TP-Link has officially announced its new WiFi 8 devices, which include the Archer 8 Ultra and the Deco 8 Ultra.
Archer 8 Ultra
The Archer 8 Ultra was designed to deliver speeds that are fast and consistent. It features 19 Gbps of throughput, two 10G ports, and 18 Smart Antennas. According to TP-Link, you can get up to 33% higher throughput than Wi-Fi 7 at the same signal strength.
The Multi-Floor Mode and Range Boost are claimed to provide up to 3,600 sq ft of coverage for up to 200 connected devices.
Users can set it up with an NFC tap using the Tether app, as well as let guests tap for secure WiFi access without ever needing to see your password. The app also lets you monitor network status, manage Parental Controls, and personalize settings.
A hardware-level VPN encrypts your selected devices right on the router, without requiring separate software on every device. There are separate segments that keep IoT devices and guests off your personal network.
There is an Aireal assistant for your home network that continuously monitors and optimizes your connection in real time, and steps in to correct issues on its own. Not sure if I like the idea of having an AI assistant managing my W-Fi!
Archer 8 Ultra is scheduled to launch in select regions in October 2026, and progressively in other regions throughout 2027.
Deco 8 Ultra
The Deco 8 Ultra is a tri-band Wi-Fi 8 mesh system delivering up to 22 Gbps of aggregate wireless speeds and 10 Gbps wired connectivity. A three-pack provides up to 9,800 sq. ft. of whole-home coverage and supports more than 200 connected devices.
The Deco 8 (Wi-Fi 8 Mesh System) will be available in Q1 2027.
What does Wi-Fi 8 offer that Wi-Fi 7 doesn’t?
Wi-Fi 7 is already capable of high throughput, so instead of just trying to push more speed, Wi-Fi 8 was designed to provide a more stable and seamless connection in real-world environments. It will work with current phones, laptops, and smart home gear, but you will see the biggest gains with newer WiFi 8 clients. Although newer clients get the full list of benefits, your whole home network will still improve.
Even though Wi-Fi 7 is fast, it is easily susceptible to abrupt speed degradation as devices move away from the router. With Wi-Fi 8, there are additional MCS (Modulation Encoding Scheme) levels that allow for a more gradual and consistent speed adjustment.
With Wi-Fi 7, interference on one data stream can slow down the entire connection, so to overcome this, Wi-Fi 8 utilizes UEQM (Unequal Modulation) to allow data streams to operate independently. It does this to prevent a single weak signal from impacting the performance of others.
When it comes to mesh systems, Wi-Fi 8 allows access points to communicate and automatically adjust transmit power to reduce interference in overlapping coverage zones. With Wi-Fi 7, devices can get confused as to which signal to lock onto if they are picking up overlapping zones. According to TP-Link, Wi-Fi 8 provides over 30% improvement compared to Wi-Fi 7
