5G and 6G: Capacity and Coverage Requirements Will Drive Unique Network Products and New Spectrum Usage

This presentation examines the future profile of mobile data demand and will illustrate the network topology and spectrum options that best fit. Repeaters, IAB, Cognitive Radio, Sub-THz, and other radio solutions are considered. In particular, the future requirements for coverage will drive a need for repeaters and IAB solutions, while future requirements for capacity will push the market in the opposite direction, toward higher order massive MIMO, sub-THz (~140 GHz) spectrum, and other high-density solutions. Difficulties with high-frequency penetration into buildings will limit the impact of sub-THz and mm-wave, so indoor deployment, Cognitive Radio, and new bands below 12 GHz will play a role in future network
