Wi-Fi extender - Computer Definition
A device that extends a Wi-Fi signal for greater coverage. A Wi-Fi extender picks up the signals from a specific Wi-Fi access point and, depending on the brand and model of the device, either boosts the signals under the same network name (SSID) or under a new SSID that must be created and configured. Newer extenders support both the 2.4 and 5 GHz frequency bands. See SSID, Wi-Fi and cellular network extender.
