According to foreign media reports, the global broadband network speed test website speedest Net operator Okla released the latest data show that although SpaceX's satellite link Satellite Internet service has just completed the test phase, its average download speed in 15 countries now exceeds 100Mbps The < p > < / P > < p > satellite chain relies on a satellite network called "constellation", which currently includes more than 2000 satellites. In contrast, the competing viasat service has only eight satellites. This makes SpaceX by far the world's largest satellite internet service operator, and the company plans to launch tens of thousands of more satellites with its reusable rocket The distributed characteristics of < p > satellite chain satellites enable them to provide services at a faster speed and lower delay than traditional Satellite Internet. Ookla compared the star chain with HughesNet and viasat, which carved up the satellite Internet market before the star chain. The average download speed of HughesNet and viasat is about 20MBps and the upload speed is 2-3mbps < p > by the fourth quarter of 2021, the average download speed of star chain in the United States was 104.97mbps and the upload speed was 12mbps. But even in the United States, the performance of the star chain is not consistent in each region, and there are great differences between counties. Among them, the star chain network performed best in Miami Dade County, Florida, with a maximum download speed of 191.08mbps, while the download speed in Columbia County, Oregon was only 64.95mbps The < p > Star chain has achieved similar success in many other countries, surpassing its competitors in Australia, Austria, Belgium, Brazil, Germany, Ireland, Italy, Mexico, New Zealand, Poland and Portugal. It is worth noting that the star link network speed is faster than that in the United States in some countries, such as Australia, with a download speed of 141.55mbps < p > however, the network speed of the star chain is still lower than the average speed of all fixed broadband in the United States, and the download speed of the latter is 131.3mbps. In terms of upload speed, the performance of star chain is worse, and the upload speed of fixed broadband is higher than 19.49mbps

Satellite Internet, which is too long for real-time applications such as video chat. Viasat currently has a delay of 627 milliseconds and HughesNet has a higher delay of 725 milliseconds. The delay of star chain is only 40 milliseconds, which is not far from the average delay of fixed broadband of 14 milliseconds < p > the network speed of the star chain is constantly improving. As SpaceX continues to deploy satellites in batches, the service will only become faster and more extensive. However, SpaceX is trying to cope with high demand and insufficient supply. The delivery time of ordering its user terminals has been postponed to 2023 or later < p > in addition, the service cost of star chain network is not cheap. SpaceX recently launched Starlink premium as an alternative to more demanding users who want higher connection speeds from 150Mbps to 500mbps, which costs up to $500 a month. The standard service charge is $100 per month, but the speed is much lower, ranging from 50Mbps to 250mbps < p > another problem is that satellites in the satellite chain are easily damaged, but this may not directly affect users. In February this year, dozens of satellite chains were destroyed in a geomagnetic storm, which was a major economic loss for the company. (small) < / P > < p >
