This article introduces a dual-mode backscatter integrated circuit that supports both WiFi and Bluetooth low-energy (BLE) transmissions. It enables a multiantenna WiFi mode with reconfigurable beam steering of single-sideband (SSB) quadrature phase shift-keying (QPSK) signals. while also facilitating omnidirectional SSB BLE-to-BLE backscatter communication. To achieve beam steering. https://www.marcelovicente.com/product-category/spray-wax/
