Disclosed are techniques for generating a positioning beacon sequence suitable for use in a wireless network that utilizes beamformed communication. More particularly, the positioning beacon sequence may be generated based on a first sequence that depends on a link identifier and does not depend on a beam index assigned to a beam used to transmit the positioning beacon in combination with a second sequence that depends on the beam index and does not depend on the link identifier. For example, the first sequence and the second sequence may be XORed to obtain the final beacon sequence, or the first sequence and the second sequence may be modulated and multiplied to obtain the final beacon sequence. Furthermore, in practice, the beacon sequence may be generated using a pseudo-random sequence generator initialized with a seed in which the link identifier and the beam index are treated as separate subcomponents.

The beacon system may include a receiving device, wherein the receiving device comprises a processor and an alarm adapted to be triggered by the beacon message, wherein the processor determines a relevance of the beacon message by comparing the minimum received signal strength for the relevance of the beacon message to an actual received signal strength of the beacon message, wherein, if the actual received signal strength is greater than or equal to the minimum received signal strength, the receiving device is within a range of relevance and the alarm is triggered.

Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals.

A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.
