There has been some back and forth on Twitter this morning with Mike Dano, FierceWireless editor and Allnet Insights, the creator of the maps for the article.
Allnet Insights says that the maps only include the three largest channels of LTE spectrum that are, or will be part of a carrier aggregation strategy. Mike Dano feels like this was disclosed and I told him that I completely disagreed. The article doesn't even use the phrase carrier aggregation.
