Potential transmission capability of wireless communication network

It has long been accepted that Shannon capacity is the channel transmission capability limit, but this is a misunderstanding. This paper considers the actual communication system bandwidth is limited, and the band limited Gauss noise (BLGN) has correlation, which leads to the actual entropy of BLGN is smaller than its maximum entropy, so the actual channel capacity is always greater than the Shannon capacity, although the noise is AWGN. We derived the formula of BLGN correlation coefficient between adjacent timeslots, calculated the numerical solution β ≈ 0.167. The testing results indicate that man-made noise in the wireless channel has become a major noise, and its power is much greater than the natural noise power. In addition the man-made noise has a strong correlation. This makes the wireless channel capacity is clearly greater than the Shannon capacity. Therefore the current wireless channel has a large potential transmission capability.
