The Argos project pushes MU-MIMO to its limits, scaling up the number of antennas in wireless systems to a point previously thought impossible. This enables us to achieve enormous capacity and power gains, and discover the true real-world limits of MU-MIMO.
Building a many-antenna base station is non-trivial. Scaling up baseband processing, clock distribution, transmission synchronization, and channel estimation raises serious system challenges. Moreover, the cost, size, and power consumption of the base station limit the practicality of the many-antenna approach. Our work has already revealed many new research challenges on every level of the architecture.
While the Argos project is still in its infancy, we have already demonstrated compelling early results. Our many-antenna architecture is able to improve spectral capacity and energy efficiency manyfold simultaneously.
