Cost/Revenue Optimisation of Multi-Service Cellular Planning for City Centre E-UMTS
Fernando José da Silva Velez, Nuno Anastacio, Francisco Merca, Orlando Cabral · 2007
An overview of all-IP enhanced Universal Mobile Telecommunication System, E-UMTS, service needs in the business city centre, BCC, scenario is first presented. Then, E-UMTS traffic generation and activity models are described and characterised. System level simulations are carried out and the enhanced performance is demonstrated based in a single quality parameter, which simultaneously accounts for call blocking and handover failure probabilities. End-to-end delays do not present a limitation. By considering a grade of service of 1% for the quality parameter, and different hypothesis for costs and prices, an optimum coverage distance is obtained around ~200-425 m, which maximises the supported throughput per km2. However, results for the profit in percentage indicates that coverage distances in the range 395-425 m should be used in BCC.
