Patent number: 11901934Abstract: An apparatus and method for hopping across frequencies in a transmission medium. A communication link is established between multiple devices over a communication medium using a default frequency resource. Signaling information is detected for frequency resources available on the communication medium, and values associated with the signaling information are stored within a logging table. The communication link is monitored for errors and a new frequency resource is selected from the logging table to maintain the communication link, if the errors exceed a predetermined threshold.Type: GrantFiled: December 30, 2021Date of Patent: February 13, 2024Assignee: Hughes Network Systems, LLCInventors: Emanuel Harrington, Lekha Panneer Selvam, Yong Kang Yuan

Patent number: 11831395Abstract: 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).Type: GrantFiled: December 23, 2021Date of Patent: November 28, 2023Assignee: Hughes Network Systems, LLCInventors: Yong Kang Yuan, Kevin Wong Tat, Emanuel Harrington

Patent number: 10739464Abstract: A satellite modem, a GPS device, and a method are provided. The satellite modem requests current location information from a GPS device and waits no more than a preconfigured amount of time to receive the current location information. When the satellite modem receives the current location information, the satellite modem determines whether the current location information indicates a location in which the satellite modem is authorized to operate. When the satellite modem determines that the current location information indicates a location in which the satellite modem is not authorized to operate, the satellite modem performs at least one action from a group of actions including preventing the satellite modem from operating normally, permitting the satellite modem to operate with a reduced functionality, and transmitting a message to a network management center indicating that the satellite modem is not located at an authorized location.Type: GrantFiled: July 17, 2015Date of Patent: August 11, 2020Assignee: Hughes Network Systems, LLCInventors: Emanuel Girard Harrington, Dillon James Nichols, Yong Kang Yuan

Patent number: 10079637Abstract: A very small aperture terminal (VSAT) installation tool is provided having the ability to measure cable loss along an interfacility link (IFL) between an outdoor unit and an indoor unit of the VSAT. Radio frequency (RF) signals can be transmitted from the indoor unit to the outdoor unit, where the RF signals are intercepted along the IFL prior to reaching the outdoor unit, and the output power is determined. The determined output power is compared to an expected output power at the indoor unit. The delta between the determined output power and the expected output power can be used to adjust the power of the indoor unit such that the outdoor unit can operate without reaching its compression point.Type: GrantFiled: July 18, 2016Date of Patent: September 18, 2018Assignee: Hughes Network Systems, LLCInventors: Emanuel Girard Harrington, George Eapen, Yong Kang Yuan

The delta between the determined output power and the expected output power can be used to adjust the power of the indoor unit such that the outdoor unit can operate without reaching its compression point. The determined output power can be extrapolated based upon measured of the output power performed over a range of frequencies at which the indoor unit operates.Type: GrantFiled: June 27, 2017Date of Patent: May 29, 2018Assignee: Hughes Network Systems, LLCInventors: Liming Qin, Yong Kang Yuan, Bryan Gillespie, Yiqing He

Patent number: 9515860Abstract: Systems and methods provide a receiver design capable of both wideband (high symbol rate) and narrowband (low symbol rate) operations requirements without compromising narrowband performance. Moreover, such a receiver design can be very low cost, and eschewing the need for any expensive and/or specialized elements. A receiver configured in accordance with various embodiments utilizes a fully integrated tuner in which narrowband filters are configured to be bypassable when in wideband (high symbol rate) mode in favor of fixed wideband filters. Additionally, an analog-to-digital converter (ADC) can be implemented with digital gain for wideband operation, as well as digital data bit mapping to accommodate industry standard application-specific integrated circuits (ASICs) interfaces, such as from a 12 bit ADC core to an 8 bit digital interface.Type: GrantFiled: December 30, 2014Date of Patent: December 6, 2016Assignee: Hughes Network Systems, LLCInventors: George Eapen, Yong Kang Yuan, Emanuel Harrington
