Atheros extends 11n advantage to mobile wireless LAN
A few days ago, Atheros CommunicaTIons, a leader in global wireless and wired communications and continuous innovation, released the industry's highest performance mobile WLAN chip: ROCm® single-chip 11n AR6003 series. The AR6003 builds on the success of the industry-leading AR6002 chip, combining ROCm technology's superior throughput, transmission distance and energy efficiency with Align ™ 1-stream 11n's market leadership and expertise. The AR6300 has the industry's highest actual throughput of 85Mbps, making it ideal for demanding multimedia applications on smartphones, mobile games, and other portable consumer electronics products.
With its small footprint, energy saving, and powerful performance, the AR6003 is very helpful to promote the application of Wi-Fi technology in mobile handheld devices, and perfectly fills Atheros ’Align-based 1-stream 11n solution series in the mobile field. blank. Atheros Align technology has been widely adopted by netbooks, notebooks and desktops in at least seven of the top ten PC manufacturers, as well as the routers of the top five network equipment suppliers. Products based on Align technology currently have more than 10 million computers and access points / routers, providing a fast-growing ecosystem for the mobile wireless LAN market, which will enhance the performance of portable devices using Atheros 1-stream 11n solutions .
Leading throughput
The actual user throughput of the AR6003 can be up to four times that of the 11g mobile wireless LAN solution. AR6003 uses its 11n function to achieve 48Mbps and 85Mbps TCP / IP throughput in the 2.4 GHz band / 20 MHz and 5 GHz band / 40 MHz, respectively.
In addition to the technology of expanding coverage inherent in 802.11n MAC and PHY, the new ROCm AR6003 chip also uses space-time block coding (Space TIme Block Coding / STBC) and low density parity check (Low Density Parity Check / LDPC), etc. Advanced features enhance its rate-over-range (transmission rate within a limited range) performance. STBC improves the downlink performance of mobile devices, while LDPC improves the uplink performance of Atheros wireless access points based on XSPAN and Align technology. Together, these features increase the actual throughput over longer distances.
Craig Mathias, head of the Farpoint Group, a wireless and mobile industry consulting company, said: "Wi-Fi is not just a hand-held device and other high-end mobile devices with optional features, but it is necessary. In this case, support for high-performance multimedia Applied 1-stream 802.11n is an ideal solution, and in the next few years, the number of 1-stream products is expected to reach hundreds of millions, ranging from mobile phones to laptops, gaming devices, cameras and e-books, etc. . Atheros relies on its leading position to grasp this huge business opportunity and provides features that surprise both product designers and consumers. "
Unparalleled energy efficiency
The power consumption of the AR6003 is the lowest among all 11n mobile wireless LAN solutions on the market today, which significantly extends battery life and supports the power requirements for transferring large media files. Based on the AR6002's market-proven efficacy, combined with the low-power advantages derived from the faster transmission rate of 11n, the AR6003 also breaks the power barrier of the mobile wireless local area network like the previous generation. The AR6003 also uses Atheros' Efficient Power Amplifier â„¢ / EPA patented technology to reduce the power consumption of the internal power amplifier while providing the output power of the external power amplifier. The end result is that the average reception power consumption at 11n rate is 20% lower than the AR6002, the lowest power mobile wireless LAN solution in the industry.
Universal Wireless CooperaTIon â„¢ provides excellent coexistence performance
When designing the AR6003, Atheros used a set of advanced mobile wireless coexistence technology in its firmware, namely Atheros Universal Wireless CooperaTIon, to significantly enhance the coexistence of wireless LAN and Bluetooth technology in mobile devices. The technology has the following characteristics:
· Shared acceptance mechanism-AR6003 uses its internal low-noise amplifier (LNA) to route received traffic directly to the Bluetooth RF port, improving the coexistence of wireless LAN and Bluetooth technology. Therefore, this solution can optimize mobile wireless LAN throughput performance while coexisting with any Bluetooth chip.
· Advanced coexistence enhancement-AR6003 with Advanced Packet Traffic Arbitration (PTA) algorithm can quickly check the content of wireless LAN data frames to determine the priority of Wi-Fi traffic and optimize throughput performance, while avoiding interference with the Bluetooth module Running. In addition, the rate-over-range performance of the wireless local area network when coexisting with the Bluetooth module is significantly improved by other algorithms, and the short-range throughput is not damaged.
Amir Faintuch, Atheros Vice President and General Manager of Mobile Business, said: "Using Atheros' innovative capabilities, market leadership and expertise in 11n technology, we are pleased to bring another breakthrough in the development of mobile wireless LAN through AR6003 .This Align-based solution, when running on a standard 1500 mAh battery, users can download nearly 1TB of data. This is equivalent to transferring 250,000 songs or 40 high-definition movies. "
The industry's smallest 11n mobile wireless LAN solution
Atheros AR6003 takes integration to a new level to support 11n-level performance on a wide range of mobile phones and handheld products. Compared with other mobile wireless LAN competition solutions, AR6003 eliminates many external devices. The solution integrates a linearized high-efficiency power amplifier and a power management unit (PMU) that supports direct battery connection. The result of this integration has produced the industry's most compact single-chip 11n solution, measuring only 5mm x 5mm.
The AR6003 is available in BGA or CSP packages and is available in single frequency (2.4 GHz) and dual frequency (2.4 / 5 GHz) to meet various application design requirements.
AR6003G – 11n 1-stream 2.4 GHz single-band solution, BGA package AR6003GZ – 11n 1-stream 2.4 GHz single-band solution, CSP package AR6003X – 11n 1-stream 2.4 / 5 GHz dual-band solution, BGA package AR6003XZ – 11n 1-stream 2.4 / 5 GHz dual frequency solution, CSP packageAR6003 supports the sharing of multimedia content anytime and anywhere through Atheros Direct Connect ™ technology
The AR6003 uses Atheros' peer-to-peer Wi-Fi technology for mobile devices, namely Atheros Direct Connect AP Mode. With a 1-stream 11n throughput level of up to 85 Mbps based on Direct Connect, the solution can share multimedia content with other Wi-Fi devices anytime, anywhere, while maintaining an Internet connection for e-mail, web browsing, and file downloads.
