Lantiq and Qualcomm Atheros release home gateway reference design

Lantiq and Qualcomm Atheros have collaborated to produce an advanced broadband home gateway reference design. Delivering superior xDSL and in-home Wi-Fi, the joint design integrates the Qualcomm Atheros QCA9880 3×3 802.11ac solution and the Lantiq XWAY ARX300 or VRX288 universal gateway chipsets.

The collaboration provides gateway manufacturers with a complete software and hardware reference design featuring the newest evolution of 802.11 Wi-Fi and proven DSL broadband gateway functionality. With full test and validation of the design by Lantiq and Qualcomm Atheros, original equipment manufacturers (OEMs) can focus effort on value-added features built on a platform that achieves maximum wired and wireless throughput for triple-play broadband services. To ensure end-to-end Gigabit wireless interoperability, the reference design enables manufacturer readiness for the first wave of Wi-Fi certification of 802.11ac products, targeted by the industry for the first quarter of 2013.

The Lantiq XWAY ARX300 and VRX288 are cost-optimised home gateway chipsets supporting either ADSL or VDSL broadband access. They feature a high-performance dual-processor architecture with application processor CPU and dedicated 32-bit protocol processing engine that assures wirespeed Gigabit routing performance with zero load on the application processor.

For the Lantiq ARX300 family features include integrated, flexible 802.11n 2.4GHz WLAN connectivity with up to 300 Mbps provides zero-packet-error rate technology and a “Thick MAC” architecture to offload processor intensive operations from the main CPU.

They all feature VDSL2 technology with advanced DSL Physical Layer features, plus service improvement techniques like Erasure Decoding & ITU-T Universal Retransmission for up to 100/50 Mbps (downstream/upstream) data rates on VDSL networks. This is for handling multiple IPTV streams and concurrent digital voice and data service access.

Qualcomm Atheros’ QCA9880 3-stream 802.11ac networking solution supports 80 MHz mode and 256 QAM to deliver 1.3 Gbps PHY rates.  The QCA9880 features an integrated CPU core to reduce host processor loads and assist fast, seamless integration of the 802.11ac capability on the gateway platform. The QCA9880 also features Qualcomm Atheros’ Wake-on-Wireless (WoW) technology, which enables the gateway to monitor background Wi-Fi traffic while the overall system remains in sleep mode, resulting in a significant reduction in system power consumption. Delivered as a PCIe module that includes an integrated high power amplifier to maximise coverage, the Qualcomm Atheros 802.11ac solution is easily integrated into the Lantiq platform, which includes the field-proven Universal Gateway software suite.
