Millimeter wave: Myths vs. realities

Millimeter wave frequencies will be a central part of delivering the ultra high capacity data throughput associated with 5G, but, given its unique propagation characteristics, putting high-band spectrum to work is a challenge.

During a keynote session at 5G World, Samsung Networks VP and Head of Technology Strategy Group Wonil Roh, highlighting a number of test scenarios, set to work separating fact from fiction when it comes to millimeter wave.

First up, Roh took on the cell density required to provide millimeter wave coverage in a congested, outdoor, urban area. Because millimeter waves don’t travel near as far as their sub-6 GHz counterparts, there’s something of a notion that providing coverage will require incredibly dense networks. Not so, Roh said.
