   Commercial asset tracking systems such as Apple AirTags use hundreds of millions of mobile devices as opportunistic data mules, enabling global location coverage without dedicated cellular infrastructure. However, existing trackers are limited to location reporting, rely on active BLE radios and coin-cell batteries, and cannot support long-term sensing deployments. We demonstrate SenseTag, a work-in-progress tracker that extends AirTag-like functionality towards battery-free, sticker form-factor sensing. SenseTag leverages Apple’s Find My network as a global backhaul for both location and sensor data, using backscatter communication to eliminate the cost of active BLE transmission. A key challenge is implementing Find My’s cryptographic protocol within the tag’s constrained compute and energy budget. Unlike prior systems that encode data into public BLE advertisement fields, exposing it to passive scanners, SenseTag embeds sensor readings into the private-key generation process, preserving Find My-compatible location decryption while preventing exposure to passive BLE scanners. We demonstrate an end-to-end prototype using commodity tag-side hardware and a controllable carrier emitter, backhauling environmental sensor data through Apple’s Find My network and visualizing recovered location and sensor readings on a web-based dashboard.

   Enabling Low-power Ubiquitous Connectivity for Embedded Systems through Audio-Broadcasting Tags

   ACM UbiComp ’25 Demo

   Abs DOI Bib PDF

   The challenges in wireless connectivity continue to hinder the widespread, scalable, and sustainable deployment of embedded systems. We introduce AudioCast to address the issues of spectrum scarcity-induced contention and high power consumption of transmitters. It leverages the availability of FM radio receivers operating within the 88–108 MHz spectrum, taking advantage of the superior radio-wave propagation characteristics afforded by lower-frequency bands. Specifically, AudioCast achieves at least a 10x reduction in path loss compared to the 2.4 GHz and 5 GHz ISM bands. This capability enables reliable long-distance communication while minimizing congestion and interference. AudioCast employs a single tunnel diode oscillator to generate carrier signals, which are then self-modulated with data encoded in baseband audio signals. This results in frequency-modulated transmissions that consume under 200 ?W of power, yet travel over 130 m in line-of-sight conditions. Unlike backscatter-based systems, AudioCast does not require an external carrier or depend on ambient signals, introducing a new category of transmitters termed Beyond-Backscatter transmitters, all while maintaining similar low power consumption.

   AudioCast: Enabling Ubiquitous Connectivity for Embedded Systems through Audio-broadcasting Low-power Tags

   Abs DOI Bib PDF Code

   Wireless connectivity challenges hinder the deployment of embedded systems. We introduce AudioCast to address two critical issues: spectrum scarcity-induced contention and high power consumption in transmitters. The widespread availability of broadcast radio receivers (for example, FM radios using the 88-108 MHz spectrum) and access to underutilized lower-frequency spectrum motivate the design of AudioCast. The lower-frequency spectrum offers superior radio-wave propagation characteristics, exhibiting at least 10x lower path loss than the 2.4 GHz and 5 GHz Industrial, Scientific, and Medical (ISM) bands while avoiding congestion and interference. These properties enable reliable and long-distance communication, even for weakly radiated signals. AudioCast builds on these properties and the unique negative resistance of a tunnel diode.AudioCast rethinks the architecture of radio transmitters using a tunnel diode oscillator to generate carrier signals and self-modulate them with baseband signals. This results in frequency-modulated transmissions at an overall power consumption below 200 μW. Unlike related systems based on the backscatter mechanism, AudioCast does not require an externally generated carrier or rely on ambient signals. We argue that AudioCast represents an example of a new class of transmitters which we conceptualize as Beyond-Backscatter transmitters. Through experiments, we demonstrate that AudioCast achieves a transmission range of up to 130 m in line-of-sight and tens of meters in non-line-of-sight conditions respectively. These transmissions are decodable by ubiquitous commodity FM receivers in cars, homes, and phones. We evaluate AudioCast through theoretical analysis, benchtop experiments, and urban/indoor field deployments. Additionally, we prototype and demonstrate novel applications, including low-power voice transmissions and hand gesture communication, enabled by AudioCast’s range and power efficiency.

