Compairing Communication Protocols in RTLS: Angle of Arrival vs. Phase Ranging

As the Internet of Things (IoT) industry continues to boom, many companies have begun to develop Real Time Location Systems (RTLS) for commercial use cases. There are varying communication protocols that can be used in RTLS to determine a tagged asset’s location.  Some newer communication protocol technologies being used are referred to as Phase Ranging and Angle of Arrival (AoA).  In this article, we will explore the differences between both technologies, as well as benefits and drawbacks to each, as part of a RTLS.
