Broadcom unveils new 5G WiFi 2×2 MIMO SoC for smartphones


broadcom-MIMOWireless and broadband communications company Broadcom introduced a new 5G WiFi system-on-a-chip (SoC) for smartphones that supports 802.11ac and 2X2 MIMO technology for faster wireless performance. The Broadcom BCM4354 chip is the industry’s first implementation of 2×2 MIMO, which delivers twice the performance of 1x MIMO devices and up to 25 percent improvement in energy efficiency.

Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, 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.

Apple’s latest iPad models, the iPad Air and iPad mini with retina display, both ship with 1X MIMO (802.11n), which improves wireless performance by using multiple antennas for sending and receiving signals. This latest Broadcom chip would provide a significant improvement over Apple’s current technology as it provides both 2×2 MIMO and 802.11ac connectivity. Besides 2×2 MIMO, the BCM4354 chip also includes the following features:

  • Bluetooth (BT) 4.1/BLE
  • Rezence wireless charging support
  • FM radio receiver
  • Transmit Beamforming (TxBF) technology to improve performance of data-intense applications in congested environments

Apple uses Broadcom technology throughout its product lineup, including the MacBook Air, Retina MacBook Pro, iMac and iPhone. Though not confirmed, it is possible this Broadcom SoC or a variant of it could land in the iPhone 6, making it the first iOS device to support the newer and faster 802.11 ac WiFi standard.
