Improving UMTS and HSDPA Coverage 5-Fold With Inward-Facing Cells in a Simulcast Architecture

UMTS and HSDPA are the preferred services in many markets, but challenges with interference and isolation among the RF cells are reducing bandwidth and coverage in dense areas and inside buildings. This paper proposes a supplemental UMTS/HSDPA network architecture that cost-effectively improves service by increasing isolation to reduce interference while increasing data speed bandwidth and coverage. Therefore improving network efficiency and reducing mobile operator production costs.
