*MoCA: Multimedia over Coax Alliance. MoCA is a universal standard for home networking over the in-home coaxial cable. MoCA can be used to extend the Wi-Fi range, using a Wireless Ethernet Coax Bridge (WECB).

**CAT-iq 2.0: Cordless Advanced Technology. CAT-iq 2.0 is a digital communication standard, used primarily for cordless phone systems. CAT-iq 2.0 handsets can be paired with the Wireless Gateway.

***DLNA Media Server: Digital Living Network Alliance. DLNA is a standard that allows communication and content sharing between DLNA-compatible devices (regardless of manufacturer brand). A DLNA Media Server stores content on an external storage device and shares it with compatible network devices.

Dual-Band Wi-Fi

In addition to all the features of the Wireless Gateway 1, the Wireless Gateway 2 and Wireless Gateway 3 offer 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 powerful Wi-Fi designs of Wireless Gateway 2 (2.4 GHz and 5 GHz (a/n)) and Wireless Gateway 3 (2.4 GHz and 5 GHz (AC)) radios.
  • Connect laptops, tablets and other devices with higher maximum throughput (700-plus Mbps) using 5 GHz (AC). The 5 GHz (AC) enabled band is also backwards compatible with non-AC enabled devices or clients.
  • Experience less interference than 2.4 GHz band with more Wi-Fi channels using the 5 GHz radio.
  • Continue using older devices that only support 2.4 GHz.


Benefits of Dual-Band Wi-Fi (5 GHz AC-enabled)
  • Enjoy the greater reach and throughput enabled by the 802.11 AC capability on the 5 GHz band, which allows for improved throughput and Wi-Fi coverage available on the Wireless Gateway 3.
  • Connect laptops, tablets and other devices with higher maximum throughput (700-plus Mbps) using 5 GHz (AC).
  • 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.
