Beamforming Wi-Fi

The EW-7822ULC’s beamforming enables your Wi-Fi signal to be targeted at your adapter for a stronger, more reliable and efficient Wi-Fi connection when it paired with any beamforming router. Meanwhile, beamforming generates directional-targeted Wi-Fi signals, instead of standard Wi-Fi which radiates outwards. This means better audio quality and HD video streaming as you explore your digital wonderland.
