Re: Do Satelites have routers in them?
said by raytaylor:Satellites contain lot more than just routers. All semicustom radhard modules, The system can be completely reconfigured to compensate for failures.
The article above says viasat has 140gbit of capacity through their new satelite - but when i read about how slow their service is, i keep thinking, alot of that bandwidth must be wasted due to latancy issues.
Slow speed us due to a heavy load. 10k users will easily use the bandwidth.
Latency and throughput are different concepts.
lutful... of ideasPremium
said by public:I just wanted to clarify that geosynch orbit broadband satellites do not have any router/bridge/switch for data. Essentially they create a simple RF repeater from customer to gateway. said by raytaylor:

I used to write about the Google funded "Other 3 Billion" O3B low latency and high throughput medium orbit satellite network ... it is finally ready to launch in 2013.
Their blog has cool photos of the satellites and gateways as they are being built. »o3bnetworks.com/additional-pages/blog
Even in such a sophisticated system, all those radiation hardened electronics are mainly for RF and control/maintenance. Still no router on board.
There are some low orbit satellites with router and storage functions but they are low bit rate and aimed at tracking and emergency messaging.
