Abstract: A network node and a method for controlling a wireless network are disclosed, wherein the network node includes a receiving device configured co receive data packets from one or more other network nodes of a plurality of network nodes; one or more processors configured to determine two or more network nodes of the plurality of network nodes to which the network node may forward data packets such that a number of the determined two or more network nodes is greater than a predefined first threshold value; and a transmitting device configured to forward the received data packets to the determined two or more network nodes of the plurality of network nodes.

Abstract: A wireless communication is proposed that utilizes a large available bandwidth (e.g., 10-100,000 MHz) and employs a combination of frequency shifting (from an input RF signal to an IF signal) and frequency hopping from one IF frequency value to another within the available bandwidth. The combination of frequency shifting and frequency hopping adds a level of noise mitigation moving the transmission frequency as a function of time (and avoiding frequencies known to be subject to noise). By its nature, the addition of frequency hopping frustrates the ability of outsiders to access transmissions. A map of frequencies to be used may be delivered to both the transmitter and receiver via a separate command/control signal path. Alternatively, a transmitter may develop the map and forward it to the receiver. The frequency hopping sequence is preferably a randomly-generated sequence that uses the entire available bandwidth.

Abstract: An application-specific wireless communication network for use in an industrial environment based on parameters defined by the IEEE 802.11 standard, modified by providing software-defined control of an assigned operating frequency band and software-defined control of the channel size, allowing the channel size to be relatively small as appropriate for the particular industrial application. The application-specific wireless communication network further controls other parameters defined by the standard to configure at least optimum transmitter power, receiver sensitivity, transmission latency, and ACK-retransmit to values appropriate for the specific industrial application.

Abstract: An apparatus for shared spectrum access (referred to at times hereinafter by the acronym “ASSA”, or more generally, as a “gateway device”) is configured to work with one or more private networks, providing control of operating parameters such as the assignment of a specific frequency band (channel), maximum level of transmission power at an assigned channel, and/or even the ability to use a shared spectrum assignments, updating as need be. By virtue of provisioning end-user devices (EUDs) with software-defined transceivers, the ASSA may function to broadcast “operation parameters” (i.e., assigned frequency band and maximum transmission power) to all EUDs within its range. The EUDs may be fixed or mobile devices.

Abstract: A method and apparatus decode packetized data in the presence of packet erasures using a finite sliding window technique. A decoder receives packets containing uncoded and coded symbols. When a packet with a coded symbol is received, the decoder determines whether a packet sequence number is within a sliding window of w consecutive sequence numbers that are no greater than a decoder sequence number, where the number w is fixed prior to encoding. When this is the case, the decoder decodes the coded symbol into one or more of the w input symbols using the coefficient vector. Decoding may use a forward error correcting (FEC) window within the finite sliding window. Decoding also may use a technique of Gaussian elimination to produce a “shifted” row echelon coefficient matrix.
