Using Ethernet cables between nodes can create a 10 Gbps backbone for the mesh, significantly enhancing stability and performance compared to a purely wireless backhaul. This makes the system well-suited for homes pre-wired with Ethernet or where users are willing to install cables to maximize performance.
Coverage and Device Management
The three-unit pack is rated to cover homes up to 8,500 square feet with seamless Wi-Fi, aiming to eliminate dead zones. The system employs AI-Driven Roaming technology, which automatically steers connected devices to the node with the strongest signal as they move throughout the home, maintaining a single network name (SSID). This is intended to provide uninterrupted connectivity for activities like Voice over IP calls or streaming while moving between rooms.
TP-Link states the system can handle over 200 connected devices simultaneously, catering to the modern smart home filled with phones, computers, TVs, gaming consoles, and numerous IoT devices. The mesh intelligence is designed to distribute the load efficiently to prevent slowdowns as more devices join the network.
Software and Security
