Broadcom announced the availability of sample chipsets that form complete solutions for the Wi-Fi 7 ecosystem. They cover Wi-Fi routers, home gateways, corporate access points and client devices, more than twice the data transfer speed of Wi-Fi 6 solutions and 6E on the market today. The advantages of the new element base also include reliable communication with low latency and extended range.
Doubling the bandwidth in Wi-Fi 7 is provided by the introduction of channels with a width of 320 MHz. Combined with Automatic Frequency Coordination (AFC) technology, this gives Wi-Fi 7 the ability to organize optimal spectrum distribution for powerful access points and extend the range of equipment operating in the 6 GHz band, both indoors and outdoors.
Broadcom's product portfolio for the Wi-Fi 7 ecosystem includes the BCM67263, BCM6726, BCM43740, BCM43720, and BCM4398 chips. All of them support 4096-QAM modulation and multi-channel operation (MLO), and are fully compliant with the IEEE and WFA Wi-Fi 7 specifications.
The BCM67263 is optimized for home Wi-Fi hotspots. It supports 320 MHz channels and four Wi-Fi 7 streams with one RF module operating in the 6 GHz band. The physical layer interface (PHY) speed reaches 11.5 Gbps. For home access points, the BCM6726 chip is also optimized. It features a radio module that supports the 2.4, 5 and 6 GHz bands. The channel width can be up to 160 MHz, and the PHY speed reaches 5.75 Gbps.
The BCM43740 and BCM43720 chips are optimized for enterprise Wi-Fi hotspots. The first supports four Wi-Fi 7 streams, the second two, the first supports 320 MHz channels, the second supports 160 MHz. The PHY speed reaches 11.5 Gbps and 2.88 Gbps respectively. In both cases, the 2.4 GHz, 5 GHz or 6 GHz bands are available.
Finally, the BCM4398 is a Wi-Fi 7 and Bluetooth 5 combo controller optimized for smartphones. It supports two Wi-Fi 7 streams, 320MHz wide channels. The PHY speed reaches 6.05 Gbps. Declared compliance not only with IEEE and WFA Wi-Fi 7 standards, but also with the Bluetooth Denver standard.
