CableLabs Clears SMC’s DOCSIS 3.0 Gateway

Device Bonds 16 Downstreams, Targets Max Speeds of 680 Mbps in North American Cable Systems

SMC Networks emerged from CableLabs certification wave 99 with approval for the Veloxite D3G1604W, a DOCSIS 3.0 wireless gateway capable of bonding 16 downstream channels and four upstream channels.

The device is powered by MaxLinear’s MxL265 Full-Spectrum Capture receiver, making it capable of acquiring channels for bonding across the cable spectrum, up to 1 GHz. SMC confirmed that the model is uses the Intel Puma 6 D3 chipset. Intel also makes a “media gateway” version that bonds up to 24 downstream channels and eight upstream channels. Broadcom is cooking up a D3 chip that can bond up to 32 downstream channels.

When fully-loaded, the 16x4 configuration in the newly-certified SMC D3 gateway to achieve max downstream speeds of 680 Mbps using 6MHz-wide channels, and up to 800 Mbps in EuroDOCSIS systems that use 8MHz-wide channels. The baseline specs show built in 802.11n Wi-Fi, but SMC notes that it has an option for 802.11ac, a new Wi-Fi standard that will support max speeds of 1 Gbps on the home wireless network.

Among known customers, Comcast has historically used SMC to support small business customers.
