The Effect of System Architecture on Net Spectral Efficiency for Fixed Services

The Effect of System Architecture on Net Spectral Efficiency for Fixed Services
02 December 2011
This white paper analyses the spectral efficiencies of point-to-point (PTP) and point-to-multipoint (PMP) fixed service architectures for mobile broadband backhaul.

The properties of mobile broadband backhaul traffic are examined with reference to a network case study.

The analysis shows that a PMP topology increases spectral utilisation significantly, resulting in a modal increase in net spectral efficiency of 50%.

Considering the projected growth in mobile data consumption, we argue that the gains possible with a point-to-multipoint architecture are increasing with trends in RAN design towards high peak rates and small serving cells.
