Integrating the various embedded devices and systems in our environment enables an
Internet of Things (IoT) for a smart city. The IoT will generate tremendous amount of data that …

Backscatter communication (BackCom) networks enable passive/battery-free Internet-of-
Thing devices, providing reliable, massive connectivity while ensuring self-sustainability, low …

The vision of embedding connectivity into billions of everyday objects runs into the reality of
existing communication technologies--there is no existing wireless technology that can …

This paper presents PLoRa, an ambient backscatter design that enables long-range
wireless connectivity for batteryless IoT devices. PLoRa takes ambient LoRa transmissions …

We present HitchHike, a low power backscatter system that can be deployed entirely using
commodity WiFi infrastructure. With HitchHike, a low power tag reflects existing 802.11 b …

As the Internet of Things (IoT) advances by leaps and bounds, a multitude of devices are
becoming interconnected, marking the onset of an era where everything is connected. While …

We present the first wireless protocol that scales to hundreds of concurrent transmissions
from backscatter devices. Our key innovation is a distributed coding mechanism that works …

In this paper, we look at making backscatter practical for ultra-low power on-body sensors by
leveraging radios on existing smartphones and wearables (eg WiFi and Bluetooth). The …

LoRa has emerged as a promising Low-Power Wide Area Network (LP-WAN) technology to
connect a huge number of Internet-of-Things (IoT) devices. The dense deployment and an …

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 a …
