恩智浦全新的Wi-Fi 6E三频段SoC有助于充分利用革命性的6GHz频谱来提高许多用例中的性能，例如家庭网状网络、高分辨率音乐和视频流传输、在线游戏、视频通话、数字下载、大数据量Web内容等等。除了接入点应用外，CW641 SoC还为消费者、汽车、工业和物联网（IoT）领域中的高性能Wi-Fi 6E应用奠定了基础。
CW641的主要特点包括：
- 具有4条空间流的4x4 Wi-Fi设备
- 支持6GHz、5GHz和2.4GHz操作
- 160/80/40/20MHz通道带宽
- 4.8Gbps的峰值PHY速率
- 上行和下行OFDMA
- 上行和下行MU-MIMO
恩智浦无线连接解决方案营销主管Larry Olivas指出：“恩智浦Wi-Fi 6E芯片组兼具多GB数据速率、低延迟和更高的多用户性能，可达成客户对于6GHz产品的期望。当今的无线网络应用需要更大的容量，而这些产品可以满足长达十年的需求。作为我们首款支持6GHz频谱的Wi-Fi 6E SoC，CW641可以为多设备、数据密集型应用中的路由器和网关提供拥堵程度更低的波段，进而增强整体Wi-Fi体验。我们的全新芯片组有助于利用这一远离拥堵的全新带宽，为Wi-Fi 6E网络上的设备提高性能并减少干扰。”
ABI Research首席分析师Andrew Zignani表示：“近期未授权的6GHz频谱逐渐可用于Wi-Fi，这给Wi-Fi格局带来了最为激动人心的革命性变化，使得吞吐量、容量、可靠性和服务质量都有了大幅提升。所有这些不仅有助于实现新的无线服务，还能解决该技术当前面临的关键挑战。但是，为了实现这一潜力，Wi-Fi行业需要通过全新的Wi-Fi 6E芯片组来有效地满足市场的各种需求。在支持6GHz基础设施部署方面，恩智浦最新的CW641 Wi-Fi 6E芯片组等解决方案将发挥基础性作用，助力包含终端设备、应用和服务在内的多样性生态系统利用这一巨大的Wi-Fi新机遇。”

NXP Semiconductors announced it is laying the foundation for a new era of Wi-Fi 6 devices that can operate in the 6GHz band with its new CW641 Wi-Fi 6E Tri-Band system-on-chip (SoC). With increasing congestion in the legacy 2.4GHz and 5GHz bands, the US FCC has approved 1.2GHz of unlicensed spectrum for the 6GHz band along with other regions around the world, which will transform the Wi-Fi landscape. NXP is introducing a Wi-Fi 6E device that will make use of this 6GHz band and extend Wi-Fi capacity by bringing higher throughput, increased capacity, reliability, and improved latency.
Designed for access points and service provider gateways, the CW641 unlocks increased speeds of over 4Gbps and multi-user performance in the new 6GHz band, providing greater capacity and lower latency, which dramatically improves the Wi-Fi user experience. Adding 6GHz capabilities to gateway platforms gives service providers options to efficiently partition available bandwidth across devices to ensure optimum user experience for a wide range of applications. Mission critical, high bandwidth, low latency applications like mesh back haul and cloud gaming are ideal for migration to 6GHz, freeing up the 5GHz and 2.4GHz bands for other lower bandwidth applications.
NXP's new Wi-Fi 6E Tri-Band SoC makes it possible to take full advantage of the transformative 6GHz spectrum to boost the performance of in-home mesh networks, streaming high-resolution music and videos, online gaming, video calling, digital downloads, data-heavy web content, and numerous other use cases. Beyond access point applications, the CW641 SoC sets the stage for high performance Wi-Fi 6E applications across consumer, automotive, industrial, and Internet of Things (IoT).
Key features of CW641 include:
- 4x4 Wi-Fi device with 4-spatial streams.
- Supports 6GHz, 5GHz and 2.4GHz operation.
- 160/80/40/20MHz channel bandwidth.
- Peak PHY rate of 4.8Gbps.
- Uplink and downlink OFDMA.
- Uplink and downlink MU-MIMO.
"NXP's Wi-Fi 6E chipset combines multi-gigabyte data rates, low latency, and higher multi-user performance to deliver on customer demands for 6GHz products that address the decade-long need for the greater capacity required in today's wireless networking applications," said Larry Olivas, Head of Marketing for NXP's Wireless Connectivity Solutions. "As our first Wi-Fi 6E SoC to support the 6GHz spectrum, the CW641 enhances the overall Wi-Fi experience by making less congested airwaves available to routers and gateways for multi-device, data-intensive applications. Our new chipset makes it possible to take advantage of this new uncongested bandwidth, which will provide increased performance with less interference for devices on the Wi-Fi 6E network."
"The increased availability of unlicensed 6GHz spectrum for Wi-Fi is the most exciting and transformative change to the Wi-Fi landscape in recent times, bringing about much higher throughput, greater capacity, increased reliability, and improved quality of service, all of which will help enable new wireless services while addressing key challenges currently facing the technology," saidAndrewZignani, Principal Analyst at ABI Research. "However, in order to realize this potential, the Wi-Fi industry requires new Wi-Fi 6E chipsets that can effectively address the varied demands of the market. Solutions such as NXP's latest CW641 Wi-Fi 6E chipset will play a fundamental role in enabling the 6GHz infrastructure rollout, allowing a varied ecosystem of end devices, applications and services to take advantage of this enormous new opportunity for Wi-Fi."
