T-Mobile Subscribers Upgrading to Samsung Galaxy S8 and Samsung Galaxy S8 Plus To Get Access to Fastest LTE Speed By Laurence Hao | Mar 30, 2017 02:05 PM EDT Following the launch of Samsung Galaxy S8 and Samsung Galaxy S8 Plus, T-Mobile announced that its subscribers will get to enjoy double LTE data speeds. The catch is they have to upgrade to Samsung's new flagship devices so as to get access to three advanced LTE technologies offered by T-Mobile. The Phone Arena reports that the T-Mobile subscribers who choose to upgrade to Samsung Galaxy S8 and Samsung Galaxy S8 Plus can take advantage of these three advanced LTE technologies already existing within the T-Mobile network: the 4x4 MIMO, Carrier Aggregation, and 256QAM. They will also be the first consumers to have access to the unlicensed spectrum on the 5GHz band called LTE-U. The 4x4 MIMO is reportedly configured to improve data speed by adding more connections between the cell tower and the Samsung Galaxy S8 and Samsung Galaxy S8 Plus. The Carrier Aggregation is adapted to increase the bandwidth so as to increase the bit-rate, while the 256QAM can increase the number of bits delivered per each transmission, thereby increasing the data speed. T-Mobile claims that the combination of these three advanced LTE technologies would allow T-Mobile subscribers switching to Samsung Galaxy S8 and Samsung Galaxy S8 Plus to download a 2-hour movie in just 15 seconds. In reality, however, these T-Mobile subscribers will not be able to fully maximize the gigabit speeds claimed by T-Mobile, according to Fortune. Interferences on cellular signals, such as trees and buildings and data traffic within the cell sites, will slow down the data speed. That said, even with these interferences, these three advanced LTE technologies would still double the LTE data speed already being enjoyed by current subscribers, at the very least. Meanwhile, these three advanced LTE technologies are available in 300 T-Mobile markets.
