In addition, T-Mobile field tested License Assisted Access (LAA). The testing began yesterday in Los Angeles and resulted in download speeds of 741Mbps using 80MHz of aggregated spectrum. With this technology, T-Mobile can combine unlicensed and licensed spectrum (with greater carrier aggregation than LTE-U) to offer more bandwidth and faster speeds. And the same features that T-Mobile uses to beef up its 4G LTE pipeline will also work with LTE-U. In these areas, LTE-U is now limited in the spectrum it can use, which is where LAA comes in. T-Mobile LTE-U is live in select locations in Bellevue, WA; Brooklyn, NY; Dearborn, MI; Las Vegas, NV; Richardson, TX; and Simi Valley, CA.
Expect to hear more from T-Mobile about its LTE-U and LAA strategies in the coming months - especially in relation to how far behind AT&T and Verizon are in achieving the same thing.
As previously reported by TeleGeography's CommsUpdate, in February this year the Federal Communications Commission (FCC) took steps to authorise LTE-U devices in the 5GHz band. "This means that the fastest LTE network - that's T-Mobile - will only get faster".More news: At last minute, Western Digital resubmits bid for Toshiba chip unit
In a parallel United States trial, AT&T Mobility has confirmed that it has teamed up with Ericsson to conduct its own live LTE-LAA field tests, reaching initial wireless speeds of more than 650Mbps in downtown San Francisco. LTE-U provides similar speed and capacity benefits for consumers as the trifecta of technologies T-Mobile launched last fall - Carrier Aggregation, 256 QAM (Quadrature Amplitude Modulation) and 4x4 MIMO (Multiple Input Multiple Output) - with less licensed spectrum. T-Mobile plans to roll out small cells that include LAA technology later this year. "The trials at the various locations listed below will allow T-Mobile to test prototype equipment in outdoor and indoor setting prior to equipment certification ..."
"LAA is the the latest example of how T-Mobile is innovating the way forward".
