DotBlue.png Intra-WACN (Wide Area Communications Network) Roaming allows you to configure Motorola radios to operate on certain non-Motorola (Project 25 compatible) in-the-field Trunking Systems. With these non-Motorola in-the-field hardware configurations, the Home WACN ID is the unique ID that requires a Key ID match, which contrast how with Motorola in-the-field hardware, the System ID is the unique ID that requires a Key ID match. DotGreen.png Motorola in-the-field Trunking Systems typically do not have unique Home WACN IDs.

How it Works:

When programming for these non-Motorola in-the-field systems, be aware that the Home WACN ID acts like a typical Motorola System ID, which is why an Advanced WACN Key contains the Key ID that allows for communication access. When programming for Motorola in-the-field systems, the Advanced System Key contains the Key ID that allows for communication access.

Be aware that when programming for these non-Motorola in-the-field systems, Sites can also have unique System IDs.

With these non-Motorola in-the-field systems, there are no "home" or "foreign" Trunking Systems; all Trunking Systems (sites) in a given WACN re-use the same Working Unit IDs (WUIDs) and Working Group IDs (WGIDs), and are essentially treated as the radio's Home System, where each System becomes another “site” within the network.

 

Do the following for any Trunking Systems intending to have CPS-defined channels communicating in an Intra-WACN Roaming scenario:

  1. On the Trunking System, General Page, set the value of the Home WACN ID field to match the "Key ID" of an Advanced WACN Key (see the System Key Report).

DotGreen.png All in-the-field Motorola Trunking Systems use the same Home WACN ID. However, certain non-Motorola vendors deploy their Trunking Systems with unique Home WACN IDs and their “sites” have unique System IDs within that WACN.

  1. Set the Coverage Type of the current Trunking System to “Intra-WACN Roaming”.

  2. Ensure that the System ID and the Unit ID are also set to their appropriate values. The combination of the Home WACN ID, the System ID, and the Unit ID identify a radio and its Home System as it roams within a given Wide Area Communications Network.
