Spectrum EfficiencySingle DCCH versus one DCCH per Radio Head





Virtual Single Cell Advantages• Efficient use of RF-Spectrum

– Single multi-casted Digital Control Channel– Pooled frequencies for entire system

• Voice quality– Channel follows mobile– Soft handoff

• Minimal cell planning– No cell relations within a VSC– Simplified Autonomous Private System
