Communication by means of Modulated Johnson Noise
Zerina Kapetanovic, Miguel Morales, Joshua R. Smith
We present the design of a new passive wireless communication system that does not rely on ambient or generated RF sources. Instead, we exploit the Johnson (thermal) noise generate…
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…
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…
BLISP: Enhancing Backscatter Radio with Active Radio for Computational RFIDs
Ivar in 't Veen, Qingzhi Liu, Przemysław Pawełczak +2
We demonstrate the world's first hybrid radio platform which combines the strengths of active radio (long range and robustness to interference) and Computational RFIDs (low power c…
Wisent: Robust Downstream Communication and Storage for Computational RFIDs
Jethro Tan, Przemysław Pawełczak, Aaron Parks +1
Computational RFID (CRFID) devices are emerging platforms that can enable perennial computation and sensing by eliminating the need for batteries. Although much research has been d…
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…
