<\/p>\nUniversity of Washington (UW) in Seattle is one of the top institutes of higher learning in the\u00a0United States. The researchers at the UW come up with some interesting and amazing discoveries. Just recently, with the help of\u00a0research that was funded by the National Science Foundation, the University of Washington and Qualcomm,\u00a0the\u00a0computer scientists and electrical engineers at the UW\u00a0demonstrated that you can achieve WiFi transmissions using almost no power at all. I know it sounds crazy but check this out. They are able to\u00a0generate “passive” WiFi transmission that uses 10,000 times less power than conventional methods.<\/p>\n
The following video demonstrates how this technology works. Normally, in a WiFi transmission, there is an analog and digital operation involved in the radio transmissions. It’s not the digital component that eats up all the energy because it has been tweaked enough over the past few decades, it’s the analog portion that’s the culprit. The researchers at UW essentially separated the two components, which resulted in WiFi transmissions that use extremely low power. Click the image below to watch the video to and see how it works.<\/p>\n

You can only imagine what Passive WiFi can do for Internet of Things (IoT). It’s likely to have a significant impact on the IoT phenomenon and opens up the door to other advancements in wireless technologies.<\/p>\n
\u201cWe wanted to see if we could achieve Wi-Fi transmissions using almost no power at all,\u201d said co-author Shyam Gollakota, a UW assistant professor of computer science and engineering. \u201cThat\u2019s basically what Passive Wi-Fi delivers. We can get Wi-Fi for 10,000 times less power than the best thing that\u2019s out there.\u201d<\/p><\/blockquote>\n
