The apparatus comprises an energy detection unit configured to measure receive energy over a first bandwidth and a second energy detection unit configured to measure receive energy over a second bandwidth. The apparatus further comprises a processor configured to compare the measured receive energy over the first bandwidth to a first energy threshold, to compare the measured receive energy over the second bandwidth to a second energy threshold, and to detect the presence of the frequency channel when the measured receive energies over the first and second bandwidths are above the first and second energy thresholds, respectively."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhanced channel detection","description":"An apparatus for detecting the presence of a frequency channel is provided.
