As T-Mobile’s LTE network continues to roll out in large swaths, so does our wish to use it to its full potential. It’s also true that with the addition of mobile hotspots into just about every smartphone under the sun these days our need for independent mobile hotspot devices wanes a little, but that doesn’t end the need completely.

Thanks to a pair of shots captured from a Samsung training manual, we’re getting our first look at an upcoming T-Mobile branded LTE Mobile Hotspot. The specs are pretty standard for a hotspot and there’s no “wow” factor here and it won’t do your laundry or cook you dinner. It will however last up to 39 hours when connected to LTE or 30 hours when connected to 3G/2G. When you ask why there are still Mobile Hotspots on retail shelves, that battery life is one of the biggest reasons.

Given how much of a battery drain a mobile hotspot connection can be on your smartphone, this image and the battery life should be reason enough to shell out some cash once this hotspot arrives. T-Mobile now sells the Sonic 2.0 Mobile HotSpot LTE, their first such LTE hotspot. It currently sells for $29 down and $5 per month or $149.99 outright. I expect that the Samsung hotspot will be similarly priced when it arrives.
