  • Publication number: 20190124661
    Abstract: Methods and apparatuses providing a visual metric of the efficiency of a network of devices communicating through a wireless access point (AP). These apparatuses and methods may also determine and display pseudo-dynamic error vector magnitude (EVM) information for a network of wireless stations, including displaying a pseudo-dynamic constellation diagrams using EVM information. These methods and apparatuses may transmit a plurality of sounding packets from each of one or more radio devices different modulation types (e.g., BPSK, QPSK, 16QAM, 64QAM, 256QAM and 1024QAM), and receiving at least some of the sounding packets at a second radio device (e.g., an access point) and determining EVM information from the received sounding packets, and displaying (or providing for display) a constellation diagram including pseudo-dynamic EVM information that is a constrained approximation of actual EVM information.

  • Patent number: 10194328
    Abstract: Generation and use of geographic databases of frequency spectral information within an operating frequency band. Described herein are methods of making databases of geospectral information and using these databases to optimize performance of wireless networks. For example, a network of wireless radio devices that monitor the frequency spectrum of the operating frequency band may provide this geographically marked information to a central database to create a database of geospectral frequency information. This geospectral frequency information may be used to characterize, optimize or modify a network of wireless radio device, or to modify an individual wireless radio device.

  • Patent number: 10149337
    Abstract: Methods, apparatuses, and systems for transmitting information between nodes in a point-to-point wireless communication network is disclosed. One method includes constructing, by a sector of a transmitting node, a packet including data that is to be transmitted to a receiving node in the wireless network, wherein the constructed packet includes a short training field, a channel estimation field, a header field, and a data payload, and transmitting by the sector of the transmitting node, a jamming code before the short training field of the constructed packet, thereby reducing a likelihood that the receiving node will decode a different short training field of an interfering packet before the receiving node decodes the short training field of the constructed packet.
