Simplifying Backscatter Deployment: Full-Duplex LoRa Backscatter
Mohamad Katanbaf, Anthony Weinand, Vamsi Talla
Due to the practical challenges in the deployment of existing half-duplex systems, the promise of ubiquitous backscatter connectivity has eluded us. To address this, we design the…
Advances and Open Problems in Backscatter Networking
Vamsi Talla, Joshua Smith, Shyamnath Gollakota
Despite significant research in backscatter communication over the past decade, key technical open problems remain under-explored. Here, we first systematically lay out the design…
Wireless Quantization Index Modulation: Enabling Communication Through Existing Signals
Zerina Kapetanovic, Vamsi Talla, Aaron Parks +2
As the number of IoT devices continue to exponentially increase and saturate the wireless spectrum, there is a dire need for additional spectrum to support large networks of wirele…
Ultra-low-power Wireless Streaming Cameras
Saman Naderiparizi, Mehrdad Hessar, Vamsi Talla +2
Wireless video streaming has traditionally been considered an extremely power-hungry operation. Existing approaches optimize the camera and communication modules individually to mi…
LoRa Backscatter: Enabling The Vision of Ubiquitous Connectivity
Vamsi Talla, Mehrdad Hessar, Bryce Kellogg +3
The vision of embedding connectivity into billions of everyday objects runs into the reality of existing communication technologies --- there is no existing wireless technology tha…
FM Backscatter: Enabling Connected Cities and Smart Fabrics
Anran Wang, Vikram Iyer, Vamsi Talla +2
This paper enables connectivity on everyday objects by transforming them into FM radio stations. To do this, we show for the first time that ambient FM radio signals can be used as…
Inter-Technology Backscatter: Towards Internet Connectivity for Implanted Devices
Vikram Iyer, Vamsi Talla, Bryce Kellogg +2
We introduce inter-technology backscatter, a novel approach that transforms wireless transmissions from one technology to another, on the air. Specifically, we show for the first t…
Powering the Next Billion Devices with Wi-Fi
Vamsi Talla, Bryce Kellogg, Benjamin Ransford +3
We present the first power over Wi-Fi system that delivers power and works with existing Wi-Fi chipsets. Specifically, we show that a ubiquitous piece of wireless communication inf…
