Dear Mr.Eric

Hello

We need to established a SCPC link b/w Riyadh, Saudia and Korea could you please suggest a satellite KU band and C band both.

Asiasat 5 satellite at 100.5 east has Ku band spot beams aimed at the Middle East and East Asia.

Contact details: https://www.asiasat.com/asiasat/contentView.php?section=63&lang=0

NewSkies have NSS-6 at 95 east.

You need to ask if they have two transponders, cross strapped between these two beams so you can rent your required go/return bandwidths in the respective transponders.

If you plan to install and operate your own premise antennas at each end then ask what size dishes etc that your require.

Satellite service companies exist to help you, if you need design, consultancy, procurement, installation and maintenance. Some such companies may respond here with alternative suggestions.

I have put together details of some companies operating in the Asia region here: https://www.satsig.net/ivsat-asia.htm but I have not updated that page for some time. You can look and ask them all. It won't do any harm. Almost certainly there are alternative satellites, such as Intelsat that will have suitable Ku band spot beam coverages.

Wide area C band beams also exist which will include both of your sites, but to operate in such a broad beam will require you to have fairly large earth station antennas. Advantages of a broad C band will be lower outages during rain and that you can see your own signals. If you contemplate C band check for local WI-MAX interference in the vicinity of both end sites.

Note that regulatory transmit licence approvals will be needed.

Best regards, Eric

Do you have contacts details of both satellite providers ?

See the coverage maps above and with each are links to the contact details of AsiaSat and NewSkies (SES). If you contact them they can help with the leasing of transponder bandwidth in each direction, assuming spare capacity is available. What bit rates do you require in each direction ? You need to design the system yourself and provide and install earth stations with modems at each end. For example, you may need dish sizes 1.8m - 2.4m, Comtech CDM570 or iDirect 5350 SCPC modems plus LNBs and 5 watt BUCs.

If you want some satellite communications service company to do it all for you, then see page https://www.satsig.net/ivsat-asia.htm for some ideas. I've put email addresses for all the companies.

You ask for SCPC service. SCPC is suitable for long term continuous, non-interrupted, transmission requirements, such as music, video and speech. Because it uses the satellite transponder banedwidth all of the time and thus provides a dedicated 24/7 service it is expensive. (approx $2500 - $7000 per MHz per month)

The alternative is a shared VSAT network design which allows many, ten to thousands of customers to share the same satellite transponder capacity, but each customer must accept that they can only transmit or receive for a small proportion of the total time. Congestion, interruptions and delayed packets may occur. Prices seem very much lower (e.g. $40 per month for 15 kbit/s average), but if you add all the payments from the all the customers together the total price is the same as dedicated SCPC.

Best regards, Eric.
