Mass transit is one of the best options for change. Many of us would ride mass transit if it was readily available. But I think many more would be inclined to ride if the metro offered internet access. Extra Wi-Fi time instead of the stasis of looking at

I want comfort and the ability to work, which is helped greatly by having Wi-Fi. Trains are generally several leagues above planes when it comes to comfort. If they throw in high-speed Wi-Fi, I’m sold (as long as the price isn’t too high). I’m

The aim of the research is to improve the wireless sensors deployed in remote areas where the wi-fi is reliant on batteries or energy-harvesting devices for power. “Ultra-low power consumption is one

The antenna has demonstrated a 30-times-stronger signal transmission over on-chip antennas at 135 GHz. It’s also tiny, approximately the size of a sesame seed, making it is the
