![]() ![]() In contrast, WiFi Sensing accurately detects movement (including falls) from anywhere within the monitored environment – no matter how close a person is to the device. When using radar technology for fall detection, someone would have to fall in front of the device for it to successfully detect the fall. This becomes especially problematic in healthcare and elderly monitoring settings. WiFi is ubiquitous in our modern age, and WiFi Sensing can provide presence detection coverage anywhere equipped with WiFi – a home, a building, a car, etc.Īdditionally, radar’s coverage is in a “cone” shape – the highest level of accuracy is closest to the device, decreasing the farther away you get. WiFi Sensing has far fewer (if any) blind spots, increasing scope of coverage. Though this is fine in select applications, it means that the technology’s capabilities are limited by frequent blind spots. Radar technology is line-of-sight, meaning it can’t see through walls or wrap around corners to cover multiple rooms. What makes them different? How do they stack up against each other? Read on for a full comparison. ![]() Though radar and WiFi Sensing are similar, they are not the same. In the future, it will replace the use of radar in certain environments. WiFi Sensing uses existing WiFi waves to detect and analyze movement. Ray Liu, has worked on radar projects and first encountered the potential of WiFi when solving multipath issues within a submarine for Defense Advanced Research Projects Agency (DARPA). The inventor of WiFi Sensing, Origin CEO Dr. However, in recent years, engineers have developed technology that distinguishes itself from radar: WiFi Sensing. Originally developed for military use during World War II, the applications of radar technology have expanded dramatically over time – you can now find radar used in modern vehicles, in train tunnels, in mining, and in traffic monitoring. Radar has been used by governments and technology companies for decades, detecting the movements of people and objects. ![]()
