Sweet-spot spectrum for enterprise 5G is growing, but slowly

The mid-band is valuable because it’s in a “Goldilocks” zone of the wireless spectrum—its frequencies are high enough to support higher throughput, while also being low enough to propagate effectively across relatively large areas. The major wireless network providers are desperate to acquire as much of it as they can, to deploy 5G as widely as possible. While there’s plenty of spectrum available in the millimeter-wave range above 30GHz, those frequencies don’t travel as far, meaning that orders of magnitude more base stations would be required to cover a given area.
