Conclusion

In this theoretical introduction to the operation of Advanced Ranging, we have shown the additional capabilities it can bring to localization and proximity systems:

• In the case of co-localized Master and Advanced Ranging radios, additional range information can be obtained at no additional energy cost for the Slave and no additional cost in bandwidth or radio channel capacity.
• In the case of localization, the Advanced Ranging feature permits the overhearing of ranging exchanges in a fixed Master-Slave infrastructure. This can allow an unlimited number of Advanced Ranging end-nodes to obtain localization information, where the equivalent conventional ranging would demand multiple ranging exchanges between anchor and end node. This results in improved localization capacity and energy consumption.

The numerous architectures and device roles possible when combining ranging and Advanced-Ranging are beyond the scope of this short introduction. However, with the basic principles of the operation of Advanced Ranging defined, designers can evaluate the increased capacity and reduced consumption that Advanced Ranging can bring to an application.
