Works to enhance the signal for all devices that require Wi-Fi. Expand your existing eero system and add up to 1,000 square feet of Wi-Fi coverage with eero Beacon. Simply plug Beacons into standard power outlets and add them to your eero network for a wider range of fast, secure and reliable Wi-Fi. Since eero Beacons don't have an ethernet port, every eero system requires an eero (1st or 2nd generation) to connect to your modem.
