enarios such as those involving ambulances, air ambulances, fire trucks, and police vehicles. Local-Area Broadband Emergency responders Public Safety connectivity between including law enforcement, the the CN and the fire service, paramedics, and tactical cells. medical professionals can set up a tactical cell where needed for their operations. This cell can be connected to a 5G system via SATCOM, to exchange voice, data, and video-based services between public safety users within a tactical cell or with the remote coordination center. The NB-IoT/eMTC support in an NTN is critical for operating IoT services in remote and otherwise inaccessible areas (https: /www.gsma.com/iot/narrow-band-internet-of-things - nb-iot/). Some of the industries and operational areas in need of proper NB-IoT coverage include the following: Transportation (maritime, trucking, railways, and aviation), distribution, and logistics Solar, oil, and gas exploration and production Energy and utilities Farming and agri-tech Environment monitoring, including monitoring of pollution in oceans Mining and natural resources SATCOM networks complement TNs to connect the dots between IoT services today present in dense urban areas only. The 3GPP work item for NTNs is contained in R-17 on an NTN for NB-IoT and eMTC. 3GPP's goal is to reuse as much knowledge as possible from the TN for the NB-IoT/eMTC design. 5G core connectivity may be considered as part of R-18 or later specifications. 5G and Satellite Communications In this section, we have looked at the various use cases that the intersection of SATCOM and 5G enables for enterprises, government and the military, as well as consumers. Summary In this chapter, we have learned about 5G and satellite communication. We looked at use cases that are enabled by network slicing. After an introduction to satellite communication, we learned why it is needed in the context of 5G networks. Finally, we learned about its architecture and use cases. In the upcoming chapter, we will introduce automation, orchestrati
