Atheros releases XSPAN 11n solution based on SST3, which can provide the highest performance guarantee for multimedia networking
Recently, Atheros CommunicaTIons, Inc. released its AR9300 series of 11n solutions, which are based on XSPAN technology using Signal Sustain Technology-3 (Signal Sustained Technology / SST3). This new technology from Atheros provides a 450 Mbps transmission rate (PHY rate) based on the 3-stream 11n MIMO configuration and a series of unique features that help expand the bandwidth range, which together enhance and maintain the signal at every point in the wireless signal chain strength. Atheros' SST3 product system is dedicated to providing end-to-end connection services to the customer market, and related solutions will be delay-free media transmission for personal computers and digital home network equipment and various enterprise-level (including large enterprises and small and medium-sized enterprises) network equipment Provides excellent bandwidth and energy efficiency.
Ben Naskar, vice president and general manager of Atheros' network business, said: "Atheros has provided customers with unique advantages with its strong capabilities in many markets such as computers, digital home networks and enterprises. Just as we launched Align very successfully this year Like the 1-stream series of solutions, we are launching an SST3 solution to support end-to-end product connections covering multiple market segments to meet customers' growing demand for wireless infrastructure, help customers expand network capacity, and provide smoothness Video, improve work efficiency and enhance the overall user experience. "
Utilizes rich 11n functions to enhance Rate-over-Range (transmission rate within effective range) performance
Atheros' new 11n implementation utilizes various enhancement options to ensure that the high throughput levels achieved by the 3 × 3 MIMO configuration are maintained throughout the wireless LAN link.
Low-density parity check (LDPC) can effectively prevent the loss of data packets at various points of the link.
Maximum similarity (decision) demodulation (MLD) optimizes MIMO demodulation to increase signal strength at close range.
Transmit beamforming (TxBF) focuses the transmitted signal to the receiver to increase the mid-range link rate.
Maximum Ratio Combining (MRC) enables the receiver to combine MIMO signal paths in an optimal manner, aligning the time and phase of signal reception to improve the reliability of long-range links.
Compared with the traditional 2x2 MIMO 11n solution, this effective combination of functions improves the rate-over-range performance of the entire link by about 50%. If both the sender and receiver products are based on XSPAN with SST3 technology, performance can be maximized, even when connected to a general 11n solution, the technology can still improve performance and is backward compatible with 11g- and 11a / g device of.
Bill McFarland, vice president and chief technology officer of Atheros, said: "The newly introduced IEEE 802.11n standard provides many implementation options from 1-stream to 4-stream to support the unprecedented Wi-Fi transmission rate (PHY rate). The standard also provides a number of technologies to improve the sending and receiving functions, which helps to maintain the transmission rate of the wireless link, "" In XSPAN with SST3 technology, we have implemented what we believe will be these functions and advanced technical options. The most effective combination to provide the most suitable wireless LAN platform for supporting high-quality multimedia connections. "
Supports a wide range of wireless applications
As a high-performance platform designed for a wide range of products, the AR9300 series solution based on XSPAN using SST3 technology is very suitable for supporting many applications across markets.
Personal Computer (PC)-The new solution targets high-end home and business PC platforms in the high-end notebook and desktop markets. Consumers who use PCs as media servers can enjoy the higher rate-over-range performance of SST3 technology. In the enterprise, commercial PC platforms can benefit from faster download and connection speeds over longer distances, as well as faster transmission speeds in peer-to-peer networks, thereby helping to increase work efficiency.
Digital Home-The AR9300 supports various networking platforms, including 450 Mbps access points and routers, advanced gateways that can support wireless video transmission in the digital home, and various consumer electronics products that can support high-definition video content that consumes the most bandwidth, such as TVs , Set-top boxes and game consoles.
Large and medium-sized enterprises-In enterprises, Atheros' SST3 technology can support dual-band, dual-concurrent routers to provide Ethernet-level performance to expand network coverage and improve work efficiency.
Jagdish Rebello, Senior Director and Chief Industry Analyst at iSuppli, said: "With the support of Wi-Fi technology, consumers can get any multimedia content they want through the Internet connection. Now there is an increasing demand for consumers to experience multimedia content anywhere Growth, such as in the airport, campus library, or bedroom at home. As this demand grows, the market opportunities for high-performance solutions, such as XSPAN with SST3 technology, have also increased, taking full advantage of the 11n standard. Performance advantages and promote the development of wireless multimedia. "
The XSPAN solutions that use SST technology are:
Digital home
AP / Router platform
Single-frequency / dual-frequency Gigabit Ethernet router platform based on AR9380 / 81
Carrier gateway and CE platform
DSL, Cable, STB and TV solutions based on AR9380
Enterprises (large enterprises and SMEs)
AP / Router platform
AR9390-based dual-frequency Gigabit Ethernet POE platform
computer
Notebook and desktop platforms
AR9380 Dual Band-PCIe
XSPAN with SST3 technology uses Atheros Direct Connect technology to promote multimedia content sharing
All XSPAN computer solutions based on SST3 technology support Atheros Direct Connect technology, enabling notebooks to connect multimedia content directly to other client devices without going through an access point. Using the solution's 450 Mbps transmission rate (PHY rate), Direct Connect can simultaneously transmit high-definition content to multiple clients while connecting to the Internet. This feature significantly improves the ease of use of the Wi-Fi connection to support content sharing anytime, anywhere.
Provide the advantages of low power consumption
Although the AR9300 series has outstanding rate-over-range performance, it also achieves excellent low power consumption through various technologies of hardware and software. In a solution for personal computers, Atheros has implemented Dynamic MIMO Power Save, a technology that improves power efficiency by reducing the number of transceivers used when 3x3 is not required. Atheros' SST3 solution also has Wake-on-Wireless (wireless wake-up) features to enable the host to sleep longer to improve efficiency. In all AR9300 networking solutions, Atheros has implemented Unscheduled AutomaTIc Power Save Delivery (Unscheduled Automatic Power Saving Mode / UAPSD) technology, which allows PCs to increase the sleep frequency and extend the sleep time when connected to SST3-based routers . In addition, in the entire AR9300 series, Atheros has implemented its patented Efficient Power Amplifier (Efficient Power Amplifier / EPA) technology, which integrates power amplification on the chip to reduce power consumption.
Product launch plan
Atheros will begin offering samples of the XSPAN with SST3 solution in the first quarter of 2010.
