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.
