UMTS Repeater Systems for Spectral exchange between the UMTS frequency bands, as well as access method

摘要

Where systems are constituted by: (a) one or more Cellular UMTS base stations that provide Communications Services to the nearby Cellular UMTS Terminals within its coverage area and connected via cable to (b); (b) one or more repeaters near communicated with (c) in another of the B You're UMTSVia radio; (c) one or more repeaters Remote communicated with (b) in a UMTS bands, and (d) in a UMTS Bands; and, d) Cellular UMTS Communications with Remote Terminals through (a) (b) and (c).Uses a mechanism of rejection of interfering Terminals based on the Phase Distortion of the signal transmitted between (b) and (c) to prevent the intrusion of (d) the communication between repeaters; a mechanism of Equalization with receptors (b) and (c) for Communication between ell You,Compensatory Distortion effects; a limitation mechanism of radiated and received signal gain of (b) and (c); and a Cutting mechanism of radio transmission of signal in (b) and (c) when the corresponding input signal is below a threshold adjustable by the operator
