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.

See Reducing Encumbrances in the 39 GHz Band

For example from the chart below, the 1-A and 1-B channel for Butts County, GA.

Old Records:

Market:  BEA040 - Atlanta, GA-AL-NC

Call Sign:  WPQV559

Channel A

New Records:

Market:  PEA011 - Atlanta, GA

Channel: 1-A

Call Sign: WRBI208

Channel: 1-B

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.


Millimeter Wave - Upper Microwave Flexible Use (Auction Channels) August 30, 2018 13:31

In our Millimeter Wave - Spectrum Ownership Analysis Tool, we have incorporated the FCC's re-licensing of the LMDS A band (27.500-28.350GHz) into the new Upper Microwave Flexible Use Service.  In making this change the FCC issued new call signs and leases for all of the previous LMDS A band BTA area licenses with L1 and L2 band Upper Microwave Flexible Use Service channels.  In the new framework (and our database) a new call sign was release for each channel (L1, L2) by county.  The remaining A band licenses remained LMDS licenses.

County Analysis:
As you can see in the image below, we still provide the county-level spectrum depth by frequency band for the entire LMDS band (purple).
But we also break out the L1, L2, A, and B channel's spectrum depth separately.  This is a useful view to determine if the L1/L2 channels will be available from the FCC in the November auction.
