BCM4346SW01, as an 802.11ac Wi-Fi solution for mobile devices, is a highly integrated, single-chip, two-stream WLAN CMOS transceiver that supports the IEEE 802.11ac standard, including the 5 GHz band, along with backward compatibility with legacy 802.11a/b/g/n standards. The BCM4346SW01 provides the latest in 802.11ac specifications including MIMO, support for up to 400 Mbps, MU-MIMO, and a highly optimized current consumption.

Application Field

The BCM4346SW01 has applications in both consumer and enterprise-grade mobile devices such as smartphones and tablets. It is designed to support a broad range of devices including smartphones, tablets, ultra-mobile PCs, home and business telecommunications equipment, gaming/media devices, and other mobile applications. The BCM4346SW01 can also be used in embedded devices such as ultramobile, handheld, and wearables. Its small form factor and advanced feature set make it an ideal solution for applications that require low power consumption.

Working Principle

The BCM4346SW01 is a complete system-on-a-chip (SoC) designed to provide wireless connectivity for mobile devices. It incorporates an 802.11ac WLAN MAC, baseband processor, and radio. The BCM4346SW01 also includes a host processor interface, an integrated dual-band power amplifier, and other RF system components. The radio transceiver of the BCM4346SW01 supports two-stream 802.11ac, capable of up to 400 Mbps with MIMO, between the dual-band 2.4 GHz and 5 GHz frequency bands.

The BCM4346SW01 also includes a Power-Save Timer, allowing the user to configure the radio to be able to enter a power-saving mode when inactive after a configurable amount of time. In addition, the BCM4346SW01 features a host-extended Multi-Transducer interface, allowing the device to be used in both proprietary and open-standard systems. This interface is compliant with the 802.11ac/an/ax specifications, allowing customers to leverage existing knowledge and frameworks for their applications.

The BCM4346SW01 is designed to support a wide range of multi-media applications, including VoIP, streaming audio and video, video-conferencing, and others. The device is also capable of supporting the 802.11ac power saving mode features, such as packet aggregation and frame-based reduction, to reduce power consumption. The BCM4346SW01 is also backwards compatible with the 802.11a/b/g/n standards providing seamless inter-operability with legacy equipment.
