Work from home for techies, online classes for students, games for kids, webinar for teaching fraternity etc., are going almost on indoor coverage without any limit in pace because of the smart spectrum coverage by the network service providers. This paper provides an add-on facility to the existing wireless infrastructure to provide a better user experience in this highly regrettable routine. In this paper, a cognitive domain unused spectrum holes are efficiently handled by (i) adaptive spectrum management technique; (ii) Fuzzy Inference System based spectrum administration and (iii) Hybrid Cognitive Femtocell approaches based on the user demand and their applications. The proposed integrated cognitive femtocell and Fuzzy-based approach reduces the indoor coverage problems and enhances the throughput of the macrocell users by allowing adaptive spectrum management based on the demand, thereby eliminating spectrum underlay and overlay problems during critical conditions. In cognitive femtocell networks, the access points are prepared and installed with Cognitive Radio which can determine spectrum dynamically by macrocells and nearby Femto Access Points. It adjusts its radiating parameters to evade the macrocells\u2019 interferences and the neighbouring femtocells, thereby maximising the spectrum band\u2019s overall utility.<\/jats:p>","DOI":"10.3233\/jifs-202540","type":"journal-article","created":{"date-parts":[[2021,8,31]],"date-time":"2021-08-31T14:14:54Z","timestamp":1630419294000},"page":"6079-6088","source":"Crossref","is-referenced-by-count":0,"title":["Hybrid
