Underwater 3D positioning on smart devices
Tuochao Chen, Justin Chan, Shyamnath Gollakota
The emergence of water-proof mobile and wearable devices (e.g., Garmin Descent and Apple Watch Ultra) designed for underwater activities like professional scuba diving, opens up op…
Underwater Acoustic Ranging Between Smartphones
Tuochao Chen, Justin Chan, Shyamnath Gollakota
We present a novel underwater system that can perform acoustic ranging between commodity smartphones. To achieve this, we design a real-time underwater ranging protocol that comput…
Underwater Messaging Using Mobile Devices
Tuochao Chen, Justin Chan, Shyamnath Gollakota
Since its inception, underwater digital acoustic communication has required custom hardware that neither has the economies of scale nor is pervasive. We present the first acoustic…
DeepSense: Enabling Carrier Sense in Low-Power Wide Area Networks Using Deep Learning
Justin Chan, Anran Wang, Arvind Krishnamurthy +1
The last few years have seen the proliferation of low-power wide area networks like LoRa, Sigfox and 802.11ah, each of which use a different and sometimes proprietary coding and mo…
Surface MIMO: Using Conductive Surfaces For MIMO Between Small Devices
Justin Chan, Anran Wang, Vikram Iyer +1
As connected devices continue to decrease in size, we explore the idea of leveraging everyday surfaces such as tabletops and walls to augment the wireless capabilities of devices.…
