Samsung crams even faster LTE into the Galaxy Note 4
The Galaxy Note 4 is already one of Samsung's best smartphones, but a new modelfocused on maximizing 4G could make it more of a catch. The LTE-A Tri-Band CA Galaxy Note 4 (what a mouthful) can handle three different frequency bands simultaneously and aggregate them into a single, theoretically faster connection. The improved handset, which Samsung says is the first "commercially available" smartphone with such a setup, supports both Category 6 (up to 300 Mbps) and Category 9 (up to 450 Mbps) LTE networks -- but the kicker here is its ability to pick out and jump between the best available bandwidths.
