The know-how, known as ‘UbiqMap’, leverages radio frequency-based imaging to create detailed maps of indoor environments utilizing a method known as ‘Radio Tomographic Imaging’ or RTI, IIT Madras knowledgeable.
As identified by IIT Madras, the RTI techniques historically depend on a community of wi-fi transceivers deployed at mounted, recognized areas. As these transceivers talk, the wi-fi sign energy weakens when obstructed by constructions. This discount in sign energy is analyzed to reconstruct the structural structure or ground map of the realm.

UbiqMap removes this dependency on pre-installed infrastructure, and employs wearable transceivers that may be simply worn by rescue personnel.
As group members transfer by means of the surroundings, these units routinely decide their positions and constantly replace the ground map, offering an correct and real-time structure of the realm.
UbiqMap may also be successfully mixed with state-of-the-art SLAM (Simultaneous Localization and Mapping) methods to boost efficiency additional.

First responders achieve entry to correct, up-to-date maps of indoor areas, even in low-visibility or partially accessible environments, empowering them to plan evacuation routes and allocate sources extra successfully, as per IIT Madras.
Notably, this know-how is predicted to be useful for first responders throughout catastrophe reduction operations as conventional infrastructure usually turns into inaccessible or unreliable throughout public security emergencies.
Moreover, UbiqMap additionally has the potential to develop into a foundational know-how for good cities and autonomous techniques, enabling superior mapping operations in advanced indoor environments.

It could be talked about right here that the analysis on UbiqMap was led by Dr. Ayon Chakraborty, Assistant Professor, Division of Laptop Science and Engineering at IIT Madras. Dr Chakraborty’s group consists of Amartya Basu, MS Scholar at IIT Madras, and Kush Jajal, M.Tech Scholar at IIT MAdras.
The analysis group has additionally filed for an Indian Patent for this know-how. The work has additionally been revealed within the reputed, peer-reviewed journal IEEE Transactions on Cellular Computing (DOI: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10634790)
Dr. Ayon Chakraborty, elaborated on this know-how, and stated that public security incidents, significantly search and rescue operations, are sometimes hindered by lack of correct and up-to-date indoor constructing plans.
“Even when maps are available, they typically fail to capture real-time dynamics essential for effective mission planning during disasters. Our technology offers first responders a robust and portable tool to image indoor environments without dependence on visual line of sight or extensive computational resources, making it an invaluable asset in complex, time-critical scenarios,” highlighted Dr. Chakraborty.
Shedding mild on the present standing of the know-how and a tentative timeline for subject implementation, Dr. Chakraborty stated, “We have successfully tested the technology in a controlled setup within a few residential units at IITM campus. These trials allowed us to validate the system’s functionality, though the movement and localization of the transceivers were carefully managed during the tests.”
He added, “An important ongoing focus is optimizing the choice of wireless frequency. This involves balancing better indoor penetration with higher imaging resolution—an essential tradeoff in the design of wireless sensing systems. Additionally, we are integrating UbiqMap with visual modalities using sensor fusion. Currently, we are in the process of prototyping a wearable version of the technology to prepare for field trials in real-world scenarios.”
