Broadcom announced a 5G WiFi (802.11ac) 2×2 Multiple Input Multiple Output (MIMO) combo chip for mobile devices that delivers 650 Mbps Wi-Fi data throughput and 50 percent better coexistence performance with Bluetooth. The device also offers improved location accuracy down to one meter.
Key Features
- 867 Mbps PHY rate/80MHz channel bandwidth
- Enhanced Wi-Fi and Bluetooth coexistence performance
- Low power PCIe host interface for WLAN; UART for Bluetooth
- Combines two 802.11ac streams at 80MHz channel bandwidth via PCIe interface
- Support for Android, Windows and Chrome operating systems
- Integrated Power Amplifier (PA), Low Noise Amplifier (LNA) and internal TR switch
- Transmit beamforming and Low Density Parity Check Codes (LDPC)
- High accuracy Round Trip Time (RTT) based indoor location technology
- Broadcom TurboQAM implements the highest data rate in 2.4 GHz
- First to enable Angle-of-Arrival direction finding technology on smartphone
“The combination of 5G WiFi and 2×2 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.”
