[Part 1 reviews ZigBee data transmission along with an example that demonstrates how to initiate various data request mechanisms. Part 2 discusses ZigBee's lack of a standard C API and looks at an API sampling from the four "Golden Unit" ZigBee vendors. Part 3 describes PAN IDs, extended PAN IDs, and channels, as well as application examples.]
4.4 ZigBee Addressing
Addressing is the way in which a message gets from one place to another in a network. Postal (snail) mail uses one type of address that many are familiar with:
San Juan Software
221 Wood Duck Lane
Friday Harbor, WA 98250
USA
Internet Protocol (IP) addressing is another addressing method:
155.213.123.01
ZigBee addressing takes into account all the information shown in Table 4.3.
| Name | Range | Description |
| Channel | 11–26 | A physical portion of the RF spectrum |
| PAN ID | 0x0000–0x3fff | The address of a network within a channel |
| NwkAddr | 0x0000–0xfff7 | The address of a node within a network |
| Endpoint | 1–240 | The address of an application within a node |
| Cluster | 0x0000–0xffff | The object within the application |
| Command | 0x00–0xff | An action to take within the cluster |
| Attribute | 0x0000–0xffff | A data item within the cluster |
There are other ZigBee addressing features that simply translate into one or more of the items shown in the table. For example, Extended PAN IDs really merely determine which PAN ID to join. Another is groups, described later in this section, which defines a set of nodes in the network to address (see Table 4.4).
| Name | Range | Description |
| Extended PAN ID | 0x0000000000000000–0xffffffffffffffff | A unique 64-bit identifier for the PAN |
| Group | 0x0000–0xffff | A collection of nodes in a network |
| Application Profile ID | 0x0000–0xffff | Defines a particular application domain |

In table 4.5 column 1 you have your ZED and ZR swapped.
