Obtain the leftmost, rightmost, and rightmost value of the layer element in the visible area of the browser.

Are you still complaining about too few WIFI hotspots and unstable signals? In the future, if you have a light bulb, you will have wireless network signals, and the transmission speed will be as high as 1 Gbps, much higher than that of WIFI. This technology was invented by Herald Haas, a British university technician, and his team-the use of light to transmit data, often known as visible light communication VLC ). However, there is no obstacle to achi

The Mexican team has achieved 10 Gbit/s visible light wireless data transmission
Speaking of "optical transmission", we are most likely to think of the optical fiber technology used for long-distance data transmission. But if the transmission distance is short, do we still need to "constraint" the optical signal in the optical cable? Unlike Wi-Fi and Bluetooth, there are already multiple research teams in the world studying short-range wireless tra
