A non-invasive analyte sensor that includes one or more noise reduction components provided on the receive and/or transmit components to reduce extraneous radio frequency noise. A noise reduction component can be provided on the exterior of an electrical conductor that connects the receive antenna with the receive circuitry to suppress extraneous radio frequency noise that is generated on the exterior of the electrical conductor. The noise reduction component can be any type of noise reduction device that achieves such radio frequency noise suppression. In one embodiment, the noise reduction component can be a choke.

The inside antenna is connected between the outside antenna and the wireless communication module such that all signals received and transmitted by the outside antenna are received and transmitted through the inside antenna.

Disclosed are apparatus and a method for receiving and transmitting radio frequency signals by a vehicle (8). The method comprises: providing a transceiver module (28), the transceiver module (28) being located on board the vehicle (8) and comprising a plurality of transceivers (40-56), each transceiver (40-56) being configured to operate within a different respective radio frequency band; receiving, by a first transceiver, a first radio frequency signal having a first frequency and a first waveform; determining, using the first frequency and first waveform, by a communications management module (36) located on board the vehicle (8), a second frequency and a second waveform, the second frequency being in a different frequency band than the first radio frequency signal, the second waveform being different to the first waveform; and transmitting, by a second transceiver, a second radio frequency signal having the second frequency and the second waveform.

In a radio frequency module, the first inductor is disposed on the first principal surface of the mounting board and located on the first reception path through which a first reception signal of a first frequency passes, on an input side of the first low noise amplifier. The second inductor is disposed on the first principal surface of the mounting board and located on the second reception path through which a second reception signal of a second frequency lower than the first frequency passes, on an input side of the second low noise amplifier. The radio frequency component is disposed between the first inductor and the second inductor. A distance between the first inductor and the shielding layer is greater than a distance between the second inductor and the shielding layer. The first inductor overlaps the first low noise amplifier in a thickness direction of the mounting board.

Architectures and techniques are presented that can provide point-to-point analysis to generate an improved signal strength prediction (SSP) based on, e.g., earth surface image data processing and analysis to draw conclusions of line of sight (LOS) along the propagation path between a BTS or another AP transmitter and CPE receiver. For example, USGS image data and/or elevation data of locations are identified to correspond to signal propagation between the transmitter and receiver can be analyzed for LOS signal quality at a fixed location, in addition to the statistical model prediction of the RF signal quality. As a result, foliage or terrain that obstructs the LOS can be identified and utilized to improve SSP by eliminating the additional pathloss due to LOS obstructions. Such can provide a significant improvement to SSP results that are conventionally predicted by statistical models rather than a point-to-point analysis.

Apparatuses that provide for secure wireless communications between wireless devices under cover of one or more jamming signals. Each such apparatus includes at least one data antenna and at least one jamming antenna. During secure-communications operations, the apparatus transmits a data signal containing desired data via the at least one data antenna while also at least partially simultaneously transmitting a jamming signal via the at least one jamming antenna. When a target antenna of a target device is in close proximity to the data antenna and is closer to the data antenna than to the jamming antenna, the target device can successfully receive the desired data contained in the data signal because the data signal is sufficiently stronger than the jamming signal within a finite secure-communications envelope due to the Inverse Square Law of signal propagation. Various related methods and machine-executable instructions are also disclosed.
