Samsung unveiled the Galaxy S5, its first high-end Android-powered flagship smartphone of 2014, at the Mobile World Congress in Barcelona last month, However, the South Korean company omitted to inform us that an exclusive LTE-Advanced AT&T variant would also be landing in the States, along with the 4G model. A recent FCC filing shows that the upcoming S5 variant will support AT&T’s LTE and HSPA data services — bands 2, 4, 15 and 17 — thus confirming the existence of LTE Advanced capabilities on the handset.

The Federal Communications Commission documentation reveals that the LTE Advanced smartphone will too to be powered by a Qualcomm MSM8974AC Snapdragon 801 chipset powered by four 2.5GHz Krait 400 central processing units, an Adreno 330 GPU, 2GB of RAM, 16GB of internal storage (expandable up to 128GB), a 16-megapixel rear-facing camera, a 2-megapixel front-facing shooter and a 2,800mAh removable Li-Ion battery.

Sadly, the filing doesn’t provide any clues with regards to a launch date for this model, but we already know that the factory unlocked Galaxy S5 will launch in the United States on Friday, April 11, 2014. So, hopefully, we won’t have to wait long until AT&T publishes a pre-order page for its yet-to-be announced LTE-A variant.
