Broadcom's 2X2 MIMO 802.11ac Mobile Chip Delivers 650 Mbps

Broadcom announced a 5G WiFi (802.11ac) 2x2 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 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."
