Cost/revenue optimisation in multi-service mobile broadband systems

Multi-service traffic has a strong impact in Mobile Broadband Systems (MBS) revenues, allowing one to obtain merit functions for optimisation purposes. A ‘net cost’ model is presented for the design trade-offs between re-use pattern, K, the coverage distance, R, and the spectral efficiency, Sef(R). It allows for the determination of the revenue per basic channel, R384, that achieves a given value for the annual profit per kilometre. Comparing the urban with the roads scenarios for R = 100 m and K = 2, whereas (Sef)TOT = 32.2 and 15.2 %, R384 has to be 0.005 and 0.045 €/min, respectively, i.e., the prices in the roads scenario (with higher terminal mobility) have to be around one order of magnitude higher than in the urban one.
