    Abstract: A method of determining a position location of an asset tag within an indoor position location system includes filtering a history of locations of an asset tag within the indoor position location system. Such a method further includes computing, based on the history, a likelihood that the asset tag is in a predetermined room of the indoor position location system.

    Abstract: An air to ground communication system provides internet access to aircraft from ground based stations. The air to ground system shares spectrum with uplink portions of a satellite communication spectrum. Interference mitigation techniques are employed to avoid interference between the ground based communications and satellite communications. Fade mitigation techniques are employed to provide communication to aircraft at low angles of elevation in the presence of rain.

    Abstract: The present disclosure presents a method and an apparatus for communications in a non-geostationary orbit (NGSO) satellite network. For example, the method may include receiving data, at a relay node, from a first NGSO satellite of the NGSO satellite network, wherein the relay node is located at a boundary or a common beam area associated with the first satellite and a second satellite of the NGSO satellite network, and wherein the data is received at the relay node in response to identifying by the first NGSO satellite that an internet point of presence (IPP) is not available in at least one of a plurality of beams associated with the first NGSO satellite, and relaying the data from the relay node to a second NGSO satellite of the NGSO satellite network, wherein an IPP is available in at least one of a plurality of beams associated with the second NGSO satellite. As such, communications in a non-geostationary orbit (NGSO) satellite network may be achieved.

    Abstract: Transmitter and receiver units for use in an OFDM communications system and configurable to support multiple types of services. The transmitter unit includes one or more encoders, a symbol mapping element, and a modulator. Each encoder receives and codes a respective channel data stream to generate a corresponding coded data stream. The symbol mapping element receives and maps data from the coded data streams to generate modulation symbol vectors, with each modulation symbol vector including a set of data values used to modulate a set of tones to generate an OFDM symbol. The modulator modulates the modulation symbol vectors to provide a modulated signal suitable for transmission. The data from each coded data stream is mapped to a respective set of one or more “circuits”. Each circuit can be defined to include a number of tones from a number of OFDM symbols, a number of tones from a single OFDM symbol, all tones from one or more OFDM symbols, or some other combination of tones. The circuits can have equal size or different sizes. Different circuits can be used for full rate data (e.g., active speech) and low rate data (e.g., silence periods).
