Broadcom Combo Chip Doubles Wi-Fi Performance for High-end Smartphones and Tablets

BCM4358Broadcom Corporation has released what it calims to be the industry's most powerful 5G WiFi (802.11ac) 2x2 Multiple Input Multiple Output (MIMO) combo chip for mobile devices. The BCM4358 delivers unparalleled throughput, Bluetooth co-existence performance and indoor location accuracy, enabling OEMs to design high-end smartphones and tablets with twice the Wi-Fi performance. Customers today are content-centric and spend an average of 4-5 hours a day on Wi-Fi.

Broadcoms solution enables consumers can download content two times faster, stream videos with less buffering and connect to multiple Wi-Fi and Bluetooth devices concurrently (e.g. listen to music while playing a game) without interference issues.  In addition, improved location accuracy down to one meter will allow new and better indoor location-based services to become viable.

The BCM4358 has low power PCIe host interface for WLAN; UART for Bluetooth, integrated power amplifier (PA), low noise amplifier (LNA) and internal TR switch with the support for Android, Windows and Chrome operating systems. It also has high accuracy Round Trip Time (RTT) based indoor location technology and implements the highest data rate in 2.4 GHz.

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. The BCM4358 addresses 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. Broadcom was the first chip vendor to mass produce a 2X2 MIMO combo chip for smartphones and continues to drive adoption of 802.11ac in all consumer electronic segments. This second-generation innovation demonstrates Broadcom's continued and substantial lead in 2x2 MIMO technology.
