Upper Microwave - New Channels and New Call Signs (39GHz) September 04, 2018 00:00

In our September 2018 Millimeter Wave - Spectrum Ownership Analysis Tool, we have incorporated the FCC's re-licensing of the 39GHz into the new Upper Microwave Flexible Use Service.  In making this change the FCC issued new call signs and leases for all of the 50 x 50 MHz channels.  The call signs have been reissued on a Partial Economic Area (PEA) market frame work.  Previously these licenses were issued on a Economic Area (EA) basis. The original channels were lettered A through N.  Now they are numbered 1-14 with the A designation for the uplink channel and the B designation for the downlink channel.

The FCC reissued this spectrum with a different call sign and channel number for each of the original channel blocks.  Issuing a separate call signs will make it easier to combine the 2-50MHz blocks into 1 -100MHz block as indicated in the Fourth Further Notice of Proposed Rulemaking below.
