Nokia and T-Mobile announced a 3GPP-compliant lab demonstration of bi-directional, over-the-air data transmission at 28 GHz. The companies claimed the demo, which was conducted in T-Mobile’s Bellevue, Washington lab, is “the nation’s first” meeting the 3GPP new radio (NR) specifications.

The test used Nokia's AirScale 28 GHz radio and baseband, with an AirFrame server and AirScale Cloud RAN running 5G NR 3GPP-compliant software. The other end of the link used simulated user equipment.  

”This successful 3GPP compliant over-the-air data transmission represents an important step for T-Mobile and the commercialization of 5G. By building on the tests Nokia has previously conducted with T-Mobile, T-Mobile is well on its way to 5G commercial deployment." — Marc Rouanne, president of mobile networks at Nokia
