Not to be outdone with Verizon Wireless’ announcement of its LTE Advanced deployment a week ago, T-Mobile has revealed that it has successfully doubled the connection speed of its data network by way of 4x4 MIMO (multiple input, multiple output). According to the third biggest wireless carrier in the United States, 4x4 MIMO allows for significantly faster transmissions of data by increasing the number of data paths two fold between a mobile user’s handset and a cellular site.
As stated by Neville Ray, the chief technical officer of T-Mobile via a blog post, the 4x4 MIMO technology is now made available in 319 cities across the US. Ray added that owners of Samsung’s current flagship devices, the Galaxy S7 and the Galaxy S7 Edge, will be able to start taking full advantage of the tech before the end of September through a software update. T-Mobile also said that other mobile devices will soon have support for 4x4 MIMO.
T-Mobile notes that its network already provides coverage for almost 312 million mobile users, while also mentioning that it reaches 99.7 percent of the number of users that industry leader Verizon Wireless has reached. Ray also took the opportunity to reveal that T-Mobile now can claim that it is the first mobile operator based in the US to deploy 256 QAM (quadrature amplitude modulation) for downloads and 64 QAM for uploads. By pairing 256 QAM with its 4x4 MIMO, the wireless carrier can offer download speeds of up to 400 mbps. In the blog post, Ray also stated that 256 QAM and 64 QAM are now activated in half of T-Mobile’s network, and it should go live in every cellular site across its US framework before the start of November this year.
Just before the end of August, Verizon Wireless had announced the deployment of two and three channel carrier aggregation, promising to deliver 50 percent faster peak data connection speeds to its subscribers in 461 cities across the US. Through the use of 700 MegaHertz, AWS and PCS spectrum, the Big Red is joining two or three of the channels to bring data over the most efficient path to mobile handsets.
Ray, however, claimed that as early as a couple of years ago, T-Mobile had already been offering its subscribers access to two channel aggregation, adding that the wireless carrier has also already rolled out three channel aggregation. Ray also wrote that the reason industry leaders Verizon Wireless and AT&T still do not offer unlimited high speed data to every subscriber is that their respective networks just could not effectively carry all that load.
