Hybrid dual-band satellite communication system
First Claim
1. A dual-band satellite communication system comprising:
- a hub station including a hub transmitter operating on a first band frequency, a hub receiver operating on a second band frequency, and a hub server;
wherein said first band operates at a frequency band between 3.400 GHz and 8 GHz, and said second band is in the Ku frequency band;
a plurality of remote stations each including a remote server having a processor, a remote transmitter operating on said second band frequency, a remote receiver operating on said first band frequency, and a hybrid antenna including an antenna dish, said antenna operating on both of said first and second band frequencies;
a geostationary communications satellite; and
wherein said hub station is adapted to instruct said remote server using said first band frequency to either increase or decrease the output power of said remote transmitter; and
modifying the output power level of the remote transmitter using said remote server.

Abstract
A hybrid satellite communication system in which a hub station transmits signals to remote stations through a satellite at a relatively low frequency which is unaffected by weather effects and in which the remote stations transmit signals to the hub station at a relatively higher frequency which enables the use of more economical equipment at the remote stations. The hub station senses the signal quality or strength received from each remote station and transmits power control signals to remote stations with poor signal strengths to cause such remote stations to increase their output power to overcome weather effects. The power control signals are transmitted on the lower frequency to prevent the power control signals from being masked by the weather effects.

10. A method of satellite-based communication, comprising the steps:
-
providing a geostationary satellite; providing a hub station including a hub transmitter operating on a first band frequency, a hub receiver operating on a second band frequency, and a hub server; wherein said first band operates at a frequency band between 3.400 GHz and 8 GHz, and said second band is in the Ku frequency band; providing a remote station including a remote server having a processor, a remote transmitter operating on said second band frequency, a remote receiver operating on said first band frequency, and a hybrid antenna including an antenna dish, said antenna operating on both of said first and second band frequencies; transmitting information on said first band frequency from said hub station to said geostationary satellite using said hub transmitter, and further transmitting that information from said geostationary satellite to said remote station hybrid antenna; receiving information on said second band frequency from said geostationary satellite at said hub station using said hub receiver; monitoring the output power of the remote transmitter with said hub server; providing instructions from said hub server to said remote server using said first band frequency; and modifying the output power level of the remote transmitter using said remove server. - View Dependent Claims (11, 12, 13, 14, 15)
