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.
For example from the chart below, the 1-A and 1-B channel for Butts County, GA.
Market: BEA040 - Atlanta, GA-AL-NC
Call Sign: WPQV559
Market: PEA011 - Atlanta, GA
Call Sign: WRBI208
Call Sign: WRBI209
The mapping of original call sign / channel to the new call sign / channel is available in our Web Spectrum Viewer, Transactions Menu.
