Broadcom's expanded portfolio includes the BCM43465 (4x4 11ac MU-MIMO) and BCM43525 (3x3 11ac MU-MIMO) for high-performance access points. With the BCM43465, Broadcom becomes the only vendor able to support 2.2Gbps and four concurrent MU-MIMO (multi-user, multiple input, multiple output) devices, enabling the highest density of client support for the enterprise market. MU-MIMO combined with 160MHz enables devices to fully utilize available bandwidth to deliver more than 2x the performance.

The new chips are further enhanced by NitroQAM technology, Broadcom's 1024-QAM modulation scheme, which gives up to a 25 percent throughput boost over 802.11ac's 256-QAM. In addition, by using a powerful Digital Signal Processing (DSP) based architecture, Broadcom is the first silicon vendor able to perform advanced spectrum capture, analysis and classification right on the chip without impacting performance. Broadcom's Advanced Spectrum Capture Engine (AsCE) allows the chip to identify non-Wi-Fi interference and adjust accordingly, delivering improved reliability and quality.

The portfolio also includes the BCM47452, the industry's lowest-power, smallest and most affordable SoC. The affordability of this chip will help enable all tiers of the enterprise market to transition to 802.11ac. The BCM47452 is the first to integrate the two radios, power amplifiers, as well as a CPU on a single device. Its Real Simultaneous Dual-Band (RSDB) functionality lets OEMs support 2.4- and 5-GHz radio operation concurrently in a single device.
