Broadcom has begun sampling its "5G WiFi" combo chip for smartphones, tablets, ultrabooks and other mobile devices. 
5G Wi-Fi is the 5th generation of Wi-Fi based on the IEEE 802.11ac standard. It significantly improves the wireless range in the home while supporting 3X faster speeds.
The new 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 chip uses the 40nm CMOS process. It also 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.
- 802.11ac. leverages 80 MHz channel bandwidth that is 2 times wider than current 802.11n solutions.
