It integrates the MAC, media-embedded applications that require minimal baseband, and radio of IEEE 802.11 a/b/g and power consumption and compact size. 22 IEEE 802.11n with Bluetooth 4.0 + HS. It includes a power management unit that simplifies The BCM43242 takes advantage of the high the system power topology and allows for operation throughput and extended range of the Broadcom directly from a 3.3V or 5V supply, which provides second-generation MIMO solution. With MIMO, the flexibility. The BCM43242 includes power saving information is sent and received over two or more schemes such as single-core listen (OCL), single- antennas, simultaneously using the same frequency core demodulation of SISO/STBC packets, and band, thus providing greater range and higher dynamic maximum likelihood (ML) demapping (which throughput, while maintaining compatibility with is based on channel conditions). legacy IEEE 802.11a/b/g devices. This is The BCM43242 implements the highly sophisticated accomplished through a combination of enhanced Enhanced Collaborative Coexistence radio MAC and PHY implementations including spatial coexistence algorithms and hardware mechanisms. multiplexing modes in the transmitter and receiver, As a result, enhanced overall quality for simultaneous and advanced digital signal processing techniques to audio, video, and data transmission for home improve receive sensitivity. The BCM43242 entertainment devices is achieved. architecture, with its fully integrated dual-band radio The WLAN host interface is USB 2.0. The Bluetooth transceiver, supports 2 2 antennas. It also supports host interface options include full-speed USB 1.1 and 20 and 40 MHz channels, allowing for PHY Layer a high-speed UART. throughput up to 300 Mbps.
