With both small-cell LTE and Wi-Fi networks available as alternatives for\ndeployment in unlicensed bands (notably 5 GHz), the investigation into their\ncoexistence is a topic of active interest, primarily driven by industry groups.\n3GPP has recently standardized LTE Licensed Assisted Access (LTE-LAA) that\nseeks to make LTE more co-existence friendly with Wi-Fi by incorporating\nsimilar sensing and back-off features. Nonetheless, the results presented by\nindustry groups offer little consensus on important issues like respective\nnetwork parameter settings that promote "fair access" as required by 3GPP.\nAnswers to such key system deployment aspects, in turn, require credible\nanalytical models, on which there has been little progress to date.\nAccordingly, in one of the first work of its kind, we develop a new framework\nfor estimating the throughput of Wi-Fi and LTE-LAA in coexistence scenarios via\nsuitable modifications to the celebrated Bianchi citeBianchi model. The\nimpact of various network parameters such as energy detection (ED) threshold on\nWi-Fi and LTE-LAA coexistence is explored as a byproduct and corroborated via a\nNational Instrument (NI) experimental testbed that validates the results for\nLTE-LAA access priority class 1 and 3.\n
