Last January, the Wi-Fi Alliance announced the new Wi-Fi 6E terminology, which operates with the 802.11ax protocol in the 6GHz band. Embarking on these news, Broadcom presented some standard-compliant news during the Consumer Electronics Show (CES) 2020, including the new BCM4389 chipset, officially launched now.
The BCM4389 is the successor to the BCM4375 version (which already had Wi-Fi 6 support) and performs simultaneous operations thanks to the triple band and compatibility with 160MHz channels. Because of these improvements, the new chip promises to reach speeds of more than 2Gbps – reaching a peak of 2.63Gbps.
Despite taking even more tasks than the previous version, Broadcom was able to reduce energy consumption in the new chip by up to 5x through the 16nm process and architectural improvements.
Broadcom expects the BCM4389 to equip "a wide range of Wi-Fi 6 enabled devices", such as home and commercial routers that will be available at the "launch" of the 6GHz band in late 2020.
In addition, of course, to the obvious chip applications on smartphones and computers, the company also expects virtual and augmented reality devices to use Wi-Fi 6E to pave the way "for the future wirelessly connected VR / AR".
The BCM4389 also has Bluetooth functions that use a proximity mode to stay connected to other devices constantly – which also does not use a lot of energy due to the new technologies of the chip. According to Reuters, this will also help to improve phone calls and music streaming on Bluetooth headsets.
