Infostation overlays in cellular systems
Jordi Borras, Roy D. Yates · 2003
We address the use of existing cellular infrastructure as the location for Infostations, an array of isolated wireless ports delivering wireless data services. The coverage area of an Infostation, though, will be smaller than the cell area. We determine the worst-case SIR as a function of the coverage-radius-to-cell-radius ratio and the frequency-reuse cluster size. For specific modulation schemes, we identify desirable operating points and calculate the Infostations' utilization.
