Broadcom chipset

Broadcom has focused most of its 802.11ac WiFi efforts this year on high- and low-end mobile chips. Today, it's swinging that attention back to bigger machinery like PCs and set-top boxes. The company's new BCM4350, BCM43556 and BCM43558 all carry more robust, 2 X 2 MIMO antennas that help them hit 866Mbps speeds and optimize traffic through beamforming. Any differences, Broadcom notes, revolve around everything but the WiFi. The BCM4350 carries a more PC-like set of interfaces that includes Bluetooth 4.0, PCI Express and SDIO 3.0; the BCM43558 drops the PCIe and SDIO in favor of USB 3.0, while the BCM43556 also sheds Bluetooth. Although we don't know which companies plan to use the nimbler wireless technology, it should ship to gadget makers in the second half of this year.
