In an effort to keep up with increasing bandwidth demands on customers’ home networks, Comcast has announced a new Cisco wireless gateway that supports 802.11ac and v2.0 of the Multimedia over Coax Alliance (MoCA) standard that supports a home broadband network over coaxial cable.

The new XFINITY Wireless Gateway will be Cisco’s DPC3941T, which includes a 3×3 MIMO design offering three spatial streams and 700Mbps speed across an 80MHz wide wireless data channel — two times faster than Comcast’s current fastest wireless gateway and considerably faster than competing gateways from AT&T and Verizon.

The new gateway includes a built-in DOCSIS 3.0 modem, but Comcast has not shared details about how many channels the unit can bond and it doesn’t support the next generation DOCSIS 3.1 standard.

The wireless gateway will not come free of charge, but Comcast has not indicated what the monthly lease fee will be. Many Comcast customers pay up to $8 a month to lease a wireless gateway/cable modem.

Only customers in selected markets will initially be able to get the new gateway due later this fall, with customers nationwide getting access sometime later. Comcast is inviting those interested to e-mail: [email protected] to learn when the new gateway becomes available.

Comcast’s newest model will support the XFINITY Wi-Fi project which opens up a community Wi-Fi hotspot on a separate wireless channel accessible to the public.

Comcast is expected to install eight million wireless gateways in customer homes by the end of this year.
