On the afternoon of September 27, I met my Tsinghua classmate Dr. Zhang Gang at the Shenzhen Exhibition Center.
He developed theBluetooth 5.0 chip,the first domestic mass-produced,low-power Bluetooth 5.0 chip, with a transmission distance of up to 300 meters, a transmission rate doubled, and power consumption reduced by three times.
1. Comes from a prestigious background. After graduating from Tsinghua, Zhang worked at Qualcomm in the U.S. for over a decade, focusing on mobile chip design, leading a team that obtained multiple patents. He resolutely returned to China to start a business two years ago, successfully developing a new Bluetooth chip with leading intellectual property.
2. Technology is unparalleled globally.The technical fields are primarily categorized into power consumption, transmission distance, and sensitivity.
The low-power technology is unparalleled globally. It reduces power consumption by three times compared to current Bluetooth chips, allowing BEACON Bluetooth devices to last four years on a button battery without replacement!
Its transmission distance and rate are also several times greater than current Bluetooth. Currently, Bluetooth ranges only 5 to 10 meters, but it can reach 300 to 500 meters. Its cost is more than twice lower than imported chips.
Overall, Bluetooth chip 5.0 surpasses major European and American manufacturers, enough to spark a Bluetooth revolution.
3. Seizing the opportunity.The new chip supports MESH solutions (hailed as the “next-generation internet”), supportingthousands of nodes for self-organization! This technology makes signal transmission safer and faster, expanding the application of Bluetooth technology from the consumer sector to the industrial manufacturing sector, evolving from the traditional “one-to-many” to “many-to-many” (disrupting your understanding of Bluetooth), achieving “decentralization.”
4. Achieving a “wireless IoT.” Zhang stated that next year he will launch a low-power Bluetooth and narrowband NBIoT dual-mode chip. This dual-mode chip technology can achieve full coverage of local and wide-area “wireless IoT” by using Bluetooth indoors and telecom narrowband outdoors.
5. Strong alliances create great achievements. The circuit board exhibited today represents the technical cooperation of two Tsinghua 89 classmates: the Bluetooth chip is from Zhang’s company, and the memory chip sealed next to it is from Zhaoyi Innovation’s Zhu, fulfilling Tsinghua University’s ideal of replacing imports.
6. Capital market’s keen interest! With such advanced technology and a vast market (currently, 8 billion Bluetooth products are in use), many investment institutions are negotiating for the second round of financing.
Here’s wishing my old classmate’s team success in the national chip strategy development trend, forging ahead with pride…
