According to the data of ABI Research, in 2019, the number of smartphones will reach 5.6 billion! The use of video and other content, the main mobile data flow will be more than 10 times, and the mobile data traffic growth rate exceeds the number of users growth, which is beneficial to the increase in mobile network speed and the number of users. Among them, the upgrade of terminal network speed will play a great promotion.
Bo Tong BCM4358 chip combines 5G WiFi 2x2 mimo chip, combined with two 802.11ac data streams within 80MHz channel bandwidth through the PCIe interface, achieving up to 650Mbps data transmission capabilities, and upgrading a 50% performance Bluetooth chip while optimizing WiFi and Bluetooth coexistence performance. Users can download the content, less buffer time to view the video, and can simultaneously connect multiple Wi-Fi and Bluetooth devices (eg, listening to music and playing games simultaneously) and each device does not interfere with each other. In addition, due to the increase in positioning accuracy to one meter, the implementation of new and optimized indoor positioning services is possible.
In addition to the speed increase, this chip uses an indoor positioning system based on high-precision round-trip time RTT to achieve positioning ability of accuracy to one meter distance, making services in indoor environments. At the same time, this chip also solves multi-RF interference issues and system compatibility issues (compatible with Android, Windows, and Chrome systems). Of course, the new chip has better power consumption capabilities while performance improvement, allowing mobile terminals to achieve higher battery life.

Industry evaluation
"5G WiFi and 2X2 MIMO combination makes the potential of today's smartphones and tablets, which has become a must-have requirement for high-end mobile devices for wireless connections." David Recker, senior director of Boyong Company, said, " BCM4358, we have solved the serious multi-RF interference problem, which has established a higher standard for its performance. This fully reflects the commitment of Bo Tong: Committed to the first to launch a functional solution in the market. "
"Broadong is the first manufacturer of 2x2 mimo combination chips for smartphones, and still working hard to promote 802.11ac in all electronic consumer industry applications," said Philip Solis, ABI Research Research, said, "This second-generation innovation Technology shows the absolute leadership of Bo Tong's continued 2X2 MIMO technology. "
Time to market:
BCM4358 has been put into production, and the related mobile devices adopted by this chip will be available in the third quarter of 2014.
