An ultra-wideband (UWB)-enabled payment acceptance system can include a UWB anchor and a terminal device. The UWB anchor identifies UWB-enabled devices within a vicinity; and in response to receiving an indication of an intent to perform a payment transaction from a particular UWB-enabled device, the UWB anchor establishes a secure communication channel with the particular UWB-enabled device. The terminal device, via the UWB anchor, communicates transaction related information over the secure communication channel to the particular UWB-enabled device and receives a transaction payload from the particular UWB-enabled device over the secure communication channel. A UWB-enabled device includes a processor, storage, a battery, and a UWB chip. Instructions can be stored in the storage of the UWB-enabled device that when executed by the processor direct the UWB-enabled device to perform various processes supporting frictionless transactions, such as with respect to the UWB-enabled payment acceptance system.

A method for proximity detection and ranging with neighboring devices is described here. The method includes identifying, by a processor of a first tag, a second tag from a group of tags within a predefined range of the first tag. The method further comprises initiating, by the processor, transmission of a packet to the second tag in the group of tags identified within the predefined range. The method further comprises, in response to the transmission of the packet, receiving, by the processor, a response packet from the second tag. The method includes in response to receiving the response packet, determining a tag distance between the first tag and second tag. The method includes determining that the tag distance associated with the second tag is less than a predefined distance, generating, by the processor, an alarm or notification to the first tag indicating that the predefined distance is crossed.

Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Such UWB systems through their receivers may operate in the presence of interfering signals and should provide for robust communications. Accordingly, an accurate and sharp filter that operates at low power is required and beneficially one that does not require a highly accurate power heavy clock. Further, many UWB applications require location and/or range finding of other elements and it would therefore be beneficial to provide a UWB based range finding and/or location capability removing the requirement to add additional device complexity and, typically significant, power consumption.

A mobile device can wirelessly connect, using transceivers, to a medical item and a wristband worn by a user. The mobile device includes a software application enabling a user to input distance thresholds. The wristband can also include a software application enabling a user to input distance thresholds. Both the mobile device application and the wristband application can monitor signals between the medical item and wristband. In another system, a medical item distance alert system can include a plurality of medical items. In another system, a mobile device is not in communication with the wristband or medical items. The wristband software application can monitor signals between medical items and provide alerts in the absence of another mobile device. Preferably, ultra-wideband (UWB) and Bluetooth transceivers can be implemented to provide accurate distance estimates with low power usage.

An example method includes sensing, by a sensor of a mesh node, first sensor data; receiving, at the mesh node, second sensor data from an origin node, wherein the mesh node and the origin mode are different nodes; and in response to receiving an indication that the origin node is obstructed, transmitting, by the mesh node, the second sensor data.
