T-Mobile Hits 741 Mbps with LTE-LAA, Deploys LTE-U
T-Mobile today said it, too, has successfully tested LTE-LAA in real-world trials. The company claims its LTE-LAA tests reached 741 Mbps in and around Los Angeles. Like the recent tests conducted by AT&T, T-Mobile's use of LTE-LAA combines airwaves that it owns along with unlicensed spectrum to push speeds upward. T-Mobile says it was able to aggregate 80 MHz between licensed and unlicensed spectrum in its trials to attain the 741 Mbps download rate. More importantly for the short term, T-Mobile has deployed LTE-U in some markets. LTE-U relies on public 5 GHz spectrum (same as WiFi) along with advanced network technologies including carrier aggregation, 256 QAM, and 4x4 MIMO to boost LTE performance. T-Mobile is offering LTE-U in Bellevue, Wash.; Brooklyn, N.Y.; Dearborn, Mich.; Las Vegas, Nev.; Richardson, Texas; and Simi Valley, Calif. More markets will score LTE-U service later this year. Right now, the Samsung Galaxy S8 is the only device able to take advantage of LTE-U.
The S8 is Samsung's flagship phone for 2017, and it combines absolutely every idea Samsung has ever come up with for a high-end phone, plus a couple of new ones. From the extra-tall curved display to the iris scanner, to a new voice assistant, Samsung is throwing down the gauntlet.
Samsung's new virtual reality headset adds a controller, which dramatically helps improve usability. Together with a Galaxy smartphone, the Gear VR and controller will allow you to dive headfirst into exciting virtual worlds.
Smartphone cases must outnumber smartphones 10 or 20 to 1. Finding the right combination of style, usability, protection, and price takes more than just a few moments thought.
Living the unlocked life is living the best life, at least when it comes to your smartphone. Many handset makers offer unlocked versions of their top devices, including, as of this week, Samsung.
Samsung announced the Galaxy S8 and S8+ this week, its flagship smartphones for 2017. These powerful handsets arrive with new screen shapes, slim silhouettes, and bulked up specs.
