  • Patent number: 8644271
    Abstract: A wireless mesh communication protocol that dynamically assigns communication time-slots and frequencies to mesh nodes. A first node is established as a PC that sequentially polls other nodes. A second node responds at a predetermined time with information that includes database records, and then a third node responds similarly. The second node is then established as the PC and the first node is polled during dynamically allocated time-slots and on a frequency that depend on the second node's database records. The third node is then established as a PC and acts similarly. In both cases the first node responds by sending information and data records. The first node is then re-established as the PC. The first node then polls the second and third nodes at times and frequencies that depend on the first node's database records.

  • Patent number: 7356043
    Abstract: Network channel access protocol is disclosed. More particularly, a distributed, locally determined, channel access protocol that adapts to load, avoids interference and controls access by a group of nodes to a set of shared channels is disclosed. Shared channel space is divided into a number of communication slots that are repeated at a predetermined interval. Permission to use a slot to communicate between any two nodes is dynamically adjusted by the channel access protocol, which locally: (i) estimates load to neighboring nodes; (ii) allocates or deallocates slot usage to adapt to load and avoid interference; and (iii) asserts and advertises slot usage within an interference area about itself.

  • Patent number: 7053853
    Abstract: A planar antenna that facilitates directional communication to a mesh network. The antenna is housed in a relatively small, planar package that can easily be attached to a window pane to enable the antenna to communicate with a neighboring rooftop mounted node of the mesh network. The package contains an M by N element phased array, where M and N are integers greater than one. The array is driven by microwave signals supplied from a P-angle phase shifting circuit, where P is an integer greater than one. Thus, the antenna synthesizes a single main beam and the antenna's main beam can be electrically “pointed” in one of P directions. In one embodiment of the invention, the array comprises 40 physical elements (8×5 elements) and has three selectable directions (i.e., the phase shifters provide +90, 0 and ?90 degree shifts that move the beam left 45 degrees, center and right 45 degrees).

  • Patent number: 5315583
    Abstract: A radio broadcasting system for a composite signal consisting of a frequency modulated (fm) analog signal and a multicarrier modulated digital signal is provided which is resistive to multipath degradation. The fm signal and the digital multicarrier modulated signal are fully coherent. The digital signal uses a plurality of carriers having a maximum amplitude at least 20 dB below the unmodulated fm signal. The multicarrier modulated signal is phase locked to a recovered analog fm pilot tone in the composite baseband spectrum of the fm signal which is at least 20 dB above the multicarrier modulated signal, which enables rapid and reliable acquisition of signal for coherent detection. In a specific embodiment the multicarrier modulated signal is a synthesized vector-modulated signal which is a quadrature phase shift keyed (QPSK) modulated set of synthesized carriers each occupying 9.5 kHz of spectrum replicated twenty-one times within a 199.5 kHz bandwidth with no more than two bits per vector.

  • Patent number: 5278826
    Abstract: A radio broadcasting system is provided for transmitting and receiving through free space a composite signal consisting of a frequency modulated (fm) analog signal and a multicarrier modulated digital signal which is especially adapted to be resistive to multipath degradation. The fm signal and the digital multicarrier modulated signal are fully coherent. Further according to the invention, the digital signal comprises a plurality of carriers having a maximum amplitude at least 20 dB below the unmodulated fm signal and preferably, 30 dB below the analog signal. The multicarrier modulated signal is phase locked according to the invention to the recovered analog fm pilot tone at 19 kHz in the composite baseband spectrum of the fm signal which is at least 20 dB above the multicarrier modulated signal, which enables rapid and reliable acquisition of signal for coherent detection.
