Leveraging the Rich Array of 11n Features to Enhance Rate-over-Range

Atheros' new implementation of 11n leverages a variety of range enhancement options to ensure that the high throughput levels achieved with the 3x3 MIMO configuration are maintained across the entire WLAN link.

--  Low Density Parity Check (LDPC) guards against packet loss at every
    point on the link.
--  Maximum Likelihood Demodulation (MLD) optimizes MIMO demodulation to
    boost signal strength at close range.
--  Transmit Beamforming (TxBF) focuses transmit signals to the receiver
    to enhance the link rate at mid-range on the link continuum.
--  Maximal Ratio Combining (MRC) enables the receiver to optimally
    combine the MIMO signal paths, aligning time and phase of the signal
    receive to extend link reliability at longer range.

This effective combination of features results in a median rate-over-range improvement across the entire link of approximately 50 percent versus conventional 2x2 MIMO 11n solutions. Performance is maximized when products on both ends of the link are based on XSPAN with SST3, however the technology provides performance benefits when connected to all 11n solutions, and offers backward compatibility with 11g- and 11a/g-based devices.

"The recently ratified IEEE 802.11n standard provides many implementation options, ranging from 1- to 4- streams to enable unprecedented PHY rates for Wi-Fi(R). The standard also offers multiple techniques to boost transmit and receive capabilities, which help sustain these PHY rates across the wireless link," said Bill McFarland, vice president and chief technology officer of Atheros. "In XSPAN with SST3, we've implemented what we consider to be the most effective combination of these optional features and advanced techniques, to provide a WLAN platform that is best suited to support the connectivity demands of high-quality multimedia."

Serving a Wide Array of Advanced Wireless Applications

The AR9300 family of XSPAN with SST3, designed as the high-performance platform for a broad ecosystem of products, is well suited to serve the needs of multiple applications across markets.

--  PCs -- The new solutions target premium consumer and commercial PC
    platforms in high-end notebooks and desktops. Consumers who use their
    computers as media servers with "media center" applications will enjoy the
    robust coverage that the higher rate-over-range of SST3 provides. In the
    enterprise, commercial PC platforms will benefit from the efficiency of
    quicker downloads and connectivity at longer range, as well as faster
    transfers in peer-to-peer networks to improve workplace productivity.
--  Digital Home -- A variety of networking platforms are supported by the
    AR9300. They include 450 Mbps retail access points and routers, premium
    gateways capable of supporting carrier distribution of Video-over-Wireless
    across the digital home, and a variety of consumer electronic networking
    products such as TVs, set top boxes and gaming consoles able to support the
    most bandwidth-hungry, high-definition video content.
--  Enterprise/SMB -- In the enterprise, Atheros' SST3 technology will
    enable dual-band, dual-concurrent routers to provide wired Ethernet-grade
    performance that supports extended network coverage and enhanced
    productivity.

"With Wi-Fi providing Internet connectivity to just about any multimedia content that a consumer wants, the urge is growing to experience this content wherever they are -- while sitting in an airport, in a school library, or in the bedroom of their home," said Jagdish Rebello, senior director and principal industry analyst of iSuppli. "Along with this demand grows the opportunity for high-performance solutions like XSPAN with SST3, to derive the full performance benefits of the 11n standard, and deliver on the wireless multimedia promise."

Solutions that will comprise the XSPAN with SST3 ecosystem are:

   Digital Home
   AP/Router platforms
     -- AR9380/81-based single-band/dual-band Gigabit Ethernet platforms
   Carrier Gateway & CE platforms
     -- AR9380-based DSL, Cable, Set Top Box and TV solutions
   Enterprise/SMB
   AP/Router platforms
     -- AR9390-based dual-band Gigabit Ethernet POE platforms
   Computing
   Notebook and Desktop platforms
     -- AR9380 Dual-band - PCIe

XSPAN with SST3 Makes Sharing Media Content Easy with Atheros Direct Connect(TM) Technology

All computing solutions based on XSPAN with SST3 support Atheros Direct Connect, enabling notebooks to connect multimedia content directly to other client devices without transmitting through an access point. With the solutions' 450 Mbps PHY rate, Direct Connect can transfer HD content simultaneously to multiple clients, while concurrently being connected to the Internet. This capability significantly advances the usability of the Wi-Fi connection to enable anytime, anywhere sharing of content.

Delivering Low Power Advantages

Despite the AR9300 family's impressive rate-over-range, it delivers exceptionally low power through a variety of techniques implemented both in hardware and software. In solutions for PCs, Atheros has implemented Dynamic MIMO Power Save, which enables power efficiencies by downshifting to engage fewer transceivers when applications do not require the full 3x3 operation. Atheros' SST3 solutions also feature Wake-on-Wireless(TM) to enable the host to sleep for longer periods for enhanced efficiency. In all of the AR9300 networking solutions, Atheros has implemented Unscheduled Automatic Power Save Delivery (UAPSD), which allows PCs to sleep more often and longer when connected to SST3-based routers. And, across the entire family of AR9300 solutions, Atheros has implemented its patented Efficient Power Amplifier(TM) (EPA) technology to lower the power utilization when the PA is integrated onto the chip.

