In wireless communication, using overlapping frequency channels is a prevalent cause of interference. This interference occurs because wireless signals on the same or closely overlapping frequencies can disrupt each other, leading to significant degradation in network performance. The selection of non-standard antennas, while impactful in signal propagation, doesn't directly relate to the interference between signals. Incorrect subnet masks affect network addressing but not signal interference. Setting high transmission power can cause interference with other devices but is less likely to be a direct issue than overlapping frequency channels.
