Broadcom Introduces 5G WiFi Combo Chip for Smartphones and Tablets

Broadcom introduced the BCM4335, the industry's first 5G WiFi combo chip for smartphones, tablets, ultrabooks, and other mobile devices.

5G WiFi, the 5th generation of Wi-Fi based on the IEEE 802.11ac standard, is an evolutionary step from the existing 802.11a/b/g/n networks.

The new 40-nm BCM4335 integrates a complete, single-stream 5G WiFi system—including the MAC, PHY, and RF—with Bluetooth 4.0, FM radio, and software on a single silicon die. The 'platform-agnostic' design and integration of the MAC, PHY and RF allows the BCM4335 to be added to any smartphone or tablet regardless of the application processor used.

The BCM4335 introduces the newest version of Broadcom's wireless coexistence technology. Handset makers can use this technology on 4G LTE cellular platforms to minimize the possibility of radio interference between Wi-Fi, Bluetooth and LTE, which operate in adjacent radio frequencies. Broadcom's Global Coexistence Interface supports the Bluetooth Special Interest Group's LTE coexistence scheme and can be applied to future Broadcom LTE platforms, as well as 4G cellular platforms from other vendors.

Additional highlights:

• Broadcom's TurboQAM technology implements the highest data-rate 256-QAM mode in 2.4 GHz and enables devices equipped with the BCM4335 to deliver 10% faster throughputs than 802.11n speeds when communicating with other 5G WiFi devices.
• Key high-throughput mobility interfaces, including SDIO 3.0, PCIe and HSIC, make it suitable for smartphone, tablet and computing platforms.
• PHY rates of 433 Mbps.
• Advanced beamforming, Low-Density Parity Check (LDPC) code and Space-Time Block Code (STBC) support for better coverage and more reliable connectivity.
• Built-in media processing to off-load host processor.
• Integrated support for Wi-Fi Direct, Wi-Fi CERTIFIED Miracast and Wi-Fi CERTIFIED Passpoint technologies.

The BCM4335 is now sampling to Broadcom's early access customers, with full production expected in Q1 2013. Smartphones and tablets powered by the new BCM4335 are expected to hit the shelves in Q1 2013.
