Impact of Latency on Services

High latency in satellite networks significantly hinders the efficiency and responsiveness of services, posing challenges for real-time communication applications. Satellite networks operate by transmitting signals to and from satellites orbiting the Earth, which introduces a delay in data transmission known as latency. This delay can range up to 700 milliseconds, far exceeding the response times of Local Area Networks (LANs) which typically operate between 1-3 milliseconds. Wide Area Networks (WANs) also experience latency, with delays ranging from 10-300 milliseconds, predominantly due to satellite communication.
When services rely on real-time communication, such as video conferencing or online gaming, the impact of latency becomes more pronounced. High-latency satellite networks can cause delays that disrupt the flow of communication, leading to lag in audio and video transmission. Chatty applications, which frequently exchange small amounts of data, are particularly vulnerable to slowdowns or timeouts when operating over satellite networks with high latency.
Compared to wired or wireless networks, satellite networks inherently introduce higher latency due to the distance signals must travel to reach the satellite in orbit. As a result, applications designed for low-latency networks may require adjustments to function optimally over satellite connections, ensuring users receive a seamless and responsive experience despite the inherent delays.

Understanding Latency in Satellite Networks
Latency in satellite networks arises predominantly from the extensive distance signals must traverse to establish communication with satellites positioned in geostationary orbit. When a signal is transmitted from Earth to a satellite in geostationary orbit, it has to cover a round trip of approximately 44,872 miles. The following points help in understanding the intricacies of latency in satellite networks:
- Speed of Light: The speed of light, which is approximately 186,282 miles per second, determines the upper limit of how fast a signal can travel. Despite traveling at the speed of light, the vast distance the signal needs to cover introduces latency in satellite communication.
- Signal Path Length: The longer path length that signals have to travel in satellite networks compared to terrestrial networks contributes significantly to higher latency. This extended path increases the time taken for data to reach its destination.
- Earth's Influence: The signal has to travel through the Earth's atmosphere, which can cause delays and interference, further adding to latency in satellite communication.
- Lower Latency Solutions: To counter the high latency inherent in satellite networks, advancements like lower orbit satellite constellations and innovative signal processing techniques are being developed to reduce latency and enhance overall network performance.
