Satellite bandwidth cost

Internet via satellite phone Bandwidth varies from about 2400 bit/s for Iridium network satellites and ACeS based phones to 15 kbit/s upstream and 60 kbit/s downstream for Thuraya handsets .

The bandwidth of a typical transponder is 36 MHz . If we employ 12 such transponders with 4 MHz of guard band between each transponder, then accommodation of 12 transponders in 500 MHz bandwidth is achievable.

Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks.
