Description
  • This paper deals with the application of High Altitude Platforms for the provision of third generation mobile services in sparsely-populated areas or in developing countries. It foruces on the behavior of large cells provided via a multiple HAP deployment and shows the possibilities of using small cells located inside these large cells to serve hot-spot areas. The impact of the different types of HAP antenna masks and their adjustment on cell capacity and the quality of coverage is presented. The main parameter of the antenna radiation pattern under investigation is the power roll-off at the cell edge. Optimal values of this parameter are presented for different scenarios. Simulations of system level parameters were based on an iteration lopps approach.

  • Tato práce se zabývá aplikací tzv. platforem ve ve velkých výškách (High Altitude Platforms - HAPs) k poskytování 3G mobilních služeb v řídce zalidněných oblastech. Je zde kladem důraz na chovávání velkých buněk poskytovaných HAP stanicemi ve vícenásobném rozmístění a ukazuje možnosti využití malých buněk umístěných uvnitř těchto velkých buněk za účel obsloužení hot-spot oblastí. Je zde prezentován vliv různých typů anténních charakteristik a jejich přizpůsobení na kapacitu a kvalitu pokrytí. Jsou zde dále prezentovány optimální hodnoty poklesu zisku antény (roll-off) na okraji buňky vzhledem k maximální hodnotě pro rozdílné scénáře. Simulace systémové úrovně jsou založeny na principu iteračních smyček. (cs)
