2 Benefits of Having Multiple Gateway Support

Even though the TI 15.4-Stack offers scalable network features out-of-the-box, features such as node balancing, extended network coverage, and increased node count, need to be implemented at the application layer. This is because a TI 15.4 network operates in a star topology in which only one node serves as PAN coordinator and the rest of the nodes simply report to it.

Having said this, there is nothing in the TI 15.4-Stack that prevents an application from relying on multiple PAN coordinators to form a larger network composed by several TI 15.4 networks.

The following section describes the previously mentioned features, so that the reader can determine whether or not implementing multiple gateway support might be suitable for a particular use-case or end product.
