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.

This time, Haoran Technology passed the certified A55 bulb, using the exclusive light guide column and patented fin design, successfully broke the limitation of LED directional light source, and developed 360-degree full-circumference light, which can completely replace the traditional incandescent bulb LED bulb.
Hao Ran said that Haoran's LED bulbs, in addition to meeting the above specifications, have developed a power factor of up to 90%, surpassing the US Energy Star's 70% general standard, making energy use more efficient and complete, reducing power transmission. The process is inefficient and consumes the real energy saving and carbon reduction vision. 
Haoran Technology 360-degree full-angle LED light won the US "Energy Star" mark
Recently, Taiwan LED lighting manufacturer Haoran Technology developed a 360-degree full-angle LED bulb, becoming the first Taiwanese lighting manufacturer to receive the US government's energy subsidy through the US Energy Star logo.
