Product description: Beamforming Technology Add Wireless-AC Peripherals Wireless-AC for Faster Speed and Reliability Wireless-AC offers gigabit Wi-Fi speeds that allow video and music files to stream and sync more quickly, allowing you to stream Netflix content to your HDTV while family members simultaneously download movies on a separate device or play online gameswithout waiting for content to buffer. Beamforming Creates Stronger, Faster Connections The Linksys AC1200 Smart Wi-Fi router features beamforming, an innovative technology that optimizes the wireless signal and strengthens communication between specific devices and the router. Beamforming enables the router to identify and connect directly with other devices, rather than simply sending out wireless signals in a general direction. This results in faster network speeds, better wireless range, and reduced interference from other devices. It also helps extend the battery life of connected devices and reduce their power consumption because data is transferred more quickly., Amazon Renewed is your trusted destination for pre-owned and refurbished products that are inspected and tested to work and look like new.
