The 3 x 3 dBi, RP-SMA antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. This router is 2.4 GHz capable. The 2.4GHz band refers to the portion of the radio spectrum between 2.400 and 2.4835 gigahertz. This router operates on both the 2.4GHz and 5GHz frequency bands. It lets you connect devices to the best band for their needs. Wi-Fi 5 uses the 5 GHz band. It uses wider channels and advanced techniques to send data faster.

Real-world AirStation Extreme AC1900 router speeds are lower than its theoretical maximum speed. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
