When Sprint announced that Baltimore would be the location of the first roll-out for Xohm, a new long-range wireless broadband technology known more lately as “Clear,” I could hardly believe it. Baltimore is not particularly known as a hub of technology. Want crabs, we got ’em. Under Armor, we’ve got that too. But when it comes to releasing new technology, Baltimore is typically toward the bottom of the list. While most of the surrounding Baltimore County has Verizon’s FiOS, residents in the city are still waiting.
