摘要: Detecting a leak of an OFDM signal (1900) from HFC network (103), where the (103) extends over area (105s, collectively). The includes first continuous pilot subcarrier (1800) having harmonic (2401). is defined by pre-determined frequency (2404). method or apparatus comprises steps means for: (a) moving leakage detector (102) through (105s); (b) tuning to receive (2401) signal, based on (2404) (2401); (c) with (102), receiving over-the-air, at received (2404), leaked (103); and (d) detecting in step (c), whereby detected detection
