AI Thread Summary
4G LTE can theoretically be used on Low Earth Orbit (LEO) satellites, but the design must differ significantly from terrestrial systems due to the vast coverage area and shared spectrum among users. A major challenge is the backhaul process, as LEO satellites are not geosynchronous, complicating data transmission to ground networks. Unlike terrestrial mobile traffic, which efficiently routes to a fixed network, satellite broadband requires careful management of traffic backhaul. There are existing standards for satellite communications, such as those developed by 3GPP for UMTS, but specific adaptations for 4G LTE in satellite contexts may be necessary. Overall, while feasible, implementing 4G LTE on LEO satellites presents unique technical hurdles.

A satellite mobile system needs to be designed differently to a terrestrial one, because the coverage of the satellite is so huge and the spectrum resource is shared between so many users. In addition, the backhaul from the satellite for a Leo is a significant problem because it is not geosynchronous. Terrestrial mobile traffic is back hauled to the switching centre and a large fixed network, which we would like to avoid with a satellite. For satellite telephony, the two users will often be within the same coverage area, but for broadband this is not the case and traffic has to be back hauled.
 
Are there any special standards designed for satellites? I know 3GPP has a special standard for satellite in UMTS.Senmeis

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
