Sprint's mobile data is typically not the first, or the second, or even the third to come to mind when looking for a zippy connection in the US, but the company is looking to change this impression with its new tri-band LTE network, more memorably known as Sprint Spark. Unfortunately, only a limited number of the carrier's phones are able to take advantage of this new capability, with some of them requiring an OTA before they're ready.
Sprint wants everyone to know about its tri-band LTE network that could potentially reach speeds of 50 - 60 Mbps, so it gave it a catchy name - Sprint Spark. Once the rollout is complete, this could be the largest LTE network in the US in terms of spectrum usage. But that's the future. Right now, the network is available in only a handful of cities (Chicago, Los Angeles, Miami, New York, and Tampa), and even fewer phones are currently set to tap into it (okay, just one).
While Sprint's tri-band LTE network is far from a secret, the company's going on an all-out marketing offensive promoting the technology, which it's now given a name: Sprint Spark. Capitalizing on the unique capabilities of its newly-purchased Clearwire spectrum, Sprint is set to roll out what will likely be the US's largest LTE network in terms of spectrum usage over the coming years. That's primarily because Sprint's Clearwire acquisition granted it a block of wireless spectrum from 2500-2600MHz, the single largest contiguous frequency lease in use by any mobile data provider in the United States.
