Initial Study of the Local Multipoint Distribution System Radio Channel

摘要: A broadband millimeter wave study was completed to characterize the radio channel for Local Multipoint Distribution Systems in Boulder, Colorado. The determined characteristics proposed 20-MHz channels centered at 30.3 GHz using two transmitter heights a suburban environment. Distributions of delay spread, correlation bandwidth, frequency selective fading and scatter plots signal loss are presented. median 40-m height 15 dB. Maximum spreads this were below 10 ns with value less than 1 ns. Data also collected flat plate reflector use 28.8 GHz. Cross cell interference diffraction measurements made.
