Modern wireless standards promise to enable high throughput wireless links by using multiple antennas on the UEs and Basestations. However, the increase in the number of antennas do not lead to proportional increase in the achieved link througput. The primary reason for this is that the wireless channel do not have good enough multipath and is not well conditioned to support projected MIMO throughput. As shown in Fig. 1a, closely spaced antennas on the device have correlated wireless channels and do not allow for efficient spatial multiplexing of data streams.
Fig 1: Smartsurface can lead to multiplexing gain
In this project, we increase the multiplexing capability of the wireless channel by creating new multipath in the channel. We achieve this by designing smartsurfaces that can be deployed on walls as shown in Fig. 1c to create diverse paths from a UE to Basestation. The smartsurfaces create a strong reflection and makes the wireless channel well-conditioned to support multiple spatial streams.
