Module 1 – Satellite Link

Presented by: Tanawat Tatiyavoranat

Agenda

Satellite Communication Link Budget Calculation Satellite Technology in the Internet

Link Budget Calculation

The calculation to find C/N of link The efficiency of link Tx power to use Size of satellite dish Prevent satellite equipment operate at

saturated point (HPA, Satellite)

Satellite Technology in the Internet Single Carrier Per Channel (SCPC) Multiple Carrier Per Channel (MCPC)

– DVB-RCS– Gilat Technology– iDirect

Module 3 – Power Generation

Presented by: Erik Ehrlund

Module 3 - Power Consumption

Different devices consumes different amount of power.

The values below are from our test equipment– Server ~60-100W– Vsat equipment ~40-60W– Linksys wrt54gs ~6W (Wireless AP)

Module 3 - Power Generation

Renewable power – Solar power

• 1000 W/m^2 for optimal conditions• Don't work during the night

Module 3 - Power Generation

Diesel power– Diesel generator

• Reliable but needs a lot of maintenance• High upkeep costs• Overkill

– Usually a diesel generator is able to generate well above 2kW

Module 3 - Power Generation

Other solutions– Hand or bicycle driven generators– Wind power– “Wave” power– And so on
