Lantiq teams with Qualcomm Ateros for gigabit home gateway refernce design
June 13, 2012 // Nick Flaherty
German communications chip designer Lantiq is working with Qualcomm Atheros on a reference design for a gigabit broadband home gateway.
The joint design integrates the Qualcomm Atheros QCA9880 3x3 802.11ac solution and the Lantiq XWAY ARX300 or VRX288 universal gateway chipsets to combine xDSL to the home and WiFi.
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.
“Customer interest confirms that advanced home networks will operate with a mix of wired and wireless technologies that combine to deliver the best possible end-consumer experience," said Dirk Wieberneit, SVP/GM of the CPE Business Unit at Lantiq. "One of the benefits of the Lantiq and Qualcomm Atheros smart integration is that the Wi-Fi subsystem offloads the main processor so that the CPU power is available for other applications.”
The Lantiq XWAY ARX300 and VRX288 are cost-optimized home gateway chipsets supporting either ADSL or VDSL broadband access. It uses a dual processor architecture with application processor CPU and dedicated 32bit protocol processing engine that assures wirespeed Gigabit routing performance with zero load on the application processor. It also includes a VDSL2 technology with advanced DSL Physical Layer features and service improvement techniques such as Erasure Decoding & ITU-T Universal Retransmission for up to 100/50 Mbps (downstream/upstream) data rates on VDSL networks to handle multiple IPTV streams and concurrent digital voice and data service access.
Qualcomm Atheros’ QCA9880 3-stream 802.11ac networking chip supports an 80MHz mode and 256 QAM to deliver 1.3 Gbps PHY rates. It uses an integrated CPU core to reduce host processor loads and assist fast, seamless integration of the 802.11ac capability on the gateway platform and 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 maximize coverage, the Qualcomm Atheros 802.11ac solution is easily integrated into the Lantiq platform, which includes the field-proven Universal Gateway software suite.
The integrated and tested reference design will be available to Qualcomm Atheros and Lantiq customers in the third calendar quarter of this year, with an immediate transition to volume production to support customer roll-outs.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
