In summary, the conversation discusses the use of 4G LTE on LEO satellites to provide a base station in space. The speaker notes the challenges and differences in designing a satellite mobile system compared to a terrestrial one, such as the need for a different backhaul solution. The question is also raised about special standards for satellites, to which the speaker mentions a 3GPP standard for satellite in UMTS.

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
 

1. What is LTE for satellites?

LTE (Long Term Evolution) for satellites is a type of wireless communication technology that allows for high-speed data transmission between a satellite and a ground station. It is based on the same LTE technology used for mobile devices on Earth, but has been adapted for use in space.

2. How does LTE for satellites work?

LTE for satellites works by using a network of ground stations and satellites to transmit data between devices. The satellite acts as a relay between the device and the ground station, allowing for data to be transmitted over long distances at high speeds. The technology also uses advanced coding and modulation techniques to improve signal efficiency and reduce interference.

3. What are the benefits of using LTE for satellites?

There are several benefits to using LTE for satellites. Firstly, it allows for high-speed data transmission, which is essential for applications such as video streaming and real-time communication. Additionally, LTE for satellites is more efficient and reliable than traditional satellite communication methods, resulting in improved performance and reduced costs.

4. What are the challenges of implementing LTE for satellites?

One of the main challenges of implementing LTE for satellites is the need for advanced technology and infrastructure. This includes the development of specialized antennas and ground stations, as well as the integration of LTE technology into satellite systems. Another challenge is the potential for interference from other wireless systems, which must be carefully managed to maintain signal quality.

5. How is LTE for satellites being used currently?

LTE for satellites is currently being used in a variety of applications, including satellite internet services, remote sensing, and satellite broadcasting. It is also being explored for use in future space exploration missions, as it has the potential to greatly improve data transmission capabilities for spacecraft. As technology continues to advance, the use of LTE for satellites is expected to grow and become even more widespread.
