Correia, “Cost/Revenue Optimisation in Multi-service Mobile Broadband Systems,” in Proc. of PIMRC’ 2002-13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, Lisbon, Portugal, Sep. 2002.http://hdl.handle.net/10400.6/14485Multi-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, S/sub ef/(R). It allows for the determination of the revenue per basic channel, R/sub 384/, that achieves a given value for the annual profit per kilometre. Comparing the urban with the roads scenarios for R=100 in and K=2, whereas (S/sub ef/)/sub TOT/=32.2 and 15.2%, R/sub 384/ 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.engCost/revenue optimisationMulti-serviceMobile broadband systemsTelecommunication trafficUrban areasMultimedia systemsconference object10.1109/PIMRC.2002.1046684
