However, the advent of LTE unlicensed technologies has raised serious concerns on Wi-Fi networks that are operating in the same bands. In this work, we evaluate LTE\/Wi-Fi coexistence, by conducting experiments with commodity LTE unlicensed and state-of-the-art 802.11ac Wi-Fi testbeds. Our experimental results show that LTE-induced interference not only can decrease Wi-Fi throughput by an order of magnitude, but also significantly impact the operation of 802.11ac high-throughput features (MU-MIMO, channel bonding, rate adaptation). To this end, we design LTERadar, a lightweight interference detector that runs on Wi-Fi devices and accurately detects LTE interference. LTERadar is independent of the technology of LTE interferer (LTE-U or LAA, the dominant LTE unlicensed protocols). Our implementation and evaluation with off-the-shelf Wi-Fi APs show LTERadar's interference detection accuracy to be more than 90% in realistic settings. We corroborate the 90% accuracy of LTERadar out in the wild, under dense enterprise Wi-Fi environments.<\/jats:p>","DOI":"10.1145\/3224428","type":"journal-article","created":{"date-parts":[[2018,6,13]],"date-time":"2018-06-13T18:21:15Z","timestamp":1528914075000},"page":"1-31","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["LTERadar"],"prefix":"10.1145","volume":"2","author":[{"given":"Christina","family":"Vlachou","sequence":"first","affiliation":[{"name":"Hewlett Packard Labs, Palo Alto, CA, USA"}]},{"given":"Ioannis","family":"Pefkianakis","sequence":"additional","affiliation":[{"name":"Hewlett Packard Labs, Palo Alto, CA, USA"}]},{"given":"Kyu-Han","family":"Kim","sequence":"additional","affiliation":[{"name":"Hewlett Packard Labs, Palo Alto, CA, USA"}]}],"member":"320","published-online":{"date-parts":[[2018,6,13]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"http:\/\/www.etsi.org\/deliver\/etsi_en\/301800_301899\/301893\/02.00.07_20\/en_301893v020007a.pdf. {Online","author":"GPP","year":"2018","unstructured":"3 GPP Release 13. http:\/\/www.etsi.org\/deliver\/etsi_en\/301800_301899\/301893\/02.00.07_20\/en_301893v020007a.pdf. {Online ; accessed 2018 \/05\/29}. 3GPP Release 13. http:\/\/www.etsi.org\/deliver\/etsi_en\/301800_301899\/301893\/02.00.07_20\/en_301893v020007a.pdf. {Online; accessed 2018\/05\/29}."},{"key":"e_1_2_1_2_1","volume-title":"https:\/\/portal.3gpp.org\/desktopmodules\/\\Specifications\/SpecificationDetails.aspx'specificationId=2579. {Online","author":"GPP","year":"2018","unstructured":"3 GPP Release 13, Evaluation. https:\/\/portal.3gpp.org\/desktopmodules\/\\Specifications\/SpecificationDetails.aspx'specificationId=2579. {Online ; accessed 2018 \/05\/29}. 3GPP Release 13, Evaluation. https:\/\/portal.3gpp.org\/desktopmodules\/\\Specifications\/SpecificationDetails.aspx'specificationId=2579. {Online; accessed 2018\/05\/29}."},{"key":"e_1_2_1_3_1","volume-title":"https:\/\/wireless.wiki.kernel.org. {Online","author":"Minstrel Rate Adaptation Atheros","year":"2018","unstructured":"Atheros - Minstrel Rate Adaptation . https:\/\/wireless.wiki.kernel.org. {Online ; accessed 2018 \/05\/29}.
