WISEN-2 2T2R, 2.4G&5G, Wi-Fi 6 + BT 5
高性能 Wi-Fi & BT 芯片
WISEN-2 是高度集成的片上系统（SoC），在单芯片中集成了 2 收 2 发 双频段的 Wi-Fi 6 和 蓝牙 5。
集成的 Wi-Fi MAC/PHY/RF 支持 IEEE802.11ax 标准和 Wi-Fi 联盟 Wi-Fi CERTIFIED 6 版本，以较低的功耗提供高达 1.2Gbps 的数据吞吐率，提高了网络效率，同时保持与之前 IEEE802.11a/b/g/n/ac 标准的兼容性。
蓝牙子系统符合 Bluetooth 5 标准，包括 BT/BLE 链路控制器、基带和射频，支持 BT/BLE 双模工作，内置 Wi-Fi/蓝牙 共存解决方案会统筹协调Wi-Fi和蓝牙的通讯流量，以最大限度地优化两个无线制式同时工作时的信号干扰。
支持多种高速接口（包括 PCIe 2、USB 3.0/2.0 和 SDIO 3.0）以及集成 RF 前端组件（如 PA、LNA 和 Balun），WISEN-2 可以为消费类产品和应用（如电脑、数字电视、机顶盒、高清IP摄像机、无线存储等）提供经济高效紧凑的高性能无线连接解决方案。
