Systems and methods for system for tag polling are disclosed herein. An example system includes: a tag associated with an asset; an anchor configured to poll the tag at a first transmission rate and determine an angle-of-arrival (AOA) based on signal data received from the tag; and a server communicatively coupled with the anchor. The server may be configured to: receive first information corresponding to the tag, the first information being indicative of one or more first instances where the anchor polls the tag at a second transmission rate that is different from the first transmission rate. The server may further be configured to receive, from the anchor, a tag listing that includes the tag, determine a first instance occurrence for the tag based on the first information, and transmit a request to the anchor that causes the anchor to poll the tag at the second transmission rate.

Data capture system and method for object dimensioning

An image processor provides a combined image of an object from first and second cameras. The image processor receives a first image from a first camera and a second image from a second camera. The first and second images each include a field of view and metadata associated with the image. The image processor determines whether a combined image of the first and second images will be viewed by a person or a machine. If the combined image is to be processed by a machine, the first and second metadata are included with the combined image and sent to the machine. If the combined image is to be viewed by a person, the combined image includes a subset of the metadata so that the image is not too large or too cluttered.

A method and circuit for mitigating RFI in an electronic device that occurs while the device is in a low power mode utilizes one or more antenna elements in the device to receive RF energy. When the RF energy is sufficiently high that it could affect signal states in the device while in the low power mode, the device transitions from the low power mode to an active mode and begins an RFI mitigation process to ensure signal states and other circuit operations in the device are not changed by the RFI.

In a network comprising a plurality of channels, at least two channels are operating at different frequencies. The fixed network equipment (FNE;) identifies a plurality of channels present at a serving site and classifies each channel into one of a plurality of bandwidth groups. All the channels in a given bandwidth group have common roaming characteristics. The FNE periodically broadcasts information relating to at least one channel in each bandwidth group present at the serving site. The FNE further identifies least one channel present at an adjacent site. Each channel present at the adjacent site is also classified in one of the plurality of bandwidth groups. The FNE broadcasts information on loading for each bandwidth group present at the adjacent site.

The packet is then split into a plurality of segments () where an RLA is used () to determine the optimum format of the packet. The plurality of segments is then sent to a channel encoder for FEC encoding and symbol mapping () at a rate selected by the RLA.

A method and system for synchronizing scan opportunities in a mobile communications system. Time slots are sent between a mobile subscriber and an associated base station wherein the mobile subscriber corresponds to a scan group. The number of time slots sent between the mobile subscriber and the associated base station is counted. Based upon the count, the scan group of the mobile subscriber, a scan rate, and a scan opportunity divisor, a scan opportunity is determined. If it is a scan opportunity, a scan is performed of a neighboring base station.
