Broadcom’s first Wi-Fi 6E mobile chip doubles speeds, cuts energy use

News Feed

Just ahead of CES 2020 in early January, the Wi-Fi Alliance announced “Wi-Fi 6E” as the official name for 6GHz Wi-Fi — an enhanced version of Wi-Fi 6 that promises to further increase data rates and cut power consumption. Today, Broadcom is announcing the world’s first Wi-Fi 6E mobile chip, BCM4389, a combined Bluetooth and Wi-Fi solution that promises to double Wi-Fi speeds and cut latency in half compared with Wi-Fi 5, as well as slashing energy use compared with prior-generation solutions.

One of the keys to Wi-Fi 6E’s performance gains is the addition of 6GHz spectrum to the 2.4GHz and 5GHz bands that were used in prior-generation Wi-Fi standards. Multiple countries are currently in the process of opening 6GHz frequencies up for Wi-Fi, which will soon enable home and business networks to use wider 160MHz channels — think of them as additional, thicker wireless data pipes.
