September 29, 2008: That Monday was the fateful day of Sprint-Nextel’s long-awaited WiMAX rollout. Xohm launched commercially in Baltimore to great anticipation in four forms: a $35/month modem plan, a $45/month mobile service for use with a PC ExpressCard, a $65/month “pick 2″ plan, and a $10/day tryout, but it’s really the second option that brings something new to the table. Internet anywhere in a city? No wires? And not even that, but faster than your usual cabled setup too! So needless to say, many have already taken Xohm out for a (literal) test drive, so much so that the ExpressCards are selling out in stores.

The bottom line? PC Magazine and Information Week both seem to agree–the new service is undoubtedly fast. PC Magazine’s Sascha Segan: “With a strong signal, I saw download speeds averaging 3.6Mbps, with my fastest test at a blazing 7.1Mbps. That’s faster than my home cable connection!” But “strong signal” are the operative words; the new network still has a lot of gaps to fill. J. Nicholas Hoover of Information Week confesses to having run across a few “dead zones” in areas that were stated as covered, and signal fluctuations were common, as Segan elaborates: “At a shopping mall…I had a significantly stronger signal on the south side of the mall than on the north side.“  But, he continues, “[T]hat’s to be expected from a new wireless network in its first week…Networks start out patchy and then fill in.”

So Sprint’s WiMAX network is far from perfect. But for now, Baltimore residents should be glad to have 35 mph streaming video. Next up is Chicago and D.C.; the former is already getting hyped up with an exhibit in the Museum of Science of Industry featuring a three-story WiMAX-enabled Smart Home. And if you aren’t in Baltimore but are in the seven announced near-future sites (Chicago, D.C., Dallas-Fort Worth, Boston, Providence, Philadelphia), you may still be able to take advantage of fixed WiMAX speeds!
