Celeno Announces 2™ Generation CL1800 Beam Forming 802.11n Chipset – Quadruples Performance of 802.11n Systems


Fully integrated silicon solution powered by OptimizAIR™ expert system enhances 802.11n for whole-home HD video distribution

CES 2010, Las Vegas - Celeno Communications, a leading provider of semiconductors for multimedia Wi-Fi home networking applications, announced today the immediate availability of the CL1800, its second generation 802.11n chipset. The new CL1800 is powered by Celeno’s field-proven OptimizAIR™ technology suite that optimizes 802.11n performance for whole-home HD video distribution applications. Manufacturers and Original Equipment Manufacturers (OEMs) can leverage the CL1800 to enable residential gateways, multimedia home routers, set top boxes, digital video recorders (DVR), networked TVs, wireless HDMI bridges and a variety of other Consumer Electronics (CE) devices with robust, wire-like, HD video distribution throughout the home.
High Performance

The robust chipset builds on the success of the CL1300, Celeno’s first generation HD video Wi-Fi chipset and its field-proven Implicit Transmit Beam Forming technology. The CL1800 quadruples the video throughput/range combination of typical 802.11n systems, reaching over 120Mbps of video throughput at the edge of the home with zero packet errors. The chipset supports up to 8 concurrent HD video streams. Faithful to the CL1300 principles, the second generation CL1800 meets carrier grade performance requirements while maintaining client silicon agnostic operation.
Technical Details

The CL1800 is a highly integrated chipset combining an 802.11n MAC/PHY baseband, dual band radio and a powerful CPU. This architecture gives the manufacturer a powerful, yet cost effective and compact solution. The SoC includes a powerful MIPS processor and complementary software, enabling it to run as a completely self-contained unit. This frees the host CPU from any Wi-Fi MAC processing, hence simplifying integration of the CL1800 into devices such as gateways and DVRs.

Key features of the CL1800 include:

* 2.4GHz/5GHz Dual band
* Up to 3 spatial streams
* PHY rate of up to 450Mbps
* 20MHz/40MHz channel bandwidth
* Transmit digital beam forming
* PCI/PCIe/RGMII/MII/USB interfaces

The OptimizAIR™ features suite builds on top of standard 802.11n and combines several innovative technologies that work together intricately at all layers to boost performance and throughput, as needed to support whole-home HD video streaming. These include Transmit Beam Forming MIMO for increased range, TDM Scheduled MAC to support multiple clients with the appropriate QoS, channel aware rate selection for zero packet error rate, real time antenna diversity for robustness and interference resiliency based on adaptive interference detection, fast channel selection and dynamic 20/40MHz operation. The OptimizAIR™ expert system drives up performance by applying real time packet-by-packet channel estimation to each one of those elements, for fully channel-aware silicon.

The CL1800 was jointly developed with Ralink as part of the companies’ strategic partnership.
Availability and Ordering Information

The CL1800 family of products includes two variants: the high-end CL1830 supports up to three transmit and three receive radios; the cost-effective CL1820 supports two transmit and three receive radios.

The CL1800 and selected reference designs are now available to customers. Celeno will be displaying these products at CES 2010 in Las Vegas (South Hall 4, Booth #36071MP).
