Technologies: How the Tp-Link A9 expands its WiFi range? 

With the two advanced WiFi technologies —concentrating wireless signal strength toward connected devices in order to expand WiFi range— such as Beamforming and MU-MIMO, the Archer A9 also allocates devices to different bands (2.4GHz and 5GHz) for optimal performance. On the other hand, 3×3 MU-MIMO technology is for communicating with multiple MU-MIMO supported devices simultaneously. In contrast, Beamforming + technology is responsible for expanding the WiFi range by focusing on wireless signal strength toward clients.
