TP-Link AC1900 Wireless WiFi PCIe network Adapter Card for PC with Beamforming and Heatsink Gigabit Ethernet Network Card PCI-e Wifi Antenna Dual 2.4GHz 5GHz IEEE 802.11ac(WDN7280 Archer T9E AC1900)

Introduction:
1. Free Switching between dual-frequency 2.4GH z and 5GHz. Total rate up to 1900Mbps The wireless transmission rate of 2.4GH z is up to 600Mbps, and the wireless transmission rate of 5GHz is up to 1300Mbps. It means that it could work in the 2.4GH z frequency which is long transmission and easy to pass through the wall, and also it could work in the purer and faster 5GHz frequency. It can be freely selected according to the demand, effectively avoiding wireless interference and network congestion, and the wireless signal is more stable and the Internet is more stable. Smooth. 2. CCA air channel detection technology could improve the wireless performance. Using CCA air channel detection technology When wireless signal interference is detected in the vicinity, the bandwidth mode can be automatically adjusted to avoid channel interference, so that the wireless signal is more stable. When the interference disappears, the idle channel can be automatically bundled, and the channel bundling advantage is fully utilized to improve the wireless performance.
3. External detachable antenna to support beamforming technology The TL-WDN7280 has three external detachable antennas for stronger signal performance, more stable performance and more flexible use. Supports beamforming (Beam-forming) technology, which integrates and optimizes the signals received by each antenna to obtain better signal quality and ensure better connection stability and high-speed performance of the terminal.
