Although existing Galaxy S4 models already had the previously fastest fourth-generation (4G) data rate, using a standard that’s been available for several years called Long-Term Evolution (LTE), this new device represents the first deployment of the next-generation standard, called LTE Advanced (LTE-A). Samsung is partnering with
Qualcomm has been itching to get LTE-A out there, and with the Samsung win, the U.S. chip designer’s high-bandwidth dream finally becomes a reality in splendorous color.
The key feature that makes the Galaxy S4 the snappiest of smartphones is so-called “carrier aggregation,” a special feature of LTE-A devices and networks. Simply put, carrier aggregation lets the operator gang different slices of spectrum together to create higher bandwidth.
When LTE was first rolled out, operators anxious to get going used whatever spectrum they had available, which in many cases was limited to band snippets 5-to-10MHz wide. With these thin slices, networks could achieve data rates that were respectable, but not appreciably better than those of dual-carrier HSPA+, the best available third-generation (3G) technology, which can handle data rates of up to 42 megabits per second.
Now, with the Galaxy S4 LTE-A roll-out, smartphone users can expect mobile broadband downlink data rates of up to 150 megabits per second, twice as fast as the most highly optimized LTE network, and all this goodness comes in a power-sipping, highly mobile package.
No word yet on when U.S. operators
Just think about what data rates like that mean. Theoretically, with the new Galaxy S4 LTE-A, you could blow through your entire 5 gigabyte monthly data allotment ($50 on Verizon) in less than five minutes.
Apple? Your move.
