Are you looking for capacity connected South America to South America ?
or
South America to North America plus North America to South America ?

How much bandwidth were you looking for each way?

Best regards, Eric.

Hi, sorry for not being more specific. Looking for South America only Ku band.
2 to 5ghz of available bandwidth in the transponder.
at least 3 year contract. For satellite ISP

Here below is an example Ku band beam, from a geostationary satellite, covering part of South America

...

If the capacity rented has connectivity South America to South America you will be able to see your own signals and communicate only between sites within the beam, so the ISP needs a teleport and customer remote sites all within the same beam. You might typically have a 4 Mbit/s download outlink carrier and four 256 kbit/s TDMA return link carriers, all shared amongst 500-1000 sites, each with about 4 PCs.

If the capacity rented has connectivity South America to USA or Europe and USA or Europe to South America then you will not be able to see your own signals. The ISP customer sites will be in South America and the hub teleport in USA or Europe. If the ISP wants multiple customer VSATs then a carrier plan like that above is suggested.  If the ISP simply wants an internet backbone connection then a 4 Mbit/s carrier Europe to South America plus 1 Mbit/s carrier South America to Europe is suggested.

Pricing for the above will be about $6000 to $7000 per MHz per month. Contact  latinamericasales@ses-newskies.com for availability (if any), exact prices and T&C.

Regarding capacity required, 2 - 5 GHz is quite unrealistic on existing satellites so I have illustrated an idea with 2 - 5 MHz above, which might be available.

If you really want 2-5 GHz then (high risk) ideas are to either get a conventional Ku band satellite built specially for yourself or to get involved with the O3B project (Ka band).  The O3B project plans 8 satellites (later 16) moderate altitude (8063km high) satellites going round above the equator. Customer sites are proposed to have two antennas, both with motorised tracking, and switch from one satellite to the next every 45 minutes (later every 22.5 minutes). Each satellite has a claimed capacity in excess of 10 Gbit/s and uses 12 spot beams. The system only serves latitudes +/-45 deg, but that includes all except the southern tip of South America.  Read more:  https://www.idirect.net/galleries/application_briefs/WHITE_PAPER_iDirect_Interop...
