Broadcom Unveils World’s First Wi-Fi 6E Chipset for Mobile Devices

Leading semiconductor solutions provider, Broadcom Inc, has released the world’s first Wi-Fi 6E / Bluetooth Combo Chipset. 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.

Wi-Fi 6E builds on the rich feature set of Wi-Fi 6, which includes improved performance in crowded environments, advanced roaming capabilities and increased security. This enhancement of Wi-Fi 6 uses new spectrum in the 6 GHz band to deliver multi-gigabit speeds while avoiding congestion with legacy devices. The BCM4389 expands on the accelerated deployment of Wi-Fi 6, delivering a steady, swift and secure consumer experience in tandem with over 150 million smartphones already in the market. With the additional innovations of Wi-Fi 6E, it unlocks high-speed bi-directional video applications and augmented reality.

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.

In yet another first, the device 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.

The three-radio architecture:
  • Enables always-on Bluetooth discovery for faster pairing with accessories and interference mitigation. Phones and headsets can now pair faster.
  • Quickly scans for interference-free Wi-Fi networks to connect to while main Wi-Fi radios provide data, voice and video services. Phones seamlessly switch to networks with better Quality-of-Service (QoS).
  • Improves indoor location accuracy with always-on scanning and little impact on battery life.
  • Enables the BCM4389 to deliver up to five times better battery utilization than current flagship connectivity solutions.

The BCM4389 will benefit from a full ecosystem of Wi-Fi 6E products, including home routers, residential gateways, enterprise access points, and AR/VR devices. The new 6 GHz spectrum band is expected to be operational in the United States in 2020, and a wide range of 6 GHz enabled devices will be available at launch.

Key Features of the BCM4389 Smartphone Combo Chip:
  • 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
  • Simultaneous dual-band operation
  • 2.63 Gbps PHY rate
  • Operation in 2.4 GHz and 5.1-7.125 GHz unlicensed band
  • 160 MHz channel bandwidth
  • 1024-QAM modulation
  • OFDMA
  • MU-MIMO
