ion of compliance with a wide-area license at an international or a license area boundary, that is, compliance with a maximum electric field strength at a certain height above ground could also be used as the compliance con- dition for a local license at the boundary of the facility acquiring the license. There is also no reason to believe unwanted emission metrics should vary depending on the size of the license area. Timely availability of spectrum under suitable licensing conditions could create a major growth area for the economy while enabling non-eMBB aspects of 5G toward implemen- tation of Time-Sensitive Networking (TSN) and end-to-end integration of services, which 7 The license area size for terrestrial mobile systems vary from as large as nationwide to as small as counties. 8 Listen-Before-Talk (LBT) has been the foundation that enabled many consumer applications including Wi-Fi and Bluetooth, and will continue to benefit future applications including many in the 5G era. It is, however, anticipated that confined spaces of many industrial facilities, that is indoors, would reduce the inefficiencies of the "polite protocols" by moving toward more deterministic behavior for a specific set of use cases. Therefore, some level of time-synchronized scheduling implemented in the license-exempt protocols, for example IEEE 802.11ax, could increase reliability to levels required by some applications. 2.6 Network Deployment Models is needed if the full potential of 5G is to be reached. A few countries in Europe and Asia have already started, or plan to start soon, the process of allocation of spectrum for use by vertical industries in a locally licensed manner. It is also important for regulators to assign locally licensed spectrum within the ranges already defined in NR specifications in 3GPP to take advantage of economies of scale. 2.6 Network Deployment Models Traditionally, each mobile operator deployed and operated its own network. However, in order to decrease CAPEX and OPEX of RAN, which are substantial, op
