Broadcom Corporation today introduced the industry’s first 5G WiFi(802.11ac) 2×2 Multiple Input Multiple Output (MIMO) system-on-a-chip (SoC) for smartphones. The Broadcom BCM4354® SoC will enable manufacturers to deliver twice the Wi-Fi performance of 1×1 MIMO devices used in smartphones today while improving system power efficiency up to 25 percent when using wireless applications. Broadcom will showcase its mobile innovations at Mobile World Congress in Barcelona, February 24-27.
Consumersexpect a fast, always-on smartphone experience. Performance however can be degraded by many factors including how a phone is held or positioned.In the past, MIMO systems have solved these problems on tablets and larger devices by using multiple antennas. With Broadcom’s advanced antenna and PHY design, the BCM4354 can nowdeliver the benefits of 5G WiFi 2×2 MIMO tosmallerplatform designs like smartphones while reducing implementation complexity for designers. This achievement enables the industry’s first practical implementation of 2×2 MIMO on a smartphone, opening the door for a new market segment.
“Smartphones have become the epicenter of today’s digital lifeand consumers are demanding ever increasing levels of performance and sophistication,” said Dino Bekis, Broadcom Vice President, Marketing, Wireless Connectivity Combos. “As a leader in wireless connectivity solutions, Broadcom continues to deliver unprecedented features and capabilities to this demanding and rapidly growing market.”
In addition, Broadcom’s Transmit Beamforming (TxBF) technology further improves rate over range performance in congested environments for data-intense applications. Photo and video uploads to social networking sites, for example, will be twice as fast in crowded sporting events or concert venues.
A version of Broadcom’s BCM4354 SoC supports Rezence™ wireless power technology, developed by the Alliance for Wireless Power (A4WP) which delivers additional wireless freedom. All versions feature a full software platform including support for Android, Windows and Chrome-based operating systems.
The Broadcom BCM4354 is a dual-band combo chip for smartphones and tabletsthat supports5G Wi-Fi 2×2 MIMO, Bluetooth (BT)4.1/BLE, Rezence wireless charging supportand FM radio receiver.Highlights include:
- 867Mbps PHY rate/80MHz channel bandwidth
- SDIO3.0 and low-power PCIe host interfaces for WLAN; UART and USB for BT
- Android, Windows and Chrome-based operating systems support
- Load Density Parity Check Codes (LDPC), Space Time Block Coding (STBC), TurboQAM™ andhigh-accuracy indoor location
The BCM4354 isnow in production.
