An Estimation of the Achievable User Throughput with National Roaming.
(English)Manuscript (preprint) (Other academic)
National roaming, that is allowing users to access networks of multiple domestic operator's, was discussed already during development of first and second generation mobile systems.For mobile voice services, however, the operators afforded to build networks with (almost) full coverage alone. The benefits with national roaming, in terms of increased coverage, trunking efficiency and lowered risk exposure, did consequently not exceedthe drawbacks associated with increased operator cooperation.Motivated by the considerable investments for providing coverage for mobile data services, and enabled by the commonradio resource management proposed for systems Beyond 3G,this paper1 evaluates the benefits with national roaming for besteffort data services. The results show that national roaming more than doubles the data rates for users at the cell border. Thisg ain is motivated by reduced path loss and lowered interference levels. Around half of the potential gain is captured already with nearly co-sited base stations, which suggests that the benefits for operators to coordinate their base station site plans are limited.
