Atheros has launched 2-stream 11n AR9287 PCIe and AR9227 PCI that deliver full MIMO transmit and receive performance.
The company said that the two new designs that targets the PC and broadband consumer premises equipment (CPE) markets, integrate the MAC/baseband and radio transceiver, two enhanced MIMO power amplifiers and low noise amplifiers, and the transmit/receive switch, all onto a single chip. As a result these designs will enable a new class of 11n products.
Atheros claims that its AR9287 single-chip PCIe for mid-tier notebook and netbook PCs offers greater performance and value over alternative value-class and mid-tier 11n products, including 1×2 designs. Atheros’ new MIMO design for PCs delivers up to 300Mbps PHY rates in both transmit and receive modes.
According to the company, AR9227 single-chip PCI for the broadband networking market has been designed for entry-level and mid-tier DSL, PON and other broadband-enabled access points (APs), such as residential gateways and cable modems.
The company added that it features more than a 50% reduction in rest of bill of materials (RBOM) costs over competing 11n 2×2, single-band products. RBOM advantage allows carrier equipment manufacturers to provide customers with robust, wireless-enabled residential gateways that meet the demands for design and cost efficiencies.
The company said that the new PCIe offering shares its common software code across its XSPAN portfolio of 1×1, and 2×2 single- and dual-band products that simplifies product design and accelerates time-to-market. It supports Atheros Direct Connect Technology, Windows XP, Vista, 7, Mac OS and Linux operating systems, as well as Cisco Compatible Extensions.
The PCI offering supports Linux. In addition, both the products include support for industry standards WMM (Wi-Fi Multimedia) and Wi-Fi Protected Setup.
Ben Naskar, vice president and general manager of the networking business unit for Atheros, said: Leveraging our world-class integration expertise, Atheros has enhanced our highly successful XSPAN technology, and made it even more efficient. Now an entirely new class of value- and mid-tier devices can benefit from the full MIMO performance and functionality of XSPAN’s 2-stream 11n.
