MIT researchers have found a way to transfer wireless data using a smartphone at a speed about three times faster and twice as far as existing technology.
The researchers developed a technique to coordinate multiple wireless transmitters by synchronizing their wave phases, according to a statement from MIT on Tuesday. Multiple independent transmitters will be able to send data over the same wireless channel to multiple independent receivers without interfering with each other.
Since wireless spectrum is scarce, and network congestion is only expected to grow, the technology could have important implications.
The researchers called the approach MegaMIMO 2.0 (Multiple Input, Multiple Output) .
For their experiments, the researchers set up four laptops in a conference room setting, allowing signals to roam over 802.11 a/g/n Wi-Fi. The speed and distance improvement is expected to also apply to cellular networks. A video describes the technology as well as a technical paper (registration required), which was presented this week to the Association for Computing Machinery’s Special Interest Group on Data Communications (SIGCOMM 16).
The researchers, from MIT’s Computer Science and Artificial Intelligence Lab, are: Ezzeldin Hamed, Hariharan Rahul, Mohammed Abdelghany and Dina Katabi.
