After exhaustive analysis, here are the key takeaways:
Beyond standard Wi-Fi, the act refines the technical parameters for Radio Frequency Identification (RFID) and Ultra-Wideband (UWB) systems. These technologies, increasingly found in automotive and industrial applications, now have clearer boundaries for emission limits, reducing the bureaucratic friction previously associated with cross-border technology imports.
