Abstract

A network device for providing configurable reference frequencies in a satellite communication system is disclosed. The network device may be any of a satellite modem, satellite transceiver, or satellite router. The network device may receive information pertaining to a type of an Outdoor Unit (ODU), determine the type of ODU based on the received information, and provide a plurality of configurable reference frequencies based on the type of the Outdoor Unit (ODU) such that the plurality of configurable reference frequencies may be used with different combinations of low noise block converters (LNBs) and block-up converters (BUCs).

Claims (37)

1. A network device for a satellite communication network, comprising:

a processor; and

a memory having instructions, which when executed by the processor, causes the processor to:

receive information pertaining to a type of an outdoor unit (ODU);

determine a type of ODU based on the received information; and

provide a plurality of configurable reference frequencies based on the type of the ODU such that the plurality of configurable reference frequencies are used with one or more combinations of low noise block converters (LNBs) and block-up converters (BUCs) associated with the ODU.

2. The network device as claimed in claim 1 , wherein the network device is any of a satellite modem, satellite transceiver, or a satellite router.

3. The network device as claimed in claim 1 , wherein the plurality of configurable reference frequencies comprises radio transmitter (TX) and radio receiver (RX) reference frequencies.

4. The network device as claimed in claim 3 , wherein the network device comprises:

a low noise oscillator that is operatively coupled with a sampling clock such that the sampling clock causes one or more Digital-to-Analog converters (DACs) to generate the plurality of TX reference frequencies for the BUCs and RX reference frequencies for the LNBs.

5. The network device as claimed in claim 4 , wherein output of the plurality of DACs are amplified by corresponding amplifiers, wherein a first amplifier corresponding to a first DAC receives, as input, TX reference control frequency through a first switch to generate TX reference frequencies, and a second amplifier corresponding to a second DAC receives, as input, RX reference control frequency through a second switch to generate RX reference frequencies.

6. The network device as claimed in claim 1 , wherein the network device comprises:

a DAC that is operatively coupled with a RF splitter such that output of the RF splitter is processed by a first amplifier to generate RX reference frequencies, wherein the first amplifier receives an input from a first switch that in turn processes a RX reference control frequency.

7. The network device as claimed in claim 5 , wherein the network device further comprises a second switch that receives the input from the RF splitter and provides output to a second amplifier that generates TX reference frequencies, wherein the second amplifier receives an input from a third switch that in turn processes a TX reference control frequency.

8. The network device as claimed in claim 6 , wherein the second switch additionally receives one or more desired TX reference frequencies as input from a fourth switch, wherein the one or more desired TX reference frequencies are generated by division of an initial frequency input generated by an oscillator.

9. A satellite modem configured in a satellite communication network, wherein the satellite modem receives details pertaining to a type of an outdoor unit (ODU), and correspondingly provides a plurality of configurable reference frequencies based on the type of the ODU such that the plurality of configurable reference frequencies are used with different combinations of low noise block converters (LNBs) on receiver (RX) side and block-up converters (BUCs) on transmitter (TX) side.

10. The satellite modem as claimed in claim 9 , wherein the satellite modem comprises a low noise oscillator that is operatively coupled with a sampling clock that provides a clock signal to one or more Digital-to-Analog converters (DACs) so as to generate the plurality of TX reference frequencies for the BUCs and RX reference frequencies for the LNBs.

11. A method for providing a plurality of configurable reference frequencies, comprising:

configuring, by a processor, a network device of a satellite communication network;

receiving, by the network device, information pertaining to a type of Outdoor Unit (ODU);

determining, by the network device, the type of ODU based on the based on the received information; and

providing, through the network device, a plurality of configurable reference frequencies based on the type of the ODU such that the plurality of configurable reference frequencies are used with different combinations of low noise block converters (LNBs) and block-up converters (BUCs).

12. The method as claimed in claim 11 , wherein the network device is any of a satellite modem, satellite transceiver, or a satellite router.

13. The method as claimed in claim 11 , wherein the plurality of configurable reference frequencies comprises radio transmitter (TX) and radio receiver (RX) reference frequencies.

14. The method as claimed in claim 13 , wherein the network device comprises:

a low noise oscillator that is operatively coupled with a sampling clock such that the sampling clock causes one or more Digital-to-Analog converters (DACs) to generate the plurality of TX reference frequencies for the BUCs and RX reference frequencies for the LNBs.

15. The method as claimed in claim 14 , wherein output of the plurality of DACs is amplified by corresponding amplifiers, wherein a first amplifier corresponding to a first DAC receives, as input, TX reference control frequency through a first switch to generate TX reference frequencies, and a second amplifier corresponding to a second DAC receives, as input, RX reference control frequency through a second switch to generate RX reference frequencies.

16. The method as claimed in claim 13 , wherein the network device comprises:

a DAC that is operatively coupled with a RF splitter such that output of the RF splitter is processed by a first amplifier to generate RX reference frequencies, wherein the first amplifier receives an input from a first switch that in turn processes a RX reference control frequency.

17. The method as claimed in claim 16 , wherein the network device further comprises a second switch that receives the input from the RF splitter and provides output to a second amplifier that generates TX reference frequencies, wherein the second amplifier receives an input from a third switch that in turn processes a TX reference control frequency.

18. The method as claimed in claim 17 , wherein the second switch additionally receives one or more desired TX reference frequencies as input from a fourth switch, wherein the one or more desired TX reference frequencies are generated by division of an initial frequency input generated by an oscillator.

19. A non-transitory computer-readable storage medium having an executable stored thereon, which when executed instructs a processor to perform a method as follows:

configuring a network device of a satellite communication network;

receiving information pertaining to a type of Outdoor Unit (ODU);

determining the type of ODU based on the received information; and

providing, through the network device, a plurality of configurable reference frequencies based on the type of the ODU such that the plurality of configurable reference frequencies are used with different combinations of low noise block converters (LNBs) and block-up converters (BUCs).

20. The non-transitory computer-readable storage medium as claimed in claim 19 , wherein the network device is any of a satellite modem, satellite transceiver, or a satellite router.
