摘要： A satellite antenna system (30) that employs a small phased antenna array (46) acting as a redundant antenna. Because the phased array (46) is steerable, it can be selectively directed to any of the cells (16) on the Earth (12) in the event that the LNA in an antenna channel (32) fails. The phased array (46) is switched into each antenna channel (32) after the channel front end (40) where a switch (56) used to switch in the phased array (46) is after the amplification in the channel (32). Therefore, the switch (56) does not significantly affect the noise figure of the channel front end (32).

摘要： An apparatus and a method for separating a digital broadcasting signal from data transmitted using an IP network, transmits an IP packet at wire-speed by performing a comparison of an IP address in a hardware scheme without a special memory when separating Internet data and digital broadcasting data (MPEG-TS) in an IP network-based digital broadcasting signal process unit. The digital broadcasting signal separation apparatus includes a reception buffer for receiving the IP packet transmitted through a transmission media; an extractor for copying an IP header from the IP packet outputted from the reception buffer and for extracting the IP header only; a comparator for comparing the address of the IP header extracted from the IP header extractor with the address of the IP header stored in the register; a register for storing a multicast IP address value or a unicast IP address value which includes information on broadcasting channel established by the user; an IP packet path processing unit for selecting an IP packet path according to the result value of the comparison outputted from the comparator; a transmission buffer for transmitting the IP packet in order to return the IP packet from the IP packet path processing unit to the computer, in case that the result value of the comparison of the comparator is determined to be an IP address corresponding to normal Internet data; and an MPEG-TS processing unit for processing the IP packet outputted from the IP packet path processing unit, in case that the result value of the comparison of the comparator is determined to be an IP address corresponding to the digital broadcasting signal.

摘要： A method of utilizing low-data-rate wireless channels (46) in a satellite-based wireless communication network (20) detects a transmit signal (64) and determines a data type (120, 122, 124) for the transmit signal (64). A quantity of the wireless channels (46) are assigned for transmission of the transmit signal (64) in response to the data type (120, 122, 124). An inverse multiplexing system (50) selectively splits the transmit signal (64) into multiple subsectional signals for transmission over separate wireless channels (46) to facilitate the transmission of large data files and real-time video imagery over the low-data-rate wireless channels (46).

摘要： A method and apparatus is provided for the time-based provisioning of wireless devices. A network access point monitors operation of wireless devices within a service region. When provisioning logic is activated at the network access point, the access point determines if the tracked parameter (such as power on or the onset of signal transmission) of the wireless device occurs within a designated time interval from the time of the provisioning activation. If the tracked device qualifies, the network access point proceeds with provisioning the device. In one system embodiment, the network access point tracks the power on time of wireless devices. When a wireless device to be authorized is powered on, the provisioning logic at the network access point notes the power on time. The user then activates the provisioning access at the network access point, and the network access point provisions the wireless device if it is recently powered on.
