Broadcom Introduces Industry's First 5G WiFi Combo Chip With Real Simultaneous Dual Band Support

Expands Portfolio of 5G WiFi Combo Chips for Smartphones and Tablets

BARCELONA, Spain, March 2, 2015 — (PRNewswire) —  Mobile World Congress

News Highlights:

  • New 2x2 MIMO chip for high-performance smartphone allows users to run applications on two bands simultaneously
  • New 1x1 5G WiFi combo chip delivers speed and range benefits of 802.11ac in mass market smartphones

Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced the industry's first 5G WiFi 2x2 Multiple Input Multiple Output (MIMO) combo chip with Real Simultaneous Dual Band (RSDB) support for mobile devices. The BCM4359 enables devices to transmit and receive over two bands simultaneously, delivering a dramatically improved experience to highly connected, multi-tasking users. Broadcom will showcase its innovations for the mobile and carrier ecosystem at Mobile World Congress in Barcelona, March 2-5. For more news, visit Broadcom's Newsroom.

By enabling RSDB support, the BCM4359 is able to connect to the 5GHz and 2.4GHz bands simultaneously, improving the throughput and latency when using multiple applications at the same time, particularly video streaming and gaming. The BCM4359 also maximizes the bandwidth at an 867 megabit per second (Mbps) PHY rate in two-stream MIMO mode and can quickly switch to RSDB mode for applications that require concurrent multi-band connections for higher quality of service. 

"Our new BCM4359 chip extends Broadcom's leadership in high-performance MIMO technology," said David Recker, Broadcom Senior Director, Wireless Connectivity. "As Wi-Fi and Bluetooth continue to advance and adoption continues to skyrocket, consumers have come to expect a flawless experience when connecting wirelessly. By enabling smartphones and tablets to simultaneously operate in more than one unlicensed frequency spectrum, this advanced 5G WiFi MIMO combo architecture ensures the most highly connected users have the most optimal experience."

The BCM4359 also supports Dynamic Frequency Selection (DFS) which enables the device to utilize additional channels resulting in a faster connection with less interference.  In addition, Broadcom's proprietary Narrow Band technology enables up to a 2x increase in range, which greatly extends the connection distance between devices. When used with the newly announced BCM4366 4x4 MU MIMO chip for routers, the BCM4359 delivers an end-to-end solution that can unlock the benefits of next-generation MU MIMO technology.   

In addition, Broadcom is introducing a highly integrated and cost-optimized 1x1 5G WiFi combo chip for mass market smartphones. The BCM43455 delivers the power and performance benefits of 5G WiFi while reducing the Rest of Bill of Materials (RBOM) costs by up to 50 percent.
