Broadcom Announces BCM4389 Wi-Fi 6E Client Chipset

The Wi-Fi Alliance announced the new Wi-Fi 6E terminology for 802.11ax operation in the 6 GHz band last month. At CES 2020, Broadcom announced a number of Wi-Fi 6E access point solutions. Today, Broadcom is announcing the BCM4389 client Wi-Fi 6E chipset. Consumers can expect to see the chipset in the next generation of high-end smartphones. We have already covered the advantages of Wi-Fi 6E in terms of lower latency, higher throughput, and the availability of more number of 160 MHz channels in our coverage of the Wi-Fi Alliance announcement at CES.

The BCM4389 builds upon Broadcom's success with the BCM4375, which happens to be the currently leading client Wi-Fi 6 chipset in the smartphone market. In addition to the new 6 GHz support with tri-band simultaneous operation and 160 MHz channel support, the BCM4389 also brings in additional power efficiency, thanks to its 16nm process technology and architectural improvements.
