How do you know that the real world speeds we'll see on Verizon LTE are 5-10mbps? I clicked the link but that had nothing to do with Verizon's deployment.
If it's really only 5-10 that's pretty fast but disappointing at the same time.
That's because a single "device" has the network all to itself, the rest is guestimates and conjecture...
Are you assuming that they tested the throughput with only 1 device?
Not to mention testing LTE on a cell site hooked into the same backhaul that is running 3G in the first place. In other words there are lots of devices being used already.
