[1] This is a study to quantify U.S. wind power at 80 m (the hub height of large wind turbines) and to investigate whether winds from a network of farms can provide a steady and reliable source of electric power. Data from 1327 surface stations and 87 soundings in the United States for the year 2000 were used. Several methods were tested to extrapolate 10-m wind measurements to 80 m. The most a...

Levels of power flux-density (pfd) and fractional degradation in performance are presented as thresholds for coordination of frequency assignments for non-geostationary orbit (non-GSO) space station transmitters in the mobile-satellite service MSS and receiving stations in the fixed service (FS) in frequency bands shared between these services in the 1-3 GHz frequency range. In the annexes, the...

Wireless mobile backhaul networks have been proposed as a substitute in cases in which wired alternatives are not available due to economical or geographical reasons. In this work, we study the location problem of base stations in a given region where mobile terminals are distributed according to a certain probability density function and the base stations communicate through microwave backhaul...

Heterogeneous network (HetNet) consisting of many small base stations (SBSs) within a present macro base station (MBS) is considered. The impact of SBS power on/off is discussed on network power consumption, throughput, and handover, and also the decentralized dynamic channel assignment. Keywords— heterogeneous network; power on/off; handover; throughput; channel assignment

Cellular networks represent one of the major energy consumers of communication networks and their contribution to the global carbon footprint and energy consumption continuously and rapidly increases. Improving energy efficiency of the cellular access networks become an important requirement and has recently gained considerable attention of the research community and operators. In this paper, i...

We present the bit error performance and capacity of the reverse link of a DS-CDMA cellular system, taking into account the effect of power-controlled interfering users from other cells. A convolutionally encoded, BPSK modulated, waveform is considered. The channel is assumed t o undergo flat Rayleigh fading, which is typical of narrowband C D M A systems. All the mobile users are power-control...
