802.11n WLAN DOCSIS 3.0 Gateway Reference Design with TI Puma 5

Ralink, a leading developer of 802.11x chips, announced that its Wi-Fi 802.11n solution – RT2880 iNIC now supports Texas Instruments’ Puma 5 family of DOCSIS® 3.0-based (Data Over Cable Service Interface Specification) cable modem chipsets. TI’s Puma 5 family is the industry’s first DOCSIS 3.0 compliant cable modem chipset providing a flexible and scalable platform that enables equipment manufacturers to meet the market demand for innovative next-generation voice, data and video solutions combined with advanced networking capabilities.

This is Ralink’s first 802.11n enabled gateway platform for high speed DOCSIS 3.0 data and video applications. Cable equipment vendors deploying the new platform will be able to introduce cutting-edge wireless networking technology in the shortest time possible. Multi Service Operators (MSOs) and Cable operators will be able to fully leverage their access network capacity to deliver media-rich services and content to today’s networked user.

“Ralink is leveraging TI’s proven Puma 5 DOCSIS 3.0 compliant products to enable cable manufacturers and MSOs to deliver an 802.11n home networking solution that meets the growing demand for networked multimedia broadcast solutions,” said Ran Senderovitz, TI’s cable business manager. “The Puma 5 family’s flexible architecture allows partners such as Ralink to build on top of our proven DOCSIS 3.0 products leading to the creation of a wide variety of next generation voice, data and video solutions.”

RT2880 iNIC is a System On Chip (SoC) that integrates Ralink’s 802.11n 300 Mbps 2T3R (two transmit, three receive) Baseband and Media Access Control (MAC) chips with a MIPS4K CPU. The RT2880 supports the latest 802.11i security features including Wi-Fi Protected Setup, 802.11e Quality of Service (QoS) features including WMM and WMM-PS for prioritization of voice, video and data. It also supports both the 5GHz and 2.4GHz bands when used with Ralink’s transceivers RT2850 and RT2820, respectively.

“We are very happy to work closely with TI to enable customers to distribute the enhanced bandwidth and services offered by DOCSIS 3.0 with strong 802.11n capabilities poised for applications like triple play and IP service providers,” said Kenny Chiu, Vice President of Worldwide Business Development at Ralink Technology. “RT2880 helps maximize user’s experience by distributing sustained multimedia streams at far reach in the home or office in the presence of intereference and supporting the latest 802.11i security features including WiFi Protected Setup.”

About Ralink tradename of their WLAN solution
The consumer’s appetite for wireless bandwidth is growing and 802.11n is meeting that demand by providing wireless connectivity with PHY rates up to 300 Mbps and actual data throughput of up to 170 Mbps. However, many current wireless routers, Cable/DSL modems, and set top boxes lack the CPU power to support 802.11n’s high throughput capabilities. Enter RT2880′s unique chipset solution, which features iNIC architecture that connects to a host processor’s PCI/Ethernet interface and handles all of the 802.11n processing. The host CPU only needs to run a simple Ethernet-like driver, which saves precious processing power for value added applications.
