Abstract: Network hardware devices organized in a Wireless mesh network (WMN) in which the network hardware devices cooperate in distribution of content files to client consumption devices without Internet connectivity are described. One mesh network device includes a housing with a first sector defined by a first recessed region between a first reflective wall, a second reflective wall, and a third reflective wall, and a second sector defined by a second recessed region between a fourth reflective wall, a fifth reflective wall, and a sixth reflective wall. A first antenna, such as a phased array dipole antenna, is disposed inside the first recessed region. A first radio, which is coupled to the first antenna, causes the first antenna to radiate electromagnetic energy in a first frequency range and the first, the second, and the third reflective walls collectively reflect the electromagnetic energy, radiated by the first antenna, in a first direction away from the housing.

Abstract: Technology for a bi-directional radio frequency front-end (RFFE) architecture with high selectivity performance is described. One RFFE has a first mixer that receives a LO signal from the LO circuit and a transmit (TX) signal, having a first frequency, from a transmitter and produces a down-converted TX signal for channel bandwidth filtering, the TX signal having a second frequency that is lower than the first frequency. A programmable filter circuit, in response to a selection signal, filters the down-converted TX signal according to a selected channel bandwidth. The second mixer receives the LO signal from the LO circuit and a channel-filtered TX signal from the programmable filter circuit and produces an up-converted TX signal having the first frequency. The power amplifier amplifies the up-converted TX signal to produce an output TX signal to cause an antenna to radiate electromagnetic energy in the selected channel bandwidth.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a single radio frequency (RF) feed and a folded monopole element coupled to the single RF feed. The folded monopole element is an integrated WAN/GNSS antenna that receives electromagnetic energy in a first frequency band and receives electromagnetic energy in a second frequency band. The first frequency band is a wireless area network (WAN) frequency band and the second frequency band is a global navigation satellite system (GNSS) frequency band. The apparatus further includes an impedance matching circuit coupled to the single RF feed. The impedance matching circuit includes a diplexer to extract out GNSS frequency signals received by the folded monopole element from WAN signals received by the folded monopole element.

Abstract: Technologies directed to sectorized analog beam searching are described. One method includes a first wireless device receiving a first destination address of a second wireless device, a first angle value corresponding to a first direction, and a second angle value corresponding to a second direction. The first wireless device generates a first signal beam transmitted in the first direction and spanning a first geographic region and receives an RSSI value corresponding to the first signal beam. The first wireless generates a second signal beam transmitted in the second direction and spanning a second geographic region and receives a second RSSI value corresponding to the second signal beam. The first wireless device determines that the first RSSI value is greater than the second RSSI value. The first wireless device determines, using a third signal beam a third angle value corresponding to a third direction located within the first geographic region.
