5G Survives a Critical Test: The Backcountry

Researchers from New York University have offered a surprising demonstration of millimeter-wave wireless communications. 

While this largely unused and untested frequency band—usually assumed to be a key component of 5G—is characterized by its poor performance across long distances and among even low-density intervening objects (like bushes), engineering professor Ted Rappaport and colleagues found in experiments spread across the wooded, rural hills of southern Virginia that it performs much better than expected.
