NBC Sports used our network emulator to test the satellite communications link between Beijing and New York prior to the Olympics. How would the television transmission perform faced with common satellite issues: solar blanking? MPEG breakup? Rain fade? Macroblocking?
NBC Sports simulated all these conditions, and characterized areas requiring improvement, enabling them to mitigate, compensate and improve their television transmission before the start of the Olympics. Then, when they deployed to the live satellite, there were no surprises.
Radio, television, telephone, internet communication, GPS and other navigation, scientific and photographic instruments are examples of applications that use satellites.
The most common characteristic of satellites is latency; the greater the distance travelled, the greater the delay in packet transmission. Low earth orbit satellites range from 180 to 2000 km, but geostationary satellites can be 35,786 km from the earth, or roughly 22,000 miles!
Unfortunately, for something as common as accessing a web page (which requires TCP setup, TLS authentication, DNS fetch) multiple round trips are required, adding at least one or two seconds of delay (compared to ground communication). Thus the app design requires expertise in compression, caching, and other techniques to reduce the round trips.
Select one of the KMAX "Satellite Scenarios" -- low earth orbit satellite, geosynchronous satellite, streaming media over satellite, and so on.
The data flowing between your devices will be affected in exactly the same manner as if the data was carried by a satellite. KMAX will let you see how well your app or device performs in the lab, before deployment.
You can easily modify any of the parameters. Or use KMAX's waveforms to pace or time the onset, duration, intensity, and falloff of any of the likely impairments.
