What Network Topologies Does Wireless Hart Support?

1.	What Network Topologies Does Wireless Hart Support?
Answer» Wireless HART allows for basically three network topologies: Star or point-to-point, Mesh and a combination of Star + Mesh which utilizes the both network topologies. Each topology has advantages and DISADVANTAGES providing flexibility at the time of setup and commissioning. A Mesh topology allows for further network DISTANCE and the ability to adjust for CHANGING communication paths. Compared to other wireless protocols, this functionality provides greater reliability and flexibility as well as eliminating the associated cost and RISK of installing and wiring backbone routers throughout the plant. A Star (point-to-point) topology allows a device to communicate DIRECTLY to the gateway without having to route communications through another device. All Wireless HART devices can operate in a point-to-point topology if a mesh is not desired.