   Light Fidelity utilizes light to enable high-bandwidth, low-interference networking and complements traditional radio-frequency links. We demonstrate that Light Fidelity’s precise spatial data confinement makes it a natural fit for mixed reality: By exploiting line-of-sight propagation with mixed-reality headset spatial awareness, we create "information spotlights" - which are localized optical zones that provide context-specific data, such as museum exhibit details or retail product information. This avoids radio frequency based localization, which is both computationally intensive and not supported in today’s commercial headsets. We present VisibleBits, a proof-of-concept Light Fidelity transceiver integrated with a Meta Quest 3 that converts optical signals into a visual serial protocol, overcoming hardware limitations. In our demo, users receive exhibit-specific real-time information, which is then overlaid onto their mixed reality headsets as they enter a Light Fidelity illumination zone.

   We have seen rapid deployment of augmented reality devices. However, these devices currently suffer from limited battery life. They require frequent recharge, especially when capturing and streaming information wirelessly. In particular, these devices stream information over the radio spectrum using transceivers that are power-hungry, and wireless communication dominates the energy budget of these devices. We present our ongoing work to design a system called Li-FiAR, which proposes integrating Li-Fi with augmented reality devices. Specifically, we implement a transmitter and receiver and integrate them with an augmented reality device. We argue that Li-Fi receivers may consume less power than their radio counterparts while benefiting from the spatial nature of light propagation. This enables novel application scenarios for augmented reality. We demonstrate the transmission of images and audio through Li-Fi, presented on an augmented reality device in this work.

   PixelGen: Rethinking Embedded Cameras for Mixed-Reality

   Abs DOI Bib PDF

   Mixed-reality headsets offer new ways to perceive our environment. They employ visible spectrum cameras to capture and display the environment on screens in front of the user’s eyes. However, these cameras lead to limitations. Firstly, they capture only a partial view of the environment. They are positioned to capture whatever is in front of the user, thus creating blind spots during complete immersion and failing to detect events outside the restricted field of view. Secondly, they capture only visible light fields, ignoring other fields like acoustics and radio that are also present in the environment. Finally, these power-hungry cameras rapidly deplete the mixed-reality headset’s battery. We introduce PixelGen to rethink embedded cameras for mixed-reality headsets. PixelGen proposes to decouple cameras from the mixed-reality headset and balance resolution and fidelity to minimize the power consumption. It employs low-resolution, monochrome image sensors and environmental sensors to capture the surroundings around the headset. This approach reduces the system’s communication bandwidth and power consumption. A transformer-based language and image model process this information to overcome resolution trade-offs, thus generating a higher-resolution representation of the environment. We present initial experiments that show PixelGen’s viability.

   Significant efforts to address the energy challenges of embedded systems have resulted in the design of new low-power transmitter architectures. These transmitters utilize backscatter or tunnel diode-based mechanisms to enable low-power transmissions by delegating energy-intensive tasks to external infrastructure. However, their widespread adoption is hindered by the need for specialized deployment setups, such as the precise placement of carrier-emitting devices. To overcome this, we are developing GateHaul-a low-cost gateway architecture that provides the required carrier signal, coordinates with other gateways, collects sensor data, and backhauls the information. Notably, GateHaul can backhaul sensor data without conventional networks utilizing emerging opportunistic backhaul networks. We demonstrate an early prototype of GateHaul that collects information from backscatter and conventional devices and backhauls the collected information using Apple’s FindMy network.

   Abs DOI Bib PDF

   Wireless embedded systems have seen rapid growth. Nonetheless, the further growth of these systems is now threatened due to the complexities of programming, networking, and deploying them. Developing embedded systems today is a challenging task primarily due to the vast diversity in radio standards, network stacks, microcontrollers, sensors, and other parts of the embedded system ecosystem. This complexity makes it a task suited only for experts, thus hindering the broader adoption of embedded systems.In this early work, we tackle a particular aspect of this challenge related to the complexities of wireless communication. Specifically, we explore the hypothesis that the emergent properties of large language models could help mitigate the complexities of programming the wireless communication stack. We adopt a complex radio transmitter design based on a backscatter mechanism and explore the generation of the transmitter’s logic using state-of-the-art language models. Our exploration leads to insights that, with appropriate prompting, today’s state-of-the-art large language models are already capable of generating complex modulation and backscatter logic. This finding warrants further efforts to design language model generated radio transmitters to simplify embedded systems.
