Intelsat Epic NG - High throughput, Ku-Band spot beams |
The high throughput of the EpicNG satellites comes from using small (<20) spot beams that, some studies suggest, will have a higher throughput per MHz than the proposed Ka Band satellites.
While traditional Ku-Band satellites use wide beams covering thousands of square miles, the EpicNG satellites will use a combination of wide beams and spot beams in C, Ku and Ka bands. The comparison of Ka and Ku Band throughput shows that beam performance is largely independant of frequency band and mostly dependant on the size of the spot beam.
The Ku-Band spotbeam downlink will have speeds up to 160 Mbps and uplink speeds of 4 Mbps and widebeam downlink speeds of 40 Mbps.
The first two satellites using the Intelsat EpicNG platform will be Intelsat-29e and Intelsat-33e, scheduled for service in 2015 and 2016, and covering most of the populated continents and the North Atlantic flight routes.
This will be in an open architecture allowing access from any teleport within the footprint to maritime, mobility and fixed terminals of 1.2m - 2.4m.
This is expected to result in a lower cost ber bit and the service should be a major player in the maritime market.
