“Wi-Fi-based IPS rely on the strength of Wi-Fi signals and the triangulation method to locate devices. Limitation: They require a dense network of Wi-Fi access points for high accuracy, which can be costly and ineffective during power outages or in areas with signal interference.

Bluetooth Low Energy (BLE) Beacons use the proximity of devices to small, battery-powered wireless beacons. Limitation: Their accuracy diminishes with distance and can be affected by physical obstacles, requiring a significant number of beacons for comprehensive coverage.

Ultra-Wideband (UWB) Technology provides precise location tracking through time-of-flight measurement of radio pulses. Limitation: UWB requires the installation of specialised hardware and is relatively expensive, making it less feasible for large-scale deployments.

Radio-Frequency Identification (RFID) tracks the location of tags attached to objects or individuals. Limitation: RFID has limited range and requires line-of-sight for accurate tracking, making it less effective in complex building layouts.

Infrared (IR) Tracking Systems use IR sensors and emitters for location tracking. Limitation: Their functionality is severely limited by obstacles, as IR signals cannot penetrate walls, requiring an unobstructed line-of-sight.

Zigbee Wireless Networking is used to create personal area networks with small, low-power digital radios. Limitation: Similar to Wi-Fi and BLE, its effectiveness is dependent on the infrastructure’s density and can suffer from interference issues.

GPS Re-Radiating Systems amplify outdoor GPS signals indoors. Limitation: They are generally ineffective in deep indoor environments or lower levels of buildings where GPS signals are inherently weak or non-existent.

Acoustic Sound-Based Positioning Systems utilise sound waves to determine location. Limitation: Acoustic systems are sensitive to environmental noise and require a quiet environment for optimal accuracy, which is unrealistic in emergency situations.

Computer Vision and Facial Recognition Systems rely on cameras and image analysis to locate individuals. Limitation: These systems raise significant privacy concerns, require extensive camera coverage, and can be hindered by low visibility conditions.

Cellular-based location Tracking uses cell tower triangulation to estimate a device’s location. Limitation: Its accuracy is significantly reduced indoors due to signal attenuation by building materials and is not precise enough to pinpoint exact locations within buildings.

Why IndoorSOS Stands Out

IndoorSOS overcomes many of these limitations by leveraging existing emergency lighting infrastructure, ensuring operability even during power and internet outages. Its use of a real-time mesh network adaptability, AI for indoor mapping, and blockchain for secure data handling makes it robust against many challenges that other technologies face, such as signal interference, dependency on external power sources, and privacy concerns. Furthermore, its ability to function in extreme conditions without requiring the installation of specialised hardware or extensive infrastructure modifications gives it a significant edge in versatility and cost-effectiveness over the technologies listed above.

‘The quadrant diagram above visually compares various technologies for emergency location tracking against two key metrics: cost-effectiveness and operational reliability in emergencies, with an implied reference to IndoorSOS. Technologies like UWB Technology and BLE Beacons are highlighted for their operational reliability but may not be as cost-effective as others, such as Zigbee Networking or Cellular-Based Tracking, which offer greater cost-efficiency but with limitations in reliability during emergencies. IndoorSOS®️ is implied to surpass these technologies in both axes, signifying its superior operational reliability even in extreme conditions and its cost-effectiveness by leveraging existing infrastructure. This visual comparison underscores the unique advantages of IndoorSOS in providing a comprehensive and robust solution for emergency indoor location tracking.’ ​
