Systems and methods of performing location tracking with ultra wideband (UWB) are provided. The system includes a network formed by base stations and tags. In operation, the system configures multiple Time Division Multiple Access (TDMA) slots within a predetermined time frame. The TDMA slots include a clock calibration packet (CCP) slot, personal area network (PAN) identifier request and response slots, and TDMA tag slots. In the CCP slot, clock synchronization is performed among the base stations and the tags. In the PAN identifier request and response slots, the base stations receive reservation requests from the tags, and send correspond reservation responses. In each TDMA tag slot, the base stations listen to ranging requests from each tag, and send corresponding ranging responses with corresponding timestamps indicating the corresponding TDMA tag slot for each tag. Each tag only wakes up during the corresponding TDMA tag slot, thus achieving low power consumption.

A multi-radio border router for synchronizing communications of multiple border router radios is provided. For example, the border router includes a border router component connected to each of the plurality of border router radios. The border router component configured for selecting one of the plurality of border router radios as a master radio and assigning channel offset parameters for each of the plurality of border router radios. The master radio is configured for broadcasting synchronization beacons based on which the non-master radios synchronize their respective clocks with that of the master radio. After the synchronization, each of the border router radios communicates with endpoints associated therewith according to a channel hopping pattern modified by applying a channel offset determined based on the channel offset parameters assigned to the respective radio.

A master-slave system for communication over an ultra-wideband radio connection is proposed. The master-slave system comprises at least one slave device and one master device, wherein the slave device and the master device are configured to communicate over the ultra-wideband radio connection. The master device is configured to generate and transmit a request message to the slave device over a first channel of the ultra-wideband radio connection. The slave device is configured to receive the request message over the first channel of the ultra-wideband radio connection, generate at least one response message based on the request message, and transmit the at least one response message to the master device over the first channel of the ultra-wideband radio connection, and the master device is configured to receive the at least one response message. Further, the master device is configured to classify the first channel of the ultra-wideband radio connection as suitable or unsuitable for data transmission based on the at least one received response message and to transmit further messages on the first channel of the ultra-wideband radio connection or to change to another channel of the ultra-wideband radio connection based on the classification.

Systems and methods for avoiding interference are provided. Such systems and methods can include receiving wireless network information from a first access point, the wireless network information identifying any channels used by any WiFi networks detected by a first access point, identifying any second information channel sequences used by any second access points located within a predetermined distance of the first access point, identifying and allocating a first information channel sequence to be used by the first access point so that no channels in the first information channel sequence overlap with any of the channels used by the WiFi networks or with the second information channel sequences, identifying and allocating a first operating channel sequence to be used by the first access point based on the first information channel sequence, and transmitting the first information channel sequence and the first operating channel sequence to the first access point.

Logic may transmit or receive communications that hop frequencies in response to trigger events across a large bandwidth. Logic may generate a communication with a contiguous or non-contiguous bandwidth based upon frequency segments of 80 MegaHertz (MHz) and/or 160 MHz. Logic may generate a communication with a contiguous bandwidth of 480 MHz. Logic may generate a communication with a non-contiguous bandwidth of 480 MHz. Logic may transmit or receive communications with a 480 MHz bandwidth that hop across a 3 GigaHertz (GHz) bandwidth of frequency channels. Logic may determine a channel-hopping pattern. Logic may hop frequency channels after each link transmission. Logic may hop channels after a fixed time interval. And logic may hop frequency channels in response to another triggering event.

Technologies directed to a process of establishing a wireless connection between two devices with out-of-band transport assistance are described herein. In one method, a first device scans for a first message via a first radio. The first message includes information that a second device is using either a first or a second set of frequencies of a page hopping sequence. The first device repeatedly sends, via a second radio, a second message according to only the first or second set specified in the first message. The first device receives, via the second radio at a first frequency of the first or second set, a third message from the second device, via the second radio at the first frequency, a third message comprising additional information that establishes the wireless connection between the first device and the second device via the second radio.
