Sprint 4G Rollout Updates

Monday, October 21, 2013 - 3:55 PM MDT

Clarification: Many readers seem to be confusing the previously authorized and officially announced tri band Samsung Galaxy S4 Mini with this tri band Galaxy S4 reboot, which is full size. The two have quite different model numbers -- the Mini is SPH-L520, while as stated below, the tri band Galaxy S4 is SPH-L720T. Sprint has not yet formally acknowledged the latter, but it has passed FCC OET authorization. And S4GRU expects it to be another tri band handset available before the end of the year.

To alleviate the confusion, we are planning an overview article on Sprint Spark tri band handsets, probably to coincide with the November 8 street date next week for the first group of released handsets.

Six months ago, S4GRU published an article breaking down the FCC authorization documents for the Sprint variant Samsung Galaxy S4.

Many were disappointed that the Galaxy S4, like all other Sprint LTE devices for the past year, was limited to single band 25 LTE 1900. It was not a Sprint tri band LTE handset -- even though band 26 LTE 800 and band 41 TD-LTE 2600 seemed to be right on the horizon because of the impending shutdown of the Nextel iDEN network and the likely approval of the SoftBank-Sprint-Clearwire transaction. Indeed, with the arrival of several Sprint tri band mobile hotspots, TD-LTE 2600 started to become available in metros around the country late this past summer.

Today, we bring you another teaser article. The FCC OET database this afternoon uploaded the authorizations for this Samsung model number: SPH-L720T. Now, if you are familiar with the Galaxy S4, you know that its Sprint variant model number is SPH-L720. So, it does not take a genius to put 2 + 2 together. Or in this case, to put S4 + 2 together.

Yes, Samsung has just revealed a Sprint tri band Galaxy S4. It carries very similar specs to those of the original Galaxy S4, but it adds two additional Sprint bands: band 26 LTE 800 and band 41 TD-LTE 2600.

So, between the previous release of the single band Galaxy S4 and the almost inevitable upcoming release of the tri band Galaxy "S5," look for a tri band updated variant for the Sprint Galaxy S4 in the coming months, probably before the end of the year.

Rest assured, this handset will be of popular interest among the faithful -- and possibly despised among those who already used a subsidized upgrade on a single band Galaxy S4 -- so we will run a full FCC OET RF breakdown in the coming days. To head off the obvious questions in the meantime, no SVDO, no SVLTE, as expected.

Before we go, though, view the antenna diagram below to see the Sprint tri band LTE goodness.

As always, stay tuned...
