D-MIMO

Technical Explanation

In traditional cellular topologies, signals from adjacent base stations interfere with each other, degrading signal quality. Distributed MIMO (D-MIMO) connects multiple physically separated remote radio heads via fiber fronthaul to a shared baseband processor. Signals from multiple sites arrive coherently at the user device, transforming what would have been harmful inter-cell interference into constructive signal diversity and spatial multiplexing throughput.

Key Functions

• Coherent joint transmission from geographically distributed radio points
• Eliminating edge-cell signal degradation in dense urban macro and micro environments
• Virtual cell formation following moving users across city blocks without handovers
• Exploiting diverse angular arrival angles to combat line-of-sight shadowing
• Substantial improvement in spectral efficiency and uniform service availability
