The PufangTech`s wireless data modem is used to replace standard RS232 and RS485 serial communication cables. It provides a transparent connection between source and destination terminal and requires no knowledge of the data it is transmitting and the data can be simply sent and received with minimal delay.
With 12.5KHz channel spacing, the over-air transmission adopts different modulation scheme to meet various air rates. For air rate below 1200 bps, modulation scheme of FSK is used. For air rate of 1200, 2400 or 4800bps, MSK or FFSK modulation scheme is used. At 8000bps air rate, GMSK modulation scheme is adopted and at 9600bps air rate, the modulation is 4-level FSK. With 25KHz channel spacing, GMSK modulation scheme can support air rate of 16000bps and 4-level FSK can support 19200bps.
PufangTech`s wireless modem can make very beneficial and value added agreements with distributors and system integrators.

Previously, Delft University of Technology had established four research centers in China. According to Beenakker, director of the Research Center of Delft University of Technology in China, LED is a green energy-saving lighting. Both China and the Netherlands are at the forefront of LED technology research. The cooperation between the two sides can be mutually beneficial and win-win.
Beenakker believes that the Dutch cooperation in China has enabled it to acquire knowledge, high-tech talent and funds. The China office in Delft will help China better develop and establish contacts with European investors. The Delft office is the first branch of the China National Key Laboratory to be established overseas. The choice of Delft is due to the existing cooperation between the two parties and the excellent innovation environment in the Netherlands. 
China set up an office in the Netherlands to focus on LED technology
Recently, China National Key Laboratory opened an office in Delft University of Technology in the Netherlands, focusing on solid-state lighting (LED lighting) technology. The office is currently actively raising funds to support research related to LED lighting.
