CPC Class H04W

Novel tools and techniques are provided for implementing telecommunications signal relays, and, more particularly, to methods, systems, and apparatuses for implementing telecommunications signal relays using radiating closures (either aerial, below grade, and/or buried, etc.), or the like. In various embodiments, a signal distribution system, which might be disposed within a radiating closure, might receive a first communications signal. A wireless transceiver of the signal distribution system might send the first communications signal, via one or more wireless communications channels, to one or more devices that are external to the radiating closure. In some embodiments, antennas—which might comprise first antennas disposed within the radiating closure or second antennas embedded in a housing material of the radiating closure, or both—might direct the first communications signal that is sent from the wireless transceiver to the one or more devices. In some cases, IoT sensors may be implemented in the radiating closure.

A location tracking power cord and method therefore is taught in the various embodiments. The power cord includes a location module housing having a location circuit board therein. Within the location module housing, a power supply is positioned and in electrical communication with conductors extending through the cord housing. The location module housing also provides location for a communication module including a location module such as a Global Positioning System (GPS) satellite receiver and at least one cellular transceiver. In some embodiments, the power cord may be hospital grade.

Disclosed is a system including RF circuitry configured to generate an RF signal; a plurality of unit cells configured to receive the RF signal and to cause an RF energy signal having a center frequency to be present within the unit cells; and receiver circuitry configured to charge an electronic device in response to an antenna of the electronic device receiving the RF energy signal when the antenna is tuned to the center frequency and positioned in a near-field distance from one or more of the unit cells.

One example discloses a combination wireless charging and communications device, including: a series reactance; wherein the series reactance is configured to be coupled in series between an antenna and a charging circuit; wherein the series reactance is configured to conduct a charging current between the antenna and the charging circuit; a parallel reactance; wherein the parallel reactance is configured to be coupled in parallel with the antenna and a communications circuit; and wherein the parallel reactance is configured to conduct a communications voltage between the antenna and the communications circuit.

A wireless power receiver can include a magnetic substrate and a coil configured to wirelessly receive power. The coil can be formed as a conductive layer on the magnetic substrate. A connecting unit can be disposed in a receiving space of the magnetic substrate and can be connected to the coil unit.

A system has a plurality of non-linear circuit stages and an intervening linear circuit stage. An input signal is provided to a first non-linear circuit stage, and from the first non-linear circuit stage, to the linear circuit stage. The first non-linear circuit stage applies a second-order distortion to the input signal and provides the resulting signal to the linear circuit stage. The resulting signal that is output from the linear circuit stage is inverted with respect to the input signal and suitably linearly processed (attenuated or amplified). This signal is then provided to a second non-linear circuit that applies a second-order distortion and outputs a signal that has an overall reduction in second-order distortion.

In a communication system of the LPWAN type including a server and a plurality of gateways intended to make wireless communications with terminals in said communication system, the server: obtains a description of a mobility hierarchy in which mobility types are hierarchically defined; obtains a description of a mobility tree in which mobility areas are hierarchically defined, in conformity with the mobility hierarchy; obtains terrain measurements associated with each mobility area defined in the mobility tree; establishes a frequency plan on the basis of the mobility tree and terrain measurements; and configures the gateways and the terminals according to the frequency plan established.
