The Wireless HART mesh topology has many advantages over star topology MAKING mesh the most practical topology option:

• Very ROBUST: multiple paths for maximum reliability under changing plant conditions.
• Network distance can be extended because the critical distance is now between devices in multiple hops, not between DEVICE and the gateway.
• Cost effective because a single gateway can cover a larger network area.
• Low risk deployment because gateway location can be more flexible INCLUDING being installed at the edge of the operating unit using minimal power and backbone networking.
• Flexibility and mobility because devices can be easily added or moved within the network without installing and wiring backbone routers.
• Incremental expansion – additional devices can to be added with BIG savings in deployment time and wiring costs compared to traditional wired installations.
