Providing Accurate Indoor Emergency Locations For Rapid Emergency Response and Resilience.

Our Mission. Find people in emergencies indoors promptly by harnessing the building facilities’ IOT data of actionable indoor emergency locations to support incident and emergency response.

Why? Emergency service agencies have struggled to find distressed callers inside multi-level buildings for far too long. “Section 506 of the Ray Baum’s Act requires that the FCC consider adopting rules to ensure dispatchable location’ information is conveyed with 911 calls, regardless of the technology used, so that PSAPs will receive the caller’s location automatically and can dispatch responders quickly and accurately locate the caller. Dispatchable location information includes the caller’s street address and additional information, such as a room or floor number, or similar information necessary to adequately identify the calling party’s location as quickly as possible.”

FCC has issued the forward-looking mandates.

From April 3, 2021, with a six-year benchmark.

  • …….CMRS providers also must deliver z-axis information to meet the accuracy metric of within 3 meters above or below (plus or minus 3 meters) the handset in Height Above Ellipsoid and floor level information where available  (47 CFR § 9.10(i)(2)(ii)(C)

From January 6, 2022,

  • All CMRS providers shall provide the dispatchable location with wireless E911 calls if it is technically feasible for them to do so (47 CFR § 9.10(i)(2)(ii)(G)))

To achieve floor-level accuracy at any time poses a significant challenge. The wireless industry has invested heavily in complying with the z-axis +/- 3 meters standard. However, such efforts do not warrant precise floor-level information. The ‘Automated 911 Dispatchable Locations’ as required by Ray Baum’s Act pose significant challenges, especially in power outages.

Power outages are more frequent than many would have thought, caused by faults in underground cable and distribution systems, short circuits in equipment, natural disasters and human errors, planned distribution network maintenance, and the firefighters’ MPO practices that cut off local power supply in response to in-building emergencies and the ‘Public Safety Power Shutoff-PSPS’ that turn off the power in the specific areas. Rolling blackouts accompany extreme weather conditions when demand exceeds the power supply capacity. Other disasters, such as heavy storms, earthquakes and flooding, may worsen the circumstances. 

There is a need for a reliable indoor position system that is always up for action to provide 911 call dispatchable locations of floor level and room numbers.
IndoorSOS® is committed to solving this problem.

A Technological Paradigm. 

We live in an increasingly wireless world, especially inside buildings, where we spend over 80% of our lifetime. The influx of Internet of Things (IoT) devices and systems has started a new wireless era in our living environment, typically indoors. This in-building wireless RF technological paradigm creates an omnipresent opportunity to apply indoor positioning technologies to help locate emergency callers.  
Smart building facilities/utilities, such as smart lighting, access control, smoke alarms &, etc., are embedded with sensors/microcontrollers permanently deployed in the buildings. They transmit data packets under specific radio frequency communication protocols, which are also adopted by smartphones and wearables. These wireless sensors have unique electronic IDs and addresses to communicate with each other and connect to the internet under specific networking topologies. On calling 911, smartphones and wearables can interact with these facilities. They can identify their indoor positions by computing the groups of clustered and indexed unique IDs and RF communication addresses of these sensor nodes.   Therefore, the communication triggered by the emergency call can reveal the caller’s location relevant to these nodes’ physical location address, including the floor level and room number. Proudly, IndoorSoS™ has developed a cloud computing and mapping engine assisted by a machine-learning algorithm to empower these sensor nodes to act as ever-ready ‘satellites’ to locate emergency calls inside the buildings.

IndoorSOS® is a cutting-edge solution for indoor locations with certainty.

IndoorSoS® Automatic Dispatchable Location ( ADL) is a cloud-native platform of Digitised Civic Addresses based on lighting facilities with AI indoor mapping and positioning programs. It features a public blockchain of lighting IDs to facilitate installing and deploying smart lighting products inside buildings on an authoritative GIS indoor map. Its patented backbone lighting system powers the embedded sensors to support indoor emergency location/position/detection and communications, including during power cuts. 

The backbone lighting network may be connected to the internet through dedicated wireless access, such as the FirstNet™. The groups of clustered unique IDs of the permanent facilities, such as the smart emergency lights, are indexed, referenced & tagged to the data source of the physical areas of room number and floor level, forming a digital twin of a critical database of the Emergency addresses. The digital twin cloud program collects and processes real-time synchronised data from the embedded sensors/controllers that interact with the caller’s handset in response to emergency calls. A machine learning algorithm manoeuvres the datasets and continually gains knowledge of the facilities’ dynamics data for physical emergency caller location enhancement. The emergency caller’s real-time location data are compiled into an Emergency Incident Data Document (EIDD) compliant with Next Generation 9-1-1 standards and shared with the emergency call centre dispatchers and field responders over the Emergency Service Internet (Esinet).
