USI is a key partner of Broadcom in the field of Wi-Fi communication modules, and is leveraging its cutting edge miniaturization technology with the BCM4389 from Broadcom, the first Wi-Fi 6E chip, to develop the WM-BAX-BM-62 SiP module. The WM-BAX-BM-62 SiP is a high performance module with a small footprint designed to meet the ever increasing consumer needs for miniaturization, mobility and efficient data transmission speeds. Samples of the module are scheduled to be provided to leading smartphone brands for evaluation and testing this quarter and to other customers early next year.
An increasing number of smart devices are shrinking in size and Wi-Fi connectivity has become a default feature, driving the industry to grow exponentially with each introduction of the next generation Wi-Fi standard. The Wi-Fi 6 spectrum of application has gradually expanded from smartphones and miniaturized wearable devices to a diverse market segment that require high degrees of reliability and technological iterations, such as automobile, industrial and cloud computing applications. Wi-Fi 6 features technologies such as MU-MIMO (multi-user, multiple input, multiple output) and OFDMA (orthogonal frequency-division multiple access) that provide seamless and faster data transmission. Wi-Fi 6E will extend next generation wireless connections in the 6-GHz band, alleviating many of the Wi-Fi congestion problems with greater and cleaner bandwidth. Broadcom announced the BCM4389 Wi-Fi 6E chip for mobile devices on February 2020.
The BCM4389 chip is equipped with a host of capabilities including OFDMA modulation technique that helps to shorten the transmission delay when multiple devices are connected at the same time, 1024-QAM (quadrature amplitude modulation) that improves the efficiency and traffic of wireless transmission, with both the downloading speed and the coverage enhanced multiple times to reach the GHz level, and TWT (Target Wake Time) that enables a significant improvement of power efficiency. Wi-Fi 6E can utilize up to 7 super-wide 160 MHz channels in 6-GHz band for faster Wi-Fi speeds and latency reduction. BCM4389 is also compatible with the latest Bluetooth 5.1 MIMO (multiple-input multiple-output), which reduces pairing time and enables automatic adjustment of Bluetooth output power. Together with beamforming, BCM4389 ensures seamless connection and efficient performance for any connected Bluetooth devices.
