Notation Question

Other Parts Discussed in Thread: Z-STACK

Hello,

 

What is the difference, if there is any, between the IEEE Address and the Extended Address of a device in a ZigBee network?  They are both the same size (64 bit).  Are they just two ways of referring to the same thing?

 

Thanks,

Stephen Kruzick

    Yes, Extended address and IEEE address are the same. From Z-Stack Developers Guide  -  

    "ZigBee devices have two types of addresses. A 64-bit IEEE address (also called MAC or Extended address) and a 16-bit network address (also called logical address or short address).

    The 64-bit address is a globally unique address and is assigned to the device for its lifetime. It is usually set by the manufacturer or during installation. These addresses are maintained and allocated by the IEEE. More information on how to acquire a block of these addresses is available at http://standards.ieee.org/regauth/oui/index.shtml . The 16-bit address is assigned to a device when it joins a network and is intended for use while it is on the network. It is only unique within that network. It is used for identifying devices and sending data within the network"
