First, implement <strong>equipment shielding<\/strong> \u548c <strong>signal isolation techniques<\/strong> to protect sensitive network components from RF emissions generated by machinery. Second, <strong>optimize transmit power settings<\/strong> to maintain sufficient coverage while minimizing unnecessary signal propagation that contributes to interference.<\/p>\n<p>Third, <strong>migrate away<\/strong> from legacy devices operating in the 2.4GHz band toward 5GHz or 6GHz equipment, which provides access to wider channels with reduced congestion.
