The demand for affordable smartphones loaded with Google Android has increased dramatically. IDC expects China to overtake the US this year and become the world's largest smartphone manufacturer. In this context, the competition among Chinese smartphone suppliers is very intense. The BCM43340 raises the bar for mass-market devices and provides OEMs with a cost-effective dual-band mobile device solution.
Although the mass market is expected to adopt the BCM43340, the BCM4335 provides a powerful solution for high-end smartphones. As the industry's first complete 5G WiFi mobile device combo chip, the BCM4335 takes the performance of the Chinese market to a new level, which increases the effective distance and throughput of Wi-Fi devices while reducing the battery's power consumption.
These chips also meet the growing demand for Wi-Fi offload in the Chinese market. With the dramatic increase in data usage on mobile devices, operators are looking for ways to mitigate the pressure on cellular networks. Broadcom's more robust wireless access and Wi-Fi offload capabilities enable operators to meet the challenges of this growing trend while continuing to provide customers with fast, reliable and seamless Internet access.
The first complete 5G WiFi combo chip for smartphones
5G WiFi is the 5th generation Wi-Fi based on the IEEE 802.11ac standard, which is a significant development based on the existing 802.11a/b/g/n network. 5G WiFi greatly extends the transmission distance of home wireless networks, enabling consumers to watch HD video in more places and through more devices at the same time. Compared to the use of similar 802.11n devices, the solution enables consumers to download web content and synchronize large files such as video in a very short time with a transfer speed of up to 3 times faster. 5G WiFi delivers the same amount of data faster, so the device can quickly enter a low-power mode with only one-sixth the power of the same 802.11n solution.
The new BCM4335 integrates a complete single-stream 5G WiFi system on a single silicon – including MAC (Media Access Control), PHY (Physical Layer) and RF (Radio Frequency), as well as Bluetooth 4.0, FM Radio and software. The platform-independent design of MAC, PHY, and RF allows the BCM4335 to be plugged into any smartphone or tablet platform, regardless of which application processor the platform uses. The Broadcom combo chip will set the industry's integration, performance and functionality with advanced wireless sleep coordination algorithms that mitigate wireless interference, advanced sleep modes that extend battery life, and the ability to offload large power tasks for the host processor. standard.
The BCM4335 chip introduces the latest version of Broadcom wireless coexistence technology. Mobile phone manufacturers can use this technology on 4G LTE cellular platforms to minimize the possibility of wireless interference between Wi-Fi operating at nearby radio frequencies, Bluetooth and LTE. Broadcom's global coexistence interface will support the Bluetooth Special Interest Group's LTE coexistence approach, which is compatible with 4G mobile phone modems from most vendors.

Cost-effective dual-band combination chip for mobile devices in the mass market in China
The BCM43340 features an integrated RF front end consisting of a single-shot (PA), low noise amplifier (LNA) and transmit/receive switch that significantly reduces the cost of implementing dual-band WiFi support in mobile devices. . Features such as Wi-Fi Direct and Wi-Fi CERTIFIED Miracast typically use the 5 GHz band, making dual-band operation a necessary feature for portable products. In addition, operating systems such as Android and Windows will support higher bandwidth multimedia applications on these devices, making the key to high-speed dual-band access increasingly critical.
43340 Product Highlights:
• The BCM43340 integrates Wi-Fi, Bluetooth and FM radio on a single chip;
• Advances in 40nm CMOS process technology and power management design reduce power consumption by 45%;
• Integration with PA, LNA and TR switches reduces size and BOM cost;
• Dual-band support provides a clean, interference-free network to meet the growing demand for IPTV and video browsing services over the wireless network in the Chinese market;
• Support for HT40 (high throughput 40MHz channel in the 5GHz band);
• Designed for low-cost PCB on-board applications.
Supply:
BCM43340 is currently sampling the early access customers of Broadcom, which is expected to be fully operational in the fourth quarter of 2012. The BCM4335 is also sampling for Broadcom's early access customers, which are expected to be fully operational in the first quarter of 2013.

Broadcom executives introduction:
Alex Chou, General Manager and Senior Director, China Communications, Broadcom Integrated Interconnects Division, Broadcom
“There are nearly 11 million IPTV subscribers in China, and this country is rapidly becoming the top consumer of ITPV services. As consumer groups turn to using mobile devices to watch video over Wi-Fi, the need for clean, interference-free wireless networks has become It's becoming more and more obvious. By supporting entry-level smartphones to work in the less-popular 5GHz band to provide a better and faster wireless experience, these latest solutions from Broadcom will meet this growing demand."
