3rd Party Hardware and Software used
- Lime microsystems SDR
PoC developed, outstanding issues being addressed:
- Misalignment between the Rx channels
- Gain mismatch or gain changes randomly
- Firmware loading problems
Disasters always strikes in people lives and can be hard to predict. Every disaster leaves behind casualties and injured people. Visual and even thermal detection can easily miss people.
LimeSDR can be used to augment these systems with wireless-based victim detection. This could significantly reduce the exploration time needed to locate victims due to the following reasons:
- Unlike conventional robotics sensor which cannot operate in occluded situation like wall, wireless sensor still operate as the signal can propagate through obstacles
- LimeSDR supports a wide frequency spectrum range which could be used to detect multiple signals emitted from the phone for enhanced detection
...so leading to lower mortality rates.
Wireless Detection is based on identifying 802.11a Legacy signal which could be transmitted from the victim phone. This signal can be detected by estimating:
- RSSI (Received Signal Strength Indication)
- DOA (Direction of arrival)
