Achieving low-cost UMTS networks via pricing

摘要

One of the main concerns of mobile operators towards deployment of Universal Mobile Telecommunications System (UMTS) networks is the investment cost. The costly radio access network, based on the network equipment required in a service area, prevents incumbents and new entrants from upgrading or building a new UMTS network. In this article, a novel, low-cost approach to the UMTS radio access network design is proposed. The approach employs the use of pricing incentives. This approach is based on the assumption that a pricing mechanism is in place to control excessive traffic load during peak periods. By incorporating this assumption into the network design, the network designer is able to relax certain design parameters, which may contribute to significant savings in equipment cost. Investigation is focused on the UMTS coverage and capacity planning, using the Net Present Value (NPV) financial analysis. For certain price-sensitivity levels, the analysis indicates that this approach provides a suitable strategy for mobile operators to comfortably move forward with UMTS upgrade and gain competitive edge in the wireless market.
