Broadcom Corporation unveiled what the company claims as the industry's most powerful 5G Wi-Fi (802.11ac) 2x2 Multiple Input Multiple Output (MIMO) chipset for mobile devices today.

The BCM4358 delivers strong throughput, Bluetooth co-existence performance, and indoor location accuracy, enabling OEMs to design high-end smartphones and tablets with twice the Wi-Fi performance.

Today's content-centric consumer spends an average of four to five hours a day on Wi-Fi, according to ABI Research. With 650Mbit/s Wi-Fi data throughput and 50 per cent better coexistence performance with Bluetooth, consumers can download content two times faster, stream videos with less buffering, and connect to multiple Wi-Fi and Bluetooth devices concurrently (e.g. listen to music while playing a game) without interference issues.

In addition, improved location accuracy down to one metre will allow new and better indoor location-based services to become viable.

"The combination of 5G Wi-Fi and 2x2 MIMO unlocks the full potential of today's smartphones and tablets. These technologies are becoming de facto requirements for connectivity in high-end mobile devices," said David Recker, Broadcom Senior Director, Wireless Connectivity. "With the BCM4358 we are addressing critical multi-radio interference challenges while setting a new bar for performance that reflects Broadcom's continued commitment to be first to deliver the most powerful solutions in the market."

Other features of the chipset include 867Mbit/s PHY rate and 80MHz channel bandwidth; low power PCIe host interface for WLAN; UART for Bluetooth; support for Android, Windows, and Chrome operating systems; and integrated power amplifier (PA), low noise amplifier (LNA), and internal TR switch.

The BCM4358 also transmits beamforming and low density parity check codes (LDPC), has high accuracy round trip time (RTT) based indoor location technology, and is first to enable Angle-of-Arrival direction finding technology on smartphones. Its Broadcom TurboQAM implements the highest data rate in 2.4GHz.

The BCM4358 is now in production and will be shipping in mobile devices available in Q3 2014.
