Many kinds of multi-purpose wireless communication chips exist. However, their transmission power, throughput and error correction schemes are fixed. It is hard to apply them to various wireless applications with various quality-of-service. However, bit error occurs frequently in that transmission speed, which results in corrupted digital image when we use the chip module for image transmission. Unfortunately, this chip module does not have any error correction functionality. Hence, transmission speed should be reduced for reliable wireless data transmission. In this paper, a channel coding scheme is adopted outside of the chip module. Especially, the convolutional code is adopted as an error correction code. When the channel coding is adopted, frame error probability is analyzed considering practical chip setup parameters. By using the channel coding added outside of the chip module, reliable image transmission becomes available. Using multiple chip modules and channel coding together, throughput enhancement with trusted wireless transmission can be implemented.
