The TP-LINK TL-WA850RE WLAN repeater has been developed to create extended WLAN with wider cover and greater range by establishing a WLAN infrastructure instead of using multiple cables. The repeater mode is used as the default WLAN mode. The device acts like a relay station taking WLAN signals from a base router or a network access point and boosting them flawlessly to areas which were previously unreachable or difficult to wire.
