VZW only holds 5 LSMH C-block licenses (which came from the ALLTEL acquisition, VZW itself never participated in the LSMH C-block auctions):
- CMA176 - Springfield, IL
- CMA196 - Champaign-Urbana-Rantoul, IL
- CMA250 - Bloomington-Normal, IL
- CMA399 - Illinois 6 - Montgomery
- CMA400 - Illinois 7 - Vermilion
By relinquishing every one of those LSMH C-block licenses, VZW is clearly indicating that they had no plans to ever utilize that band, so this is kind of a house-keeping effort as much as anything else.
Keep in mind that there are no handsets (or I should probably say chipsets) that support all SMH bands and blocks. VZW is focusing on USMH C-block, which they're currently deploying exclusively, with possible fallback on LSMH A- and B-block. Throwing LSMH C-block into the mix would have resulted in far too much complexity on the chipset/filter side, so they figured it's easier long-term to just get rid of those holding and refocus on something else.
FWIW, AT&T only holds LSMH B- and C-block licenses (and is acquiring LSMH D- and E-block from QUALCOMM). They have nothing in LSMH A-block or any of the USMH blocks.
Like I said, SMH chipsets do not work across all the various sub-bands and blocks, they're specialized and tuned to a couple blocks, and due to technological limitations that'll probably be that way for the foreseeable future. So unlike with PCS or AWS where one chip works across the entire band, top to bottom, SMH providers concentrate their holdings into a couple of blocks and order the corresponding chipsets for their handsets. It made perfect sense for VZW to rid itself of those 5 LSMH C-block licenses since they would not have been used in the foreseeable future anyways.
