The fact that Sprint and Clearwire have teamed up to deliver WiMAX to New York, LA, and San Francisco isn't news. In fact, we've already seen the networks light up in operational readiness modes on the way to full consumer availability. But now we've got dates, the first specifics that we can recall for these cities. Now, according to both Clearwire and Sprint, New York's WiMAX service will go live on November 1st, LA's on December 1st, and San Francisco sometime around the end of December. We'll see if those early 5Mbps to 7Mbps download / 1.2Mbps upload speeds we've experienced can be maintained once the service meets the crush of the big city horde. Of course, this is nothing but good news for wireless consumers who'll also see Verizon light up its competing LTE network in these cities (38 in total) at about the same time.
