Bilişsel radyo ağları (Cognitive Radio Networks, CRNs) kullanılarak güvenilir bir spektrum elde edebilmek günümüz kablosuz iletişim teknolojileri ve Nesnelerin İnterneti (Internet of Things, IoTs) uygulamaları için vazgeçilmez olmuştur. Bu çalışmada, CRN’ler için spektrum algılama yaklaşımında yeni eğilimler incelenmiştir. Düşük güçlü geniş alan ağları (Low Power Wide Area Networks, LPWANs) standartlarından biri olan geniş kapsama (Long Range, LoRa) içerikli CRN’ler ile spektrum algılaması yapılmıştır. Burada amaçlanan, kullanıcıların frekans spektrumlarından maksimum oranda faydalanabilmesini sağlayabilmektir. Daha hassas spektrum algılaması sayesinde haberleşmedeki farklı bant genişliği ve sinyal yayılım faktörlerine bağlı olarak bant genişliği kullanımı verimli hale getirilmiştir. Buna paralel olarak, bant genişliğinde kullanılan miktar artırılarak verimli güç/frekans analizi yapılmıştır.
