全球衛星互聯網市場(2023-2033)Global Satellite Internet Market 2023-2033 |
衛星網路是一種透過地球軌道上的通訊衛星提供的網路服務。 它是傳統地面網路連線(例如電纜/DSL 和光纖連接)的可行替代方案。 衛星互聯網的主要優勢之一是它能夠在地面互聯網基礎設施有限或不存在的地區提供覆蓋。 衛星網路可以到達鋪設電纜或建立地面基礎設施困難或昂貴的地方,例如偏遠地區、農村地區、島嶼和海上船舶。
通常位於低地球軌道 (LEO) 的小型衛星星座提供衛星網路服務。 這些衛星星座由數百到數千顆衛星組成,它們協同工作以提供全球覆蓋範圍。
範例包括 SpaceX 的 Starlink、OneWeb 和Amazon的 Project Kuiper。 衛星互聯網的工作原理是在地面用戶終端(例如衛星天線或相控陣天線)與太空衛星之間發送訊號。 用戶終端向衛星發送請求,衛星將訊息轉發給網關(地面站)。 使用者可以透過連接到網際網路骨幹網路的網關來存取網際網路。
由於用戶終端、衛星和地面站之間的距離而導致的訊號傳輸延遲是衛星互聯網的問題之一。 雖然傳統的地面網路服務通常具有較低的延遲,但衛星網路的延遲可能較高,因為訊號往返太空需要更長的時間。
然而,與傳統的地球靜止衛星互聯網相比,使用LEO衛星星座可顯著減少延遲。
儘管衛星網路速度隨著時間的推移而提高,但它們通常仍然比地面寬頻連線慢。 衛星上網速度和頻寬由衛星系統設計、網路容量和用戶需求等因素決定。 然而,大型衛星星座的部署提高了可用速度和頻寬,從而導致比以前的衛星系統更快的網路連線。

Satellite internet is a type of internet service that is delivered via communication satellites in orbit around the Earth. It is a viable alternative to traditional terrestrial internet connections such as cable, DSL, or fiber optic connections. One of the major benefits of satellite internet is its ability to provide coverage in areas where terrestrial internet infrastructure is limited or non-existent. Satellite internet can reach remote and rural areas, islands, ships at sea, and other locations where laying cables or establishing ground-based infrastructure would be difficult or expensive.
Small satellite constellations in low Earth orbit (LEO) typically provide satellite internet services. These constellations are made up of hundreds, if not thousands, of satellites that work together to provide global coverage.
SpaceX's Starlink, OneWeb, and Amazon's Project Kuiper are examples of such constellations. Satellite internet works by sending signals between a ground-based user terminal, such as a satellite dish or phased array antenna, and the satellites in space. The user terminal sends requests to satellites, which relay the information to gateways, which are ground-based stations. Users can access the internet through gateways that connect to the internet backbone.
The latency or delay in signal transmission caused by the distance between the user terminal, satellite, and ground-based stations is one challenge with satellite internet. While traditional terrestrial internet services typically have low latency, satellite internet can have higher latency due to the time it takes signals to and from space.
However, when compared to traditional geostationary satellite internet, the use of LEO satellite constellations has significantly reduced latency.
Satellite internet speeds have improved over time, but they are still generally slower than terrestrial broadband connections. Satellite internet speed and bandwidth are determined by factors such as the design of the satellite system, network capacity, and user demand. However, with the deployment of large-scale satellite constellations, available speed and bandwidth have increased, resulting in faster internet connections than with previous satellite systems.
