| This article describes the modeling of a SATCOM link, specifically the use case of using a satellite overlay to extend service continuity to IoT devices in a poorly covered rural area. Non-terrestrial wireless networks (e.g., satellite constellations or high altitude platforms) have unique advantages—wide area service coverage and long-term reliability — which make them important components in the heterogeneous 5G global system of networks. Non-terrestrial networks (NTN) will likely play a critical role providing service to locations not covered by terrestrial 5G networks, such as rural and remote areas, moving platforms and disaster-stricken zones. One use case for NTNs is providing service continuity for machine-to-machine (M2M) or IoT devices as they move out of 5G terrestrial network coverage.1 This is particularly important for M2M/IoT devices which provide critical communications (e.g., applications in eHealth or vital asset tracking). | This article describes the modeling of a SATCOM link, specifically the use case of using a satellite overlay to extend service continuity to IoT devices in a poorly covered rural area.

| A simple antenna for LTE band operation is added to the PC board of a smartphone in XFdtd and the matching circuit is tuned for operation in multiple frequency bands. The components in the matching network are chosen to maximize system efficiency. | A simple antenna for LTE band operation is added to the PC board of a smartphone in XFdtd and the matching circuit is tuned for operation in multiple frequency bands.
