Descripción
The roll-out of UMTS/HSPA networks in 900MHz band offers the possibility to bring 3G and mobile broadband services to new areas with less base station sites and to improve the indoor coverage in the existing UMTS coverage areas. This paper presents the benefits in term of savings on site numbers and on network-related costs provided by the roll-out of a mixed-frequency UMTS network (networks with carriers operating at 900 and 2100MHz) instead of a single UMTS2100 network. These results are presented for dense urban, urban, suburban and rural areas and for three demand scenarios. Despite the higher reductions on site number are achieved for the lower demand scenarios, savings higher than 30% are found even in the higher demand scenarios. Regarding the costs savings, the higher savings are obtained in the greenfield roll-out scenario. Lower cost savings are achieved in the brownfield scenario but the introduction of a UMTS900 layer results in a more cost efficient solution than the maintenance of the single frequency UMTS2100 network.
