The field testing, which began in Los Angeles on Sunday, showed 741 Mbps download speeds using 80 MHz of aggregated spectrum. While LTE-U doesn't present many challenges as far as integration with other network services, the potential for interference and crosstalk with other users of the unlicensed spectrum is very real, making it extremely hard and important to implement protections that will keep that from happening. T-Mobile says that its LTE-U service, using the 5GHz band, is live in six locations in the United States, with more to follow. The network announced that it's making LTE-U available to the people which means LTE capacity is getting a boost.
T-Mobile's LTE-U is now available in the above mentioned cities, as well as Bellevue, WA, and Simi Valley, CA - however, only in "select locations" within the cities.
Increase in LTE speed is one of the focus areas for US-based telecom operators such as Verizon, AT&T, Sprint and T-Mobile.
T-Mobile said the field tests will help it test new products in a controlled environment outside the lab.
T-Mobile is launching support for unlicensed spectrum to bolster download speeds in smartphones and tablets on its network. And to T-Mobile's credit, it does march to the beat of its own drum. LTE-U availability will be expanded later on this year, though T-Mobile doesn't say to what extent.
T-Mobile likes to talk up its network enhancements, and today the magenta carrier made two more announcements.
The carrier will add small cells with LAA functionality to add density to its network starting later this year. While our competitors scramble to deal with the way unlimited data plans are slowing down their networks, we're already moving on to what's next.
In its filing, the Un-carrier asked the Commission for permission to extend its testing of LTE-U equipment through December 28.
