1. 16. Backscatter Communications for 6G

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
   Keywords : Technology and Engineering;

   Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.
