Broadcom Inc. announced that the BCM4389 chip enables Wi-Fi 6E phone, the Samsung Galaxy S21 Ultra. The BCM4389 combines the benefits of the sixth generation of Wi-Fi with the pristine 6 GHz band to power the Galaxy S21 Ultra with Wi-Fi speeds over 2 Gbps. The chip also has a unique multi-radio Bluetooth 5 architecture that supports a premium audio experience with Samsung Galaxy Buds Pro, and Tri-Band Simultaneous (TBS) connectivity that improves Wi-Fi and Bluetooth performance and battery utilization.

Wi-Fi 6E, the latest generation of Wi-Fi, delivers multi-gigabit speeds and millisecond latencies by operating in the 6 GHz band. Countries, including the United States and South Korea, have tripled the available Wi-Fi spectrum by opening up 1.2 GHz of spectrum in the 6 GHz band for unlicensed use. This expansion creates seven additional 160 MHz channels for the BCM4389, unlocking the value of Wi-Fi 6E for remote work, education, telemedicine, and gaming.

The Broadcom® BCM4389 and Samsung Galaxy S21 Ultra bring additional benefits to consumers worldwide. The chip delivers multi-gigabit Wi-Fi 6 performance in the existing 5 GHz band with 160 MHz capabilities. It also builds on the success of Broadcom's Wi-Fi 6 solutions, and instantly benefits from the ecosystem of 400 million Wi-Fi 6 Broadcom-enabled phones, PC, tablets, routers, enterprise access points, and carrier gateways around the world.

The BCM4389 was the world's first Wi-Fi chip authorized by the FCC to operate in the 6 GHz band. It is also in the first wave of devices certified by the Wi-Fi Alliance for Wi-Fi 6E operation. In addition to Wi-Fi 6E, Broadcom BCM4389's TBS connectivity architecture brings better Wi-Fi QoS, more precise indoor location accuracy and five times better battery utilization compared to current flagship connectivity solutions.

Its multi-radio Bluetooth 5 architecture creates robust links to audio headsets even in heavily congested locations like subway stations. The BCM4389 is a smartphone Wi-Fi 6E /Bluetooth 5 combo chip. Key features include: Seven Wi-Fi and Bluetooth radios; Support for 2 streams of Wi-Fi 6E; Multi-Radio Bluetooth 5 with antenna beamforming; Tri-Band Simultaneous (TBS) architecture including a dedicated background scan radio for Wi-Fi and Bluetooth; Simultaneous dual-band operation; 2.63 Gbps PHY rate; Operation in 2.4 GHz and 5.1-7.125 GHz unlicensed bands; 160 MHz channel bandwidth; 1024-QAM modulation; OFDMA; MU-MIMO.
