  • Patent number: 9866363
    Abstract: A method for coordinated wireless network management applicable to overlay network access points. The method includes sending, from an overlay access point of a plurality of overlay access points to a coordinator device, wireless operational parameters characterizing operation of the one of the plurality of overlay access points. The overlay access point receives suggested operational information provided by the coordinator device. The suggested operational information causes modification of a perceived value of at least one operational parameter of the one of the plurality of overlay access points wherein the perceived value is different from an actual value of the operational parameter. The method further includes adjusting an operational mode of the overlay access point based upon the perceived value. The adjusting may be further based at least in part upon a negotiation of wireless access parameters between the overlay access point and one or more local wireless devices.

The process of determining the OTFS transmission waveform may include, for example, receiving, from the IOT manager device, the 2D channel state information and storing it within a memory of the IOT device. Alternatively, at least one OTFS pilot transmission may be received from the IOT manager device and the 2D channel state information determined using the OTFS pilot transmission.

  • Patent number: 9294315
    Abstract: A method of data transmission including arranging a set of data elements into an original data frame having a first dimension of N elements and a second dimension of N elements, where N is greater than one. The method includes transforming the original data frame in accordance with a transformation matrix to form a first transformed data matrix having at least N2 transformed data elements wherein each of the transformed data elements is based upon a plurality of the data elements of the original data frame and wherein a first dimension of the first transformed data matrix corresponds to a frequency shift axis and a second dimension corresponds to a time shift axis. A permuted data matrix is formed by permuting at least a portion of the elements of the first transformed data matrix so as to shift the at least a portion of the elements with respect to the time shift axis.

  • Patent number: 8879378
    Abstract: A wireless combination time, frequency and spectral shaping communications method that transmits data in convolution unit matrices (data frames) of N×N (N2), where generally either all N2 data symbols are received over N spreading time intervals (each composed of N time slices), or none are. To transmit, the N2 sized data frame matrix is multiplied by a first N×N time-frequency shifting matrix, permuted, and then multiplied by a second N×N spectral shaping matrix, thereby mixing each data symbol across the entire resulting N×N matrix (TFSSS data matrix). Columns from this N2 TFSSS data matrix are selected, modulated, and transmitted, on a one element per time slice basis. At the receiver, the replica TFSSS matrix is reconstructed and deconvoluted, revealing the data. The method can accommodate multiple users at once, can adapt to changing channel conditions, and is particularly useful for coping with channel impairments such as Doppler shifts.

  • Patent number: 8826359
    Abstract: System and method to extend the upstream data capacity of an HFC CATV system by extending a “shadow” optical fiber network deeper into the various CATV cable neighborhoods, with coax fiber terminals (CFT) spaced roughly according to the distribution of CATV active devices such as RF amplifiers. The CFT can intercept local upstream data from various neighborhood sub-regions and transform this upstream data into upstream optical data, thus relieving upstream data congestion in the 5-42 MHz CATV frequency region. The system can produce an order of magnitude improvement in upstream capability, while maintaining high compatibility with legacy HFC equipment. The CFT may exist in multiple embodiments ranging from low-cost “dumb” CFT to sophisticated CFT that can additionally provide GigE to the home (GTTH) service. Methods to maintain good compatibility with legacy CMTS devices, and methods to utilize DOCSIS MAP data for more efficient data transmission are also discussed.

  • Patent number: 8547988
    Abstract: A wireless combination time, frequency and spectral shaping communications method that transmits data in convolution unit matrices (data frames) of N×N (N2), where generally either all N2 data symbols or elements are received over N spreading time intervals (each composed of N time slices), or none are. To transmit, each data element is assigned a unique waveform which is derived from a basic waveform of duration N time slices over one spreading time interval, where each basic waveform has a data element specific combination of a time and frequency cyclic shift. At the receiver, the received signal is correlated with the set of all N2 waveforms previously assigned to each data element by a transmitter for that specific time spreading interval, producing a unique correlation score for each one of the N2 data elements. The scores are summed over each data element, and this summation reproduces the data frame.

  • Patent number: 8509032
    Abstract: A system and method to optimize the overall power output of a photovoltaic solar array. The solar panels are connected to software adjustable power optimizing devices, which in turn are connected to a mesh network with individual router devices. The individual router devices will send and receive data packets by creating or detecting vibrations in a solid vibration conducting media (such as the solar power wiring) that connects the individual photovoltaic solar panels. Often at least one centralized control device is used to periodically request sensor data packets from the individual router devices and solar panels. The centralized control device will typically compute the proper adjustments for the individual adjustable power optimizing devices that will optimize the overall power output from the photovoltaic solar array. The control device will then send adjustment data packets back to the individual router devices through the mesh network, thus optimizing overall power output.
