Satellite Internet has always been seen as an alternative to terrestrial networks that do not reach many areas because of the lack of commercial interest or the difficulty of wiring. However, we have never had a project that has provided a real alternative in speed and latency. Not at least until SpaceX has come on the scene. Its broadband Internet for satellite Internet will arrive in 2019 with 25 ms of latency and gigabit speed.
SpaceX has unveiled plans to create a constellation of 4425 satellites capable of delivering broadband that will be launched by the Falcon 9 rocket in early 2019. The deployment of this satellite network will be completed in 5 years and will be finished and running at full capacity in 2024.
SpaceX: Satellite Internet with 25 ms and gigabit speed
The company founded by Elon Musk has updated its plans to deploy a top-performing satellite network. As we know, this technology currently suffers from high latencies, relatively low speed and downloads limits similar to mobile data rates.
However, all this may be in the past with the plans announced by SpaceX. The launch date for the first units is 2019. By the end of this year, the company will start the testing process for satellite units and will be launching a prototype before the end of this year as well. If everything goes according to plan, the first unit will be launched in 2 years.
The 4425 satellites will operate in 83 different orbits with altitudes between 1100 kilometers and 1325 kilometers. In addition, they will need ground support in the form of base stations that will be in charge of control and other tasks. However it does not end there, SpaceX also wants to launch another 7500 satellites that will be even closer to ground. These will be responsible for improving latency and capacity in highly populated areas.
At present, about 1500 satellites orbit the Earth. If the SpaceX project is completed successfully, that would mean multiplying the number of these devices in space by three. Some companies believe that this will trigger the risk of collisions between units.
SpaceX’s broadband satellite network will function as a mesh or mesh network. It will be able to “focus” capacity in those areas where it is most needed. In addition, the signal will reach directly to receivers placed in the homes of customers, eliminating intermediate devices. These will be the size of a laptop and will offer gigabit speeds and latency of 25 ms.
