New Wi-Fi Technology that Can Make Internet 10,000 Times Faster

While scientists from all over the world continue to make enormous advances in the field of technology, we are getting closer and closer to that moment when the eternal struggle of Wi-Fi battery drain will come to an end. For over 4 years, electrical engineer Oded Kariti has been researching various techniques that could improve its efficiency. But thanks to the constant strain of searching for a good signal or boosting a weak one, and of course the ever-increasing number of devices that require access to the cloud, it has only become a problem that’s rapidly getting worse.
In order to provide you with a better perspective of this complex matter, Oded Kariti starts by explaining that today's Wi-Fi transmissions consume 100s of mW of power, and the new technology is expected to consume only 10 to 50 uW, which is around 10,000 times lower power. Typically Wi-Fi requires two or more devices that use an analog radio frequency to receive and transmit signal, but only one produces a radio frequency. That same frequency is related to your Wi-Fi-enabled device through separate sensors that only have baseband chip and an antenna since it requires almost no power. Once the sensors pick up the signal they mirror it in and send readable Wi-Fi to any device that has a Wi-Fi chipset in it.

The new "passive" Wi-Fi runs on low power and isn’t transmitting any signals. Oded Kariti explains that this new Wi-Fi is created just by reflection, instead of using a full radio signal.  If this new type of technology takes off, Oded Kariti expects a number of devices connected to the Internet to significantly increase, as it nullifies the previous energy constraints of making a device Wi-Fi compatible. This networking equipment could save on energy costs, prevent greenhouse gas emissions, and still keep the network equally secured. Because of its power constraints, Wi-Fi hasn’t always been the best choice for connecting our Internet-ready smart devices, but in the future, all of these may change thanks to this new type of technology.
