An Evaluation of Wi-Fi 802.11b Backscatter

Internet of Things (IoT) devices are in need of low-power communications systems with longevity and reliability. With the use of backscatter technology, IoT devices can communicate at the cost of almost no power and can last for up to a decade. Furthermore, backscatter technology is compatible with everyday wireless signals such as Wi-Fi and Bluetooth, allowing for easy communication without specific hardware constraints. This thesis aims to evaluate a Wi-Fi backscatter system and analyze its ease in triggering off of such ambient signals and sources. The system will utilize Wi-Fi 802.11b as a backscatter source to trigger the backscatter system to transmit its own data as a modified Wi-Fi signal 802.11b. This thesis will establish the effectiveness of a particular backscatter implementation, provide an overview of its systems, and demonstrate the efficacy of each system’s abilities
