12. Difference compared to P2P Radio Network
David Shiu
Difference compared to P2P Radio Network
Low-order modulation scheme
Both bandwidth and power are matter
A perfect balanced network: 50-to-50
(Bandwidth vs. Power of the satellite transponders)
Some networks are power-limited
RF Power means money vs

Applications

23. Applications Flyaway SNG Terminal Maritime Connectivity
Flyaway SNG Terminal are widely applied in meetings and events live without the restriction limitation, which via the satellite to transport the real-time image, voice, and data among multi points .
Flyaway SNG Terminal
Vessels at sea rely on broadband connectivity and VSAT technology to stay in touch with operations on land, increase work productivity and improve the quality of life for the 1.2 million seafers who are the backbone of the maritime industry.
Maritime Connectivity
At present, the banking industry, oil, earthquakes, weather, news, military and other departments have established their own VSAT communications network, which promote VSAT station to develop to the trend of transportable ,broadband, and low cost.
Transportable VSAT Stations
By 2016, 48,000 sites will use small cells with satellite as the primary source of backhaul for remote and rural connectivity. The market is on pace to achieve a 102% CAGR, driven by demand for 3G and 4G service in remote and rural areas.
Mobile Backhaul
SatCOM in the Communication-On-Moving filed has the advantage of global coverage and network security to provide reliable communication, developing speedy in the business continuity, military defense, emergency response, and more fileds.
