Right after the base specification was published, several voices rose up in the working group advocating to broaden the scope of IEEE 802.21 beyond handovers. This paper aims at updating the reader with the main challenges and functionalities required to create a Media Independence Service Layer, through the analysis of scenarios which are being discussed within the working group: 1) Wireless Coexistence, and 2) Heterogeneous Wireless Multihop Backhaul Networks.", comments = "JCR 2011 Q2 1.257, SJR 2011 Q2 0.55, Scopus 2011 Q1 4.2", doi = "10.1016/j.csi.2011.03.001", impact_factor = "1.257", issn = "0920-5489", journal = "Elsevier Computer Standards {\&} Interfaces", keywords = "Media independence;IEEE 802_21;Wireless Coexistence;Heterogeneous mesh networks", month = "November", number = "6", pages = "556-564", title = "{IEEE} 802.21: {M}edia independence beyond handover", volume = "33", year = "2011", }
