The BCM4389 from Broadcom is a Wi-Fi 6E and Bluetooth 5.0 Combo Chip designed for low-power mobile devices and AR/VR devices. Wi-Fi 6E extends the Wi-Fi 6 standard to support the soon-to-be-operational 6 GHz band with wider 160 MHz channel bandwidths that double Wi-Fi speeds and cut latency in half compared to Wi-Fi 5. The BCM4389 delivers over 2 Gbps of real-world speeds and has up to five times better battery utilization, making it an ideal solution for flagship smartphones and future AR/VR devices.
The BCM4389 also brings advanced multi-radio technology to Bluetooth. Inspired by sophisticated Wi-Fi communication techniques such as multiple-input multiple-output (MIMO) and beamforming, the device improves audio performance and range for any connected Bluetooth accessory. Phones equipped with the BCM4389 will provide a seamless, “glitch-free” audio experience with popular Bluetooth headsets even in congested places such as subway stations.
The device also utilizes Broadcom’s new tri-band simultaneous (TBS) connectivity architecture to mobile devices. In addition to having two main Wi-Fi radios and a MIMO Bluetooth radio, this chipset incorporates a third ultra-low-power independent radio for optimizing Wi-Fi and Bluetooth performance.
