster than earlier versions. Wi-Fi 6 is also designed to handle more devices at once, which is great for homes with lots of smart gadgets. Features like OFDMA (Orthogonal Frequency-Division Multiple Access) allow multiple devices to share channels more efficiently, while Target Wake Time (TWT) helps extend battery life for connected devices.
How Does Wi-Fi Work?
Wi-Fi is a wireless networking technology that uses radio waves to provide internet access. Devices like routers, modems, and client devices (like smartphones or laptops) communicate through Wi-Fi signals. When you connect to a network, data is sent back and forth between your device and the router. The router acts as the gateway to the internet, making sure that the data you need reaches your device.
How well this process works depends on the Wi-Fi protocol being used. Wi-Fi 6, for example, uses technologies like OFDMA to split the wireless channel into smaller parts so multiple devices can use it at the same time. This reduces delays and makes the network work better overall. Understanding how these protocols work helps you see why upgrading to the latest technology can make a big difference in your internet experience.
Wi-Fi 5 vs. Wi-Fi 6: Key Differences
Speed and Performance
Wi-Fi 6 offers much faster speeds than Wi-Fi 5, with maximum speeds almost three times higher. This means faster downloads, smoother streaming, and more reliable connections, even in homes with lots of connected devices. Whether you're watching high-definition videos, gaming online, or working from home, Wi-Fi 6 gives you the speed you need to keep everything running smoothly.
Latency and Ping
Latency is the time it takes for data to travel from one point to another. With Wi-Fi 6, latency is reduced, meaning your connection is more responsive. If you’re a gamer, you'll want to check latency and check the ping to make sure you’re getting the best performance. Lower latency means actions, like moving in a game or clicking a button, happen more quickly.
Wi-Fi 6 also uses Target Wake Time (TWT), which reduces power consumption by letting devices communicate more efficiently. This is helpful if you have a lot of smart home devices, as it saves energy while keeping everything connected.
