High-speed wireless connectivity

Researchers at Purdue University are developing a new technology that converts laser pulses into radio signals so that home electronics can connect wirelessly to each other at much higher speeds. Current Wi-Fi networks.

The silicon resonance imaging system of the researchers receives laser pulses containing information and turns them into radio frequency pulses. These pulses help solve the problem that Wi-Fi signals encounter: noise when hitting the wall or ceiling and then pop out.

"The key to this technology is that our equipment generates ultra-wideband radio frequencies for high-speed data transfers ," said Andrew Weiner, a professor of electrical and computer engineering.

In addition, the device system has a data transfer rate of up to 5,000-6,000 Mbps (which can transmit all content in a Blue disc for 5 seconds), while Wi-Fi is only at 50-100 Mbps.

Researchers are marketing a one-way data resonance device. In the future, if the data transmission unit is integrated into the device, there will be two-way communication, allowing internet connection, or help some devices such as hard drives work without wires, said Associate Professor Minghao. Qi said.
