WiFi combo chip features Real Simultaneous Dual Band support

By enabling RSDB support, the combo chip 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 maximises the bandwidth at an 867Mb/s 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.

The combo chip also supports Dynamic Frequency Selection, which allows the device to utilise 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 BCM4366 4x4 MU MIMO chip for routers, the BCM4359 delivers an end-to-end solution that can unlock the benefits of next-gen MU MIMO technology.

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

"Our BCM4359 chip extends Broadcom's leadership in high-performance MIMO technology," said David Recker, Senior Director, Wireless Connectivity, Broadcom. "As WiFi 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."

Broadcom will showcase its innovations for the mobile and carrier ecosystem at Mobile World Congress, which takes place from 2^nd to 5^th March in Barcelona.
