It’s a problem that’s rapidly getting worse as more and more devices require access to the cloud, not to mention the constant strain of searching for a good signal or boosting a weak one. The student researchers invented a new type of hardware that uses 10,000 times less power than traditional Wi-Fi networking equipment. It’s called Passive Wi-Fi, (you canread their paper here) and it works just like a home router, just more efficiently. To give some perspective, the state of the art in low power Wi-Fi transmissions today consume 100s of milliwatts of power, whereas the technology the student researchers developed consume only 10-50 microwatts—10,000 times lower power.
