4x4 and 2x2 802.11be Wi-Fi 7 enterprise access point chips​

The BCM43740 is a 4x4 IEEE 802.11be Wi-Fi 7 MAC/PHY/radio system-on-a-chip (SoC) device, and the BCM43720 is a 2x2 IEEE 802.11be Wi-Fi 7 MAC/PHY/radio system-on-a-chip (SoC) device. The BCM43740 and BCM43720 devices can operate in 2.4 GHz, 5 GHz and 6 GHz bands selectively up to 320 Mhz and 160MHz channel bandwidths, respectively. Taking advantage of Multi-Link Operation (MLO) in addition to multi-user technologies such as downlink and uplink OFDMA and downlink and uplink MU-MIMO, the BCM43740 and BCM43720 deliver better throughput, lower latency, and high reliability to commercial grade devices for enterprise networks. These devices are optimized to be used in enterprise Wi-Fi access points.


  • BCM43740 support 4 streams of Wi-Fi 7
  • BCM43740: 320 MHz channel bandwidth in 2.4GHz, 5GHz, and 6GHz band up to 11.5 Gbps
  • BCM43720 support 2 streams of Wi-Fi 7
  • BCM43720: 160 MHz channel bandwidth in 2.4GHz, 5GHz, and 6GHz band up to 2.8 Gbps PHY rate
  • 4096-QAM modulation
  • Multi-Link Operation (MLO)
  • Automated Frequency Coordination (AFC)
  • Uplink and downlink OFDMA
  • Uplink and downlink MU-MIMO
  • ZeroWait DFS
  • Full compliance to IEEE and WFA Wi-Fi 7 specifications
