The power consumption of wireless access networks will become an important issue in the coming years. In this paper, the power consumption of base stations for mobile WiMAX, HSPA, and LTE is modelled. This power consumption is related to the coverage of the base station. The considered technologies are compared according to their energy efficiency for different bit rates at a bandwidth of 5 MHz. For...
Nowadays, wireless access networks are a large contributor to the CO2 emissions of ICT. Today, ICT is responsible for 4 % of the annual energy consumption and this number is expected to grow drastically in the coming years. The power consumption of these wireless access networks will thus become an important issue in the coming years. In this paper, the power consumption of wireless base stations...
The radio coverage of 2.5 GHz mobile WiMAX for five different terrain categories, three antenna modes and 90% service reliability are estimated using a combination of COST-231 Hata and SUI Erceg models. Based on the planned cells, the call holding time in a given cell and channel throughput of the mobile WiMAX for multimedia services are simulated to observe the relationship among vehicle speed, antenna...
