The use of retrodirective tags is inevitable for a complete and reliable integration of next-generation RFID tags and Internet-of-things (IoT) sensors with future generation of wireless technologies such as mm-wave and massive multiple-input multiple-output (MIMO) communications. The benefits of using retrodirective tags are summarized in three major points: First, since retrodirective tags that operate at microwave and mm-wave frequencies have similar propagation properties\u0026mdash;in terms of power losses and field-of-view\u0026mdash;to the current RFID tags, which operate at ultra-high frequency (UHF) band, high-frequency retrodirective tags maintain the same coverage distance as the UHF tags and permit faster data rate because of the spectrum availability at microwave and mm-wave regimes. Second, retrodirective tags reduce the randomness of the backscatter RFID channel by changing the small-scale statistical behavior of the channel from\u0026nbsp; double- to single-fading statistics, much like current wireless channels. Third, by sharing some of the spectral bands with future wireless technologies, retrodirective tags would enable fast, compact, and complete wireless connectivity.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Theory and Design of Next-generation Retrodirective Tags and Their Channels"}],"uid":"28475","created_gmt":"2018-04-12 20:44:13","changed_gmt":"2018-04-12 20:44:13","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-04-18T16:00:00-04:00","event_time_end":"2018-04-18T18:00:00-04:00","event_time_end_last":"2018-04-18T18:00:00-04:00","gmt_time_start":"2018-04-18 20:00:00","gmt_time_end":"2018-04-18 22:00:00","gmt_time_end_last":"2018-04-18 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
