Millimeter-wave 5G was once heralded as the future of ultra-fast wireless connectivity, promising lightning speeds and near-instantaneous data transfer. But today, many are asking: Whatever ...

It also helps that millimeter-wave 5G signals are much more energy-dense than previous generations of licensed wireless technology, making them more suitable for energy harvesting.

The 5G mm-Wave Technology Market is experiencing significant growth, driven by the increasing demand for high-speed internet and enhanced mobile broadband services.

Millimeter-wave 5G will never scale beyond dense urban areas, T-Mobile says T-Mobile CTO says 5G's high-frequency spectrum won't cover rural America.
