Abstract: A system is disclosed for adaptively controlling transmission rate between first and second terminals. The system comprising a controller and a transmit unit. The controller comprising a computing unit, a storage unit and a memory unit. The transmit unit is to transmit signals over a communication link from the first terminal to the second terminal and the computing unit is adapted to receive indication of a signal-to-noise-ratio (SNR) of transmission in the communication link and to execute program stored in the memory unit to change the transmission rate of the transmit unit in response to changes in the SNR.

Abstract: A mobile terminal, operational both to receive and transmit, may comprise a mobile antenna and an antenna controller that may be configured to control the mobile antenna at least for keeping it pointed towards the satellite, e.g. as the mobile terminal and/or the satellite move. Disclosed is a method that may be used by the antenna controller for optimizing the pointing of the mobile antenna, the method may be based on assessing both the reception quality and the transmission quality. This method may be used for overcoming degradation, mainly to transmission quality, that may result from squints between an optimal reception direction and an optimal transmission direction associated with the mobile antenna.

Abstract: An example method includes estimating whether a collision occurred between a plurality of wide band response signals, the wide band response signals being responsive to a first interrogation signal transmitted by a first reader; when the collision is estimated to have occurred and the first reader received a first response from a particular tag, transmitting, by the first reader, a second interrogation signal, the second interrogation signal initiating a communication session between the reader and the particular tag; and transmitting, by the first reader, an acknowledgement packet to cause the tag to refrain from responding to a command during the communication session; and a second reader to refrain from interrogating the particular tag during the communication session.

Abstract: The Very Light Readers of the present invention are based on an augmented Tag circuit with a preferred embodiment including at least one VLSI chip integrating a UWB front end, digital transceiver, and possibly an internal controller; a UWB Antenna; a power supply; a controller configured to implement the Media Access Control protocol of the system; a Communication Interface subsystem for connection to the system network and a clock source. Also described is a system capable of reducing collision occurrence in a network for communicating between multiple readers and a plurality of RF Tags. Tags are configured to receive interrogation signals and transmit response signals. Readers are configured to transmit interrogation signals, receive response signals, estimate the quantity of responses received to an interrogation, determine the round trip delay time of each response and estimates whether a collision between responses has occurred. If so, the Reader transmits an additional interrogation signal.

Abstract: Embodiments of the present invention relate generally to packetization techniques for satellite transmission of data, such as telephony data. Some embodiments use the MPEG2 standard in connection with the ETSI DVB data piping profile for arranging the data. Embodiments also relate to method for receiving, demultiplexing and managing incoming telephony data to support a variety of telephony applications including voice, facsimile, Internet and other data.
