The FCC Office of Engineering and Technology (OET) has granted three experimental licenses to Qualcomm Technologies to test C-band 4G/LTE equipment. License WH2XIN allows mobile operation in San Diego, using the 3550-3650 MHz band “to evaluate a downlink LTE system.” WH2XIO allows similar mobile operations in Mayport, Fla. WH2XIM covers testing 4G/LTE mobile in Raleigh, N.C. in the 3.5-3.6 GHz band. C-band satellite operators and users have expressed concern over interference to 3.7-4.2 GHz satellite downlinks. This week's RF Short has a link to a report from Peter B. de Selding on reallocation of C-band spectrum to terrestrial broadband.
