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.

A single-antenna device includes a single antenna, at least one processor, and at least one memory. The single-antenna device is operable to receive a signal including at least one frame. Each of said frame includes a repeating portion. The single-antenna device determines a difference of phase and amplitude of the repeating portion and further determines whether the signal is transmitted from a trusted source based at least in part on the difference of phase and amplitude of the repeating portion.

Methods of pairing devices wirelessly that include matching received-signal-strength information regarding signal-strength patterns received by differing devices desired to be paired. In some embodiments, signal-strength patterns are based on a user moving an object so as to intentionally create multipath Fresnel-zone propagation disturbances. During pairing, the devices exchange their received-signal-strength information with one another and compare the received-signal-strength information that they receive from another device to the received-signal-strength information that they generated themselves based on the multipath Fresnel-zone propagation disturbances. When the two sets of receive-signal-strength information substantially match one another, the devices determine the presence of a trusted relationship. Methods for assisting with the wireless pairing are also disclosed. Disclosed methods can be encoded in software/firmware, and such software/firmware can be stored in devices desired to include disclosed wireless pairing functionality.

Apparatus and method securely transfer first data from a source device to a target device. A wireless signal having (a) a higher speed channel conveying second data and (b) a lower speed channel conveying the first data is transmitted. The lower speed channel is formed by selectively transmitting the wireless signal from one of a first and second antennae of the source device based upon the first data. The first and second antenna are positioned a fixed distance apart and the target device uses a received signal strength indication (RSSI) of the first signal to decode the lower speed channel and receive the first data.

Embodiments herein provide methods and apparatus for monitoring and/or protecting property or other area is presented. Aspects of invention provide devices, software, systems, and methods for property and area monitoring that detect the presence of wireless devices on or over a property or in a particular geographical area. In some embodiments the detected wireless device and/or owner of a detected device can be identified. Embodiments provide methods and system for detection of wireless devices, identifiers, record time and duration that detected device was active on a property or within an area, record and transmit information to remote storage, and/or alert authorized individuals of activity within a monitored area. Embodiments of the invention allow systems and methods to work independent or with remote sensors to perform pre-programmed functions upon detection of a wireless device. Embodiments present a method for mobile configuration for scanning an area.
