China's first high-throughput communications satellite launch, how "high" it really is

It is said that: China's first high-throughput communication satellite practice thirteen in xichang satellite launch center successfully launched. Practice 13 satellite using higher frequency Ka band communications, with large capacity, small terminal, easy to equip and so on. It marks the entry of China's satellite communications into the high-throughput era.

The Practice 13 satellite adopts a completely different frequency from that of traditional communication satellites, which not only expands brand-new frequency space resources, but also makes the communication capacity of the satellite increase dramatically to 20Gbps, which is dozens of times that of the traditional communication satellites, and even exceeds the total capacity of all communication satellites developed in China before.

With such a capacity, the Practice 13 satellite can access 300,000 users at the same time and allow each user to enjoy a 100-megabit broadband wireless Internet experience. Therefore, Practice 13 satellite not only enables some remote areas to easily access broadband network, we will also be able to enjoy more stable and high-speed network communication services on high-speed railways and airplanes in the future.

In addition, the Practice 13 satellite will also be the first to verify the laser communication technology in high orbit. According to the plan, the practice 13 satellite after in-orbit verification, to determine these new communication technology is stable and reliable, not only will these technologies will be applied to subsequent satellites, but also, practice 13 satellite itself will be put into formal business operations, from a test satellite into a real communications satellite.
