Google’s project Loon under the Microscope: Internet via balloon

Google’s project Loon made ​​in the last days of discussion . By means of this project, the Internet can bring to via balloons in disaster areas or similar. 30 balloons floating in the stratosphere and is currently being tested there. They float in the stratosphere at an altitude 18 to 27 kilometers, approximately every 100 days must be refilled.

The signals are passed to special antennas on the radio frequency and then forwarded to the commercial routers. Here is evident: sweeping the signal is not available to everyone, it still requires a hardware component on the ground – the special antenna. The traffic in the network is transmitted to balloon ground stations and are fed into the cable network.

The balloons as such can be any time locate and remotely control that controlled lands should be practiced only in specific areas, for emergency use, the balloon and its technology is to be slowed down by parachute.

Certainly should be apparent that the project Loon is nothing for the average consumer only once – in the event of a disaster but it could benefit from an existing Internet draw attention to themselves.

I once researched and looked to see what there is still so off to find from Google information on the Internet about the project Loon something. In New Zealand, there were Wigram Airforce Museum a launch event, which answered many questions and yet also produced many photos. Four balloons float above the field, 50 testers are still working to use the project Loon.

A Reddit member was there and has also shot photos and questioned the employees present. A balloon has three ARM processors under the hood, which each serve out part of their own work. The software for the Loon is based on C + +. The balloons are permanently connected to the base station and monitored. Using solar power comes to the technology.

The balloon is working on the basis of 2.4 GHz and 5 GHz. The 2.4 GHz band is used for communication between the nodes and Loon on earth. The 5 GHz band between the balloons with their three antennas. The whole thing is reminiscent of standard Wi-Fi, but this protocol for its own interests was rebuilt.

The speed between Loon and client is symmetrical, so the speed is up and down the same and should correspond to the 3G standards. User data will be encrypted twice.


, Seen here is the silver rectangular battery that is said to have ten times the capacity of a laptop battery. Due to the fluctuating temperatures, this battery has a built-in heater, because the loon is exposed to temperature ranges between -40 ° to +25 °. The other components to be heated. The balloons float, as already mentioned, at a height 18 to 27 kilometers, or about twice as high as the civilian air traffic. During takeoff and landing, however, it is in contact with the normal civil aviation. Balloons make what was probably no hazard – 70,000 weather balloons ascend it every year.
