Samsung Announces The Galaxy Note 4 LTE-A Tri-Band CA Model With Download Speeds Of Up To 300Mbps.

There's no such thing as a connection that's too fast. Samsung seems to be following that sentiment with the latest variant of the Galaxy Note 4, officially announced this weekend. The new Note 4 has something called LTE Advanced Tri-Band Carrier Aggregation, which is a fancy way of saying that its mobile download speed is faster than just about anything else on the market. Samsung claims the phone can download files at a speed of 300mbps, faster than all but the most advanced wired connections.

The Tri-Band Carrier Aggregation feature basically opens up multiple LTE bands and initiates a sustained download across three data connections at once, combining them for faster delivery. It's not unlike some of the "download boosters" available for desktop browsers, though this requires considerably more hardware engineering to achieve. Samsung estimates that a 700MB video (a standard-def movie) could be downloaded to the phone in about 19 seconds.

Of course, actually finding a carrier that can provide that kind of bandwidth is no easy task. In order to take full advantage of this Note 4's speed, you'd need to use it on a carrier with three different frequencies of LTE-Advanced spectrum. This is an example of manufacturers outpacing the carriers in terms of hardware innovation, so this Galaxy Note 4 variant is unlikely to be made available outside of South Korea any time soon. (Sprint has announced that it will enable carrier aggregation sometime next year with peak speeds of 150-180mbps, and some carriers allow dual-band aggregation for 50mbps+ speeds.) Samsung did not elaborate on an international launch, though we may see more widespread phones with Tri-Band Carrier Aggregation as new models are introduced next year.
