Phys.org reports that "A team of researchers is working on technology that would allow mobile devices to send and receive more data using the same limited amount of bandwidth. The work is supported by a $1.08 million grant from the National Science Foundation (NSF - now in "outage") .. One way to get more use of the available bandwidth is through a technique called multi-input, multi-output (MIMO) communication, which uses the same radio frequency to transmit more than one stream of data simultaneously .. However, implementing the MIMO concept in small, mobile devices has been problematic .. Now a team of electrical engineers is working to develop a new radio receiver system that will allow small mobile devices to use MIMO technology. The system will include multiple antennas, a reconfigurable circuit, and new signal processing algorithms".
"We hope to have a proof of concept using two receivers by fall of 2015 and three to four receivers by fall of 2017," says Brian Floyd [pictured], an electrical engineering researcher at NC State who specializes in circuit design and is principal investigator (PI) of the NSF grant. "These approaches could allow the benefits of MIMO to be applied to systems in small devices, enhancing the download speeds for many common applications".
