Semiconductor application provider for wireless and broadband communication, Broadcom has introduced the BCM4335, a 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, a step forward from existing 802.11a/b/g/n networks.
It improves the wireless range in the home, allowing consumers to watch HD-quality video from more devices, in more places, simultaneously.
Consumers can now download web content at 3X faster speeds from a mobile device and sync large files such as videos, in lesser time than it would take on a similar 802.11n device.
The 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 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 company said.
Broadcom’s new 5G WiFi combo chip is designed in 40nm CMOS process to offer enhanced wireless capabilities in mobile devices.
BCM4335 comes with company’s new version of wireless coexistence algorithm which reduces radio interference, features "sleep modes" that extend battery life, and processing capabilities as well as off-load power-intensive tasks from the host processor.
Handset makers can also use this technology on 4G LTE cellular platforms to minimise 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.
The TurboQAM technology implements 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 when communicating with other 5G WiFi devices.
BCM4335 includes key mobility interfaces, including SDIO 3.0, PCIe and HSIC, that make it suitable for smartphone, tablet and computing platforms.
It also offers Low-Density Parity Check (LDPC) code and Space-Time Block Code (STBC) support, built-in media processing to off-load host processor and an integrated support for Wi-Fi Direct, Wi-Fi CERTIFIED Miracast and Wi-Fi CERTIFIED Passpoint technologies.
