Low Cost PLDROs for LMDS/MVDS Applications for 40 GHz Band
Low Cost PLDROs for LMDS/MVDS Applications for 40 GHz Band A.Lázaro, D.Girbau, P.de Paco, L.Pradell Universitat Politècnica de Catalunya (UPC), Barcelona (Spain), pradell@tsc.upc.es In HFC systems the infrastructure cost is dominated by the final distribution, the so-called "last mile". Market studies demonstrate that MVDS (Multipoint Video Distribution System) becomes even more attractive than HF
