Qualcomm 發表首款 End-to-End 802.11ax Wi-Fi 產品

802.11ax 將是下一代 Wi-Fi 標準，主要關注於網路頻寬擴展、更有效的頻譜使用、在更複雜的環境提升連線品質。由 Qualcomm 所推出的 802.11ax 解決方案 IPQ8074 SOC 與 QCA6290 晶片。

IPQ8074 SOC 主要用於 AP、Gateway 與 Router 等產品，整合了 ARM Cortex-A53 處理器，支援 12-streams (8 5GHz 與 4 2.4GHz)、8×8 MU-MIMO、80 MHz 頻道，並支持 Orthogonal Frequency Division Multiple Access (OFDMA)、1024 QAM 等。

而 QCA6290 則可用在客戶端的網路晶片，為 2×2 MU-MIMO 的解決方案，支持 DBS 與 1024 QAM 有著 1.8 Gbps peak 傳輸率，並提供更好的電池續行力。

很有可能在 2017 年底會看到 Qualcomm IPQ8074 SoC 的網路產品問世，而使用 QCA6290 的客戶端可則是要到 2018 年。

IPQ8074 KEY FEATURES
• Up to 4x capacity to maximize network performance*: Utilizing a 12×12 configuration, uplink and downlink MU-MIMO, and supporting eight 80 MHz streams, the IPQ8074 quadruples capacity*, delivers up to 4.8 Gbps, and maintains fast connections over larger coverage areas.
• Smart features for seamless connectivity: In addition to Qualcomm® Wi-Fi Self-Organizing Network (SON), which simplifies installation, optimizes traffic, and reduces dead spots, the IPQ8074 offers unique features to reduce harmful interference in dense areas with many overlapping Wi-Fi access points.
• All-in-one platform: Integrates an 11ax radio, MAC and baseband,  plus a quad-core 64-bit A53 CPU and dual-core network accelerator to provide a fully-offloaded 11ax subsystem. The 14nm design provides power and size advantages, while a wide range of external WAN and media interfaces allows customers to build a full portfolio of 802.11ax products.

QCA6290 KEY FEATURES
• Up to 4x increase in user throughput in crowded networks*: Supports 2×2 MU-MIMO and realizes the full benefits of the 8×8 MU-MIMO by supporting the advanced 8×8 sounding mechanism.
• Ultra-fast Gigabit speed for richer user experiences: Offers up to 1.8 Gbps peak speeds through Dual Band Simultaneous (DBS) combining 2.4 and 5 GHz bands, and higher order modulation (1024 QAM).
• Reduces power consumption by 2/3rd* through Qualcomm Technologies’ specific optimizations, in addition to the support for the 802.11ax standard power save features.