Industry-Leading Throughput for Mobile WLANs

The AR6003 delivers actual end-user throughput up to four times that of mobile WLAN solutions based on 11g. With its 11n capabilities, the AR6003 achieves up to 48Mbps TCP/IP in the 2.4 GHz band in 20 MHz mode, and an unprecedented 85Mbps TCP/IP in 5 GHz in 40 MHz mode.

The new ROCm AR6003 enhances its rate-over-range performance above the coverage improvements inherent in the 802.11n MAC and PHY, by leveraging advanced optional 11n features such as Space Time Block Coding (STBC) and Low Density Parity Check (LDPC). STBC improves downlink performance to the mobile device, while LDPC encoding improves uplink performance of mobile clients to Atheros XSPAN- and Align-based wireless access points (APs). Together, these features increase actual throughput levels over longer distances.

"Wi-Fi isn't just a nice-to-have in handsets and other highly-mobile devices -- it's essential," said Craig Mathias, a Principal with the wireless and mobile advisory firm Farpoint Group (Ashland, MA). "Single-stream 802.11n is the ideal solution in this use case enabling high-performance multimedia applications, and we expect to see hundreds of millions of single-stream products -- from handsets to netbooks, gaming devices, cameras, and eBooks, just to name a few -- ship over the next few years. Atheros is building on its leadership position and catching a big wave here, enabling capabilities that will amaze and delight product designers and consumers alike."

Unparalleled Energy Efficiency

The AR6003 features the lowest current consumption of any 11n mobile WLAN solution on the market today to significantly extend battery life, while supporting the power demands of transmitting large media files. Building on the market-proven power efficiency of the AR6002 combined with the low-power benefits derived from faster transmissions at 11n speeds, the AR6003, like its predecessor, is breaking the power barrier for mobile WLAN. The AR6003 also employs the company's patented on-chip Efficient Power Amplifier(TM) (EPA) technology to reduce the power typically consumed by internal PAs, while delivering the output power of an external PA. The result is an average receive current consumption at 11n rates that is 20 percent lower than that of the AR6002, previously the industry's lowest power mobile WLAN solution.

Atheros AR6003 Goes Beyond Coexistence with Universal Wireless Cooperation(TM)

In designing the AR6003, Atheros implemented a suite of advanced mobile wireless coexistence techniques, known as Atheros Universal Wireless Cooperation, in its firmware to significantly enhance the simultaneous operation of WLAN and Bluetooth in mobile devices. This suite consists of features such as:

--  Shared Rx mechanism -- Improves WLAN and Bluetooth coexistence by
    enabling the AR6003 to route the receive traffic through its internal low
    noise amplifier (LNA) directly to the Bluetooth RF port. As a result, the
    solution is able to optimize mobile WLAN throughput when co-located with
    any Bluetooth chip.
--  Advanced Coexistence Enhancements -- Employing advanced Packet Traffic
    Arbitration (PTA)-focused algorithms, the AR6003 is able to quickly examine
    the contents of WLAN frames to prioritize Wi-Fi traffic and optimize
    throughput, while avoiding interference with Bluetooth operation.
    Additional algorithms significantly improve WLAN rate-over-range
    performance when cooperating with Bluetooth, without compromising
    throughput at close range.

"Leveraging Atheros' innovation, market leadership and expertise in 11n technology, we are pleased to deliver yet another mobile WLAN breakthrough with the AR6003," said Amir Faintuch, vice president and general manager of Atheros' mobile business unit. "With this Align-based solution running on a standard 1500 mAh battery dedicated to Wi-Fi alone, a user could download nearly one terabyte of data. That's equivalent to transferring 250,000 songs or 40 HD-quality movies."

Industry's Smallest 11n Mobile WLAN Solution

Atheros has taken integration to a new level with the AR6003 to enable 11n-class performance in a wider variety of mobile handsets and handheld products. The AR6003 eliminates many external components compared to competitive mobile WLAN solutions. The solution features an integrated, linearized, high-efficiency power amplifier, and power management unit (PMU) on chip enabling direct connection to the battery. The result of this integration is the industry's most compact standalone 11n solution, measuring a miniscule 5mm x 5mm.

The AR6003 is available in single (2.4 GHz) and dual-band (2.4/5 GHz) options in BGA or CSP packages to satisfy a wide array of application design requirements.

--  AR6003G -- 11n 1-stream 2.4 GHz single-band solution, BGA package
