Broadcom BCM6718 4x4 Wi-Fi® 8 (802.11bn) Access Point Chips

Broadcom BCM6718 4x4 Wi-Fi^® 8 (802.11bn) Residential Access Point Chips are 4x4 Wi-Fi 8 MAC/PHY/Radio solutions with a bandwidth of up to 320MHz. The BCM6718 delivers high performance, efficiency, and reliability for the next generation of 802.11bn (UHR) Wi-Fi access points, routers, and extenders. Broadcom BCM6718 access point chips support Wi-Fi 8 802.11bn features, including increased capacity (dynamic sub-band operation, non-primary channel access, inter-AP coordination, and dynamic bandwidth expansion), improved throughput (unequal modulation and UHR MCS17, MSC19, MCS20, and MCS23 rates), and an extended range (extended long range and distributed resource units). These Wi-Fi 8 chips also provide optimized reliability and QoS (including seamless roaming and low latency indication), making wireless connectivity more reliable, responsive, and intelligent.
