Broadcom Corp. rolls the BCM43241 and BCM4334 dual-band combo chips featuring advanced dual-band 2x2 MIMO Wi-Fi technology that utilise both 2.4GHz and 5GHz radio channels to provide whole-home, high speed Wi-Fi for tablet computers and the benefits of concurrent dual-band connectivity for smart phones.

Both of these chips are manufactured in a 40nm process and employ the most advanced power management techniques, thereby significantly increasing battery life in products that use them, according to the company. The chips are targeted at mid- and low-tier devices, bringing a cost effective dual-band implementation to smartphones and an equally cost effective dual stream solution to tablets.

Features such as Wi-Fi Direct and Wi-Fi Display often use the 5GHz frequency band, making dual-band operation essential in portable products. In addition, operating systems like Android and Windows are enabling more sophisticated applications on these devices, making high-speed dual-band wireless connectivity a must.

The Broadcom InConcert BCM43241, targeted at tablets, also features dual-stream technology, utilising two streams per channel to enable twice the throughput and better range than the current generation of products that incorporate single-stream Wi-Fi. While dual-band Wi-Fi dramatically improves the video experience in the mainstream tier, performance smartphones and tablets are expected to further enhance these applications by adopting 5G Wi-Fi for gigabit wireless speeds.

Chips include FM radio, Bluetooth 4.0 and Bluetooth Smart (Bluetooth Low Energy) support for ultra-low-power connectivity with health, fitness and other sensors. Full software support is available for both Android and Windows, with support for Wi-Fi Direct and Wi-Fi Display, and Bluetooth profiles.

Both chips are currently sampling to early access partners, with full production expected in the third quarter of 2012.
