This paper addresses the problem of coexistence between smart grid based wireless communication networks and other interfering signals. Particularly, the problem of interfering wireless local area network (WLAN) signals over smart utility networks (SUN) systems is analyzed. We develop a statistical model of the WLAN interferers, which is in turn used in predicting the capacity of SUN systems when affected by several WLAN interferers. Based on this analysis, a framework that promotes the application of an adaptive power control algorithm at the SUN transmitter is developed based on a Lagrangian optimization approach. Our proposed optimization approach involves solving a reduced-complexity algorithm which yields an optimal power allocation for each SUN packet. The results show that an adaptive power control approach results in a significant improvement of the SUN's network capacity when compared with fixed power transmissions.
