Assessment methods for antenna spatial separation of UMTS and LMDS systems in view of intersystem EMC

The paper presents an analysis of the possible collocation of 3G systems and LMDS. The analysis particularly addresses intersystem EMC for a given set of parameters defining the LMDS system (operating frequency: 10.5 GHz, QPSK modulation) and the collocation of UMTS and LMDS base station antennas on a common mast).
