Dual-Band Wi-Fi

In addition to all the features of the Wireless Gateway 1, the Wireless Gateway 2 offers dual-band Wi-Fi. Dual-band Wi-Fi provides simultaneous Wi-Fi to network devices using both wireless radio bands (2.4 GHz and 5 GHz). Older devices can connect to 2.4 GHz Wi-Fi, while newer devices will enjoy the higher throughput of the 5 GHz band.

Benefits of Dual-Band Wi-Fi

  • Enjoy the greater reach enabled by the new high power Wi-Fi designs for the Wireless Gateway 2: 2.4 GHz and 5 GHz radios.
  • Connect laptops, tablets and other newer devices with higher maximum throughput (200-plus Mbps) using 5 GHz. To learn more about Wi-Fi, see What is Wi-Fi? Common 5 GHz band devices include:
    • Smartphones – iPhone 5, Samsung S3, S4, Samsung Epic
    • Tablets - iPad 2, 3, 4 and Mini, Kindle Fire HD (7 in and 8.9), Samsung Galaxy 10.1, Google Nexus 10, Microsoft Surface RT
    • Laptops - MacBook Air, MacBook Pro (A1278), Dell Latitude E5430, E5500, E5420
  • Experience less interference than 2.4 GHz band with more Wi-Fi channels using the 5 GHz radio.
  • Continue to use older devices that only support 2.4 GHz.
