The ultra-slow Wi-Fi at your local coffee shop could soon be getting a big boost.
At the moment, Wi-Fi networks can only serve one device at a time, cycling quickly among different users. That creates slower speeds for everyone when more devices connect to the network.
“On a network like this, streaming or video chatting can be like sitting in the driver’s seat at rush hour: you’ll get to your destination, but it’s going to take some time,” Qualcomm said.
The company’s new approach, which follows seven years of research, allows networks to transmit data to multiple groups of users simultaneously using algorithms that adapt on the fly to changes in usage. The technology is known as “MU-MIMO,” which stands for “multi-user, multiple input, multiple output.”
Qualcomm plans to sell MU-MIMO-enabled chips to manufacturers of wireless routers and access points, as well as to companies that make smartphones, tablets and other consumer electronics.
