MWC 2015: Broadcom expands leadership in MIMO technology with BCM4359

At Mobile World Congress, Broadcom, a provider of semiconductor solutions for wired and wireless communications, announced the launch of 5G WiFi 2×2 Multiple Input Multiple Output (MIMO) combo chip with Real Simultaneous Dual Band (RSDB) support for mobile devices.

Hailed as the industry first, the BCM4359 enables devices to transmit and receive over two bands simultaneously, delivering a dramatically improved experience to highly connected, multi-tasking users, Broadcom said.

With 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.

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,” Recker added.

Broadcom is also introducing a highly integrated and cost-optimized 1×1 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.
